Basics

Skip tutorial

Congratulations if you have got gui working. During the debugging process you will be building and flashing quite a few times, in which tutorial during the setup screen can be annoying. You can skip that by tapping on the each corner of the screen clockwise, while starting from left-top corner.

Updating submodules

Submodule locations: ``` rpm/dhd hybris/droid-configs/droid-configs-device hybris/droid-hal-version-fp2-sibon/droid-hal-version ```

In the each folder check remote name using `git remote -v `

Run (replace remote_name with the name you found out in previous step) ``` git fetch remote_name git pull remote_name master

Updating local build target

Change release version in the command if needed In Platform SDK:

   sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R ssu release 2.1.4.14
   sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper ref
   sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper dup

Finishing Your Port

how to bring store to your device

Your device adaptation should be on Mer OBS (read "Building things on OBS" below)

Do `ssu s`, Device UID should show a unique ID that is: IMEI for devices with modem, note - your GSM modem should provide a valid IMEI even without an inserted SIM! Always a good cross-check that IMEI matches the one on your phone's box or under battery, and in CM/Android For devices without modem -- WLAN or BT MAC address.

Find another port/phone and prove that unique ID there is different than yours, and that all of them persist across reboots. If unique ID is OK then ping pketo on #sailfishos-porters with "Device model" line from `ssu s` to enable store for you.

Building things on OBS:

Benefits: automated builds, Jolla Store (see above), OTA (see below); local PC is then only needed for Android, dhd, and droidmedia building (which barely happen when port becomes stable), and mic image creation

It makes sense to go OBS as soon as you have polished your code, minimised hacks, and pushed it to github (usuall when display+touch+WLAN and maybe cellular are working)

On IRC ask sledges to create project and get maintainership for your nemo:devel:hw:$VENDOR:$DEVICE (you can try things out in your home repo first) ``` Click on Repositories tab in your nemo:devel:hw:$VENDOR:$DEVICE Then "Add repositories" Check "SailfishOS latest" Click "Add selected repositories" at the bottom of the page Add a hw:devel:common repo to build against (which contains all important backports for all ports:), you'll need to add it as an additional repo: Click on Repositories tab in your nemo:devel:hw:$VENDOR:$DEVICE Click "Edit repository" Click Add additional path to this repository Project: nemo:devel:hw:common Repository: sailfish_latest_armv7hl ``` Check how other devices are built here e.g. https://build.merproject.org/project/show/nemo:devel:hw:semc:iyokan

Create droid-hal-$DEVICE package manually and upload RPMs for droid-hal-device and droidmedia (and audioflingerglue if device needs it) For all other packages create webhooks and trigger builds

How to create webhooks: https://wiki.merproject.org/wiki/Packaging/webhooks

Which webhooks will you need for your device: https://webhook.merproject.org/webhook (search for nemo:devel:hw:lge:mako and replicate that structure)

Add cibot as maintainer, then ask lbt via IRC to "patternise" your nemo:devel:hw:$VENDOR:$DEVICE

Build an image successfully on your PC by following HADK but, using .ks file from droid-config-$DEVICE-ssu-kickstarts-*.rpm built on OBS (don't forget to sed the repos and add nemo:hw:devel:common as adaptation1, this will help you more: http://images.devaamo.fi/sfe/mako/gamma6/Jolla-2.0.1.11-mako-armv7hl.ks )

Over-the-Air updates (OTA):

Prerequisities:

Your port has stabilised and is ready to face the big public (gets our retweets, you create Sailfish OS port thread on e.g. XDA, evangelise it :)

Good measure is to have bare necessities of a daily-driver for most people: LED, audio, texts, calls, data, WLAN, GPS, camera, light, proximity, accelerometer, vol keys, vibra, power management

You should be building on OBS (guide above)

Then add these two files (change contents apropriately) - https://github.com/mer-hybris/droid-config-hammerhead/blob/master/sparse/var/lib/flash-partition/device-info

Change `PART_REAL_1` to match "boot" partition of your device Change `CPUCHECK_STRING` to match the Hardware field in `/proc/cpuinfo` - https://github.com/mer-hybris/droid-config-hammerhead/blob/master/sparse/var/lib/platform-updates/flash-bootimg.sh

Don't forget to make it executable

Port over to your device this line: - https://github.com/mer-hybris/droid-hal-hammerhead/blob/ca102d255f1b6f274e2768e8cbd4ad9c631890e9/droid-hal-hammerhead.spec#L12

And this commit (only if MultiROM exists or in-the-works for your device): https://github.com/mer-hybris/droid-config-hammerhead/commit/cb39670de095b914aea23d6ce0e633d295493016 Don't forget to commit and tag so configs rebuild on OBS :) Simulate OTA on :devel: https://wiki.merproject.org/wiki/Template:SFOS_OTA , see if all is fine (e.g. you can build devel 1.1.9.28 image and OTA it to 2.0) Then you can test how an updated kernel package flashes itself automatically with an extra reboot, by making some change in kernel, reuploading RPMs and simulating OTA again For your users to actually use OTA, you should move it to :testing (on IRC ask sledges to create nemo:testing:hw:$VENDOR:$DEVICE), to still be able to play (i.e. break things) in your :devel

Get maintainership on that :testing repo - Add cibot as maintainer, then via IRC ask lbt to "patternise" that repo too - Click on Repositories tab in your nemo:testing:hw:$VENDOR:$DEVICE - Then "Add repositories" - Then "pick one via advanced interface" - Start typing "sailfishos", then pick the version you want OTA to be available for in format "sailfishos:X.Y.Z.W" - Choose "latest_$PORT_ARCH" for your architecture - Make the "Name" to match exactly "sailfishos_X.Y.Z.W" - Add nemo:testing:hw:common to that as additional repo just like you did with :devel: above

Ensure NO webhooks point to :testing ! Cross-check with https://webhook.merproject.org/webhook

Promote by using osc copypac to all your device packages from devel to testing (useful script: http://pastebin.com/GssLRr8e )(How To https://gist.github.com/taaem/53ed3a99893d323d7ab3bd8d07540f50 ) - use this (or simpler "Submit Package" WebUI option) also in future whenever a HW adaptation package needs updating in between sfos releases (PR is being prepared to add device hw version to zip filename, HW Adaptation version is also shown in About Product, and is incremented by 1 each time OBS automatically rebuilds droid-hal-version-$DEVICE whenever any hw package changes ;))

Make an image with adaptation-community repo pointing to testing, adaptation-community-common pointing to common in your .ks file, and start distributing that to the rest of the world Don't forget to document everything, create a nice installation wiki article for your device (if not yet already), and add such section: https://wiki.merproject.org/wiki/index.php?title=Adaptations/libhybris/Install_SailfishOS_for_mako&action=edit&section=4 Point your existing users to the OTA section of your device's wiki

Once the next Sailfish OS release comes out and your port adopts it, you can create a new repository in OBS with that version and your users will OTA to it.

Debugging Tips

Determine which is the touch event

use command "getevent" as super user in adb shell. The event which spams most outputs on the screen when the screen is touched is the touch event.

persistent journalctl:

modify /etc/systemd/journald.conf :

   Storage=volatile --> Storage=automatic

Then do: ``` mkdir /var/log/journal reboot ```

Systemd suppresses journal, and some valuable info might get hidden. To prevent this, set

   RateLimitInterval=0

monitoring udev events

udevadm monitor is your friend.

To get it for cyanogenmod, add this repository https://github.com/chombourger/android-udev/ to your manifest as external/usb and make udevadm

To monitor boot-time events, compile the kernel with CONFIG_DEBUG_KOBJECT=y and increase the log buffer size by setting the kernel command line option: log_buf_len=21 (or higher)

perf :)

   MER_SDK $
   cd $ANDROID_ROOT
   mkdir -p perf/rpm
   cd perf
   ln -s $ANDROID_ROOT/kernel/$VENDOR/$DEVICE linux
   curl -o rpm/perf.spec http://pastebin.com/raw/QiW7FD02
   
Replace string <YOUR_KERNEL_VERSION> in rpm/perf.spec with kernel version for which you're building perf (for example: 3.4.0)

   mb2 -s rpm/perf.spec -t $VENDOR-$DEVICE-armv7hl build
   mv RPMS/*.rpm $ANDROID_ROOT/droid-local-repo/$DEVICE/
   createrepo $ANDROID_ROOT/droid-local-repo/$DEVICE

"less" package is needed for perf to format its output. You can find it here: - http://repo.merproject.org/obs/nemo:/testing:/hw:/common/sailfish_latest_armv7hl/

HADK Fixes

Issues with pulseaudio module build

downgrade hybris/droid-configs/droid-configs-device as described above by going to the folder and running

git reset --hard 769864929261d14ba2380323ddced4e325d5c819
build_packages.sh --configs

Issues with ngfd or ngfd-plugin-droid-vibrator or pulseaudio

Update submodules as described above Downgrade hybris/droid-configs/droid-configs-device by going to the folder and running

   git reset --hard 769864929261d14ba2380323ddced4e325d5c819
   

Replace `%define have_vibrator 1` in droid-hal-version-@DEVICE@.spec with `%define have_vibrator_native 1` Change package names in droid-configs patterns as described in templates https://github.com/mer-hybris/droid-hal-configs/commit/aac652aae840a15629c0f4e070275ea128fe088f Downgrade ngfd plugin: Go to hybris/mw/ngfd-plugin-droid-vibrator and run:

   git reset --hard 3e2b4fb5b03a6d3db9ca5a41c7091e771f99cc4f

IN PLATFORM_SDK:

    $PLAFORM_SDK
    rpm/dhd/helpers/build_packages.sh -b hybris/mw/ngfd-plugin-droid-vibrator -s rpm/ngfd-plugin-native-vibrator.spec
   
    sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -m sdk-install -R zypper rm ngfd-plugin-droid-vibrator
    rpm/dhd/helpers/build_packages.sh -b hybris/mw/ngfd-plugin-droid-vibrator --spec=rpm/ngfd-plugin-native-vibrator.spec

when you run the whole build_packages.sh after this skip the ngfd-plugin-native-vibrator build

libminisf.so not found

Add libminisf to droidmedia make command like this in HABUILD_SDK:

   make -jXX libdroidmedia minimediaservice minisfservice libminisf

Also update rpm/dhd submodule in case you have an older version


No installroot directory after droid-configs build when preparing .ks file

   rpm2cpio droid-local-repo/$DEVICE/droid-configs/droid-config-$DEVICE-ssu-kickstarts-1-1.armv7hl.rpm | cpio -idmv

in the sed command use `$ANDROID_ROOT/usr/share/kickstarts/$KS` instead of `$ANDROID_ROOT/hybris/droid-configs/installroot/usr/share/kickstarts/$KS`

Building droid-config fails with: Segmentation fault (core dumped) /usr/lib/qt5/bin/kmap2qmap .........

try updating the packages in the target with sb2 -t $VENDOR-$DEVICE-armv7hl -R -m sdk-install zypper ref sb2 -t $VENDOR-$DEVICE-armv7hl -R -m sdk-install zypper dup

or

add the file /system/build.prop to the target with the contents


mic fails during the run

If you get error like this Warning: repo problem: pattern:jolla-hw-adaptation-$DEVICE1-1.noarch requires droid-config-$DEVICE-policy-settings, but this requirement cannot be provided, uninstallable providers: droid-config-$DEVICE-policy-settings-1-1.armv7hl[adaptation0-$DEVICE-2.0.1.7]

Or for example No provider of 'pkgconfig(qofonoext)' found.

In these cases the missing dependencies can be added with the command:

   MER_SDK $
   sb2 -t $VENDOR-$DEVICE-$PORT_ARCH -R -m sdk-install ssu ar common http://repo.merproject.org/obs/nemo:/devel:/hw:/common/sailfish_latest_armv7hl/

Also add the same repo to .ks file before building the installation package with mic Run the following commands before chapter 8.3 of HADK pdf

   MER_SDK $
   cd $ANDROID_ROOT
   MOBS_URI="http://repo.merproject.org/obs"
   HA_REPO="repo --name=adaptation0-$DEVICE-@RELEASE@"
   HA_REPO1="repo --name=common --baseurl=$MOBS_URI/nemo:/devel:/hw:/common/sailfish_latest_@ARCH@/"
   sed -i -e "/^$HA_REPO.*$/a$HA_REPO1" tmp/Jolla-@RELEASE@-$DEVICE-@ARCH@.ks

If MIC fails with RuntimeError: Invalid runmode: native remove `--runtime=native` from mic command args

If the error message ends with CreatorError: <creator>Unable to find pattern: Jolla Configuration $DEVICE then make sure that you executed 8.4 in the hadk pdf (as of v1.9.9). If it still does not work, try executing it again, then process patterns and build again. If the ks file generated in $ANDROID_ROOT does not contain the local repo, then add it manually. To the top of the list of repos, add "repo --name=adaptation-community-$DEVICE-@RELEASE@ --baseurl=file:$ANDROID_ROOT/droid-local-repo/$DEVICE/" substitute $DEVICE and $ANDROID_ROOT appropriately. Process patterns and build again.

sudo: effective uid is not 0, is sudo installed setuid root?

Just after chroot is entered through the `sdk` command, sudo fails to execute and fails with the previous message

check for suid mount flag in the bind-mounted root: if your home (not chroot home) is mounted with nosuid you need to remount it before chroot

     $HOST
     sudo mount -o remount,suid $HOME

If you're running an encrypted home partition with ecryptfs, you need to remount home anyway, even if nosuid flag is not set

     $HOST
     sudo mount -i -o remount,suid $HOME) 

repo init -u git://github.com/mer-hybris/android.git -b hybris-11.0 fails because of gpg In sdk chroot gpg command is gpg2

     $MERSDK
     git config --global gpg.program gpg2

existence_error (yes, you read that right) when locally building policy-settings-common:

You get: ERROR: error(existence_error(procedure, qsave_program/2), context(precompile/0, _G669)) Solution: ``` sb2 -t $VENDOR-$DEVICE-armv7hl -R -msdk-install cd /usr/lib/swipl-5.6.50/library rm INDEX.pl zypper in fakeroot fakeroot swipl -g true -t 'make_library_index(.)' ``` then rebuild the package again with mb2

Nothing provides /system/bin/sh:

Add this to your .spec

   %define __provides_exclude_from ^/system/.*$
   %define __requires_exclude ^/system/bin/.*$
   %define __find_provides %{nil}
   %define __find_requires %{nil}

rpm/dhd/helpers/build_packages.sh fails building libhybris, ...

Adaptation Guides

ff-memless haptics

To use memless haptics driver instead of droid-vibrator, you need a kernel haptics driver that supports a memless interface (evdev). This is briefly explained in HADK pdf chapter 13.1. Reference kernel driver implementation for qpnp vibrator is here; https://github.com/kimmoli/android_kernel_oneplus_msm8974/pull/1

It needs also vibrator configuration files if defaults are not ok; (this is also in HADK) https://github.com/kimmoli/droid-config-onyx/commit/dac479716a6b4300be3c5875982265f6914bb498

And depends which evdev index the new ffmemless gets, one might need to change lipstick config; https://github.com/kimmoli/droid-config-onyx/pull/4/commits/73bb85fcdc5e2627a8cb0cea0fb5fc2ca9d8e814

in droid-hal-version-$DEVICE.spec comment `%define have_vibrator 0` out and add `%define have_ffmemless 1`

add build of qt5-feedback-haptics-ffmemless in build_packages.sh, and comment out other vibrator packages;

   buildmw "https://git.merproject.org/mer-core/qt-mobility-haptics-ffmemless.git" rpm/qt5-feedback-haptics-ffmemless.spec || die

FM Radio support

Needs a device with suitable FM radio hardware and a kernel defconfig containing `CONFIG_RADIO_IRIS=y` and `CONFIG_RADIO_IRIS_TRANSPORT=m (or =y)`

If your `CONFIG_RADIO_IRIS_TRANSPORT` is built-in then this is not needed, however if you have problems try building `CONFIG_RADIO_IRIS_TRANSPORT` as a module: add (adapt to fit your device if needed) - https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/lib/systemd/system/droid-fm-up.service - https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/lib/systemd/system/bluetooth.service.wants/droid-fm-up.service

Sometimes device permissions are wrong (root owner), in this case: - Add https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/lib/udev/rules.d/999-droid-fm.rules to your droid-configs repo (or directly to device for testing) - Add qt5-qtmultimedia-plugin-mediaservice-irisradio to patterns (or install directly to device for testing) - Add https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/etc/pulse/xpolicy.conf.d/fmradio.conf to your droid-configs repo (or directly to device for testing)

(pre-2.0.2) Update packages from http://repo.merproject.org/obs/nemo:/devel:/hw:/common/sailfish_latest_armv7hl/ (for building new images add this to your .ks file as described elsewhere in FAQ)

Starting from Sailfish OS 2.0.2 FM radio Media app plugin jolla-mediaplayer-radio can be added to patterns.

(pre-2.0.2) For FM radio testing harbour-piratefm can be obtained from - http://repo.merproject.org/obs/home:/kimmoli/sailfish_latest_armv7hl/

Flashlight shortcut

Starting from Sailfish 2.0.2 it's possible to have flashlight shortcut in eventsview. If your device supports flash torch mode add jolla-settings-system-flashlight package to patterns in your droid-configs repo. The shortcut can be enabled in the eventsview settings.

Notes on LOS14.1 Porting

XXX: remove the word "exec" from the last line of /usr/bin/droid/droid-hal-startup.sh, to make this permanent add a modified copy of the file to $ANDROID_ROOT/hybris/droid-configs/sparse/usr/bin/droid/droid-hal-startup.sh (this has to be fixed properly at some point)

On mixed 32/64bit devices, LD_LIBRARY_PATH could be wrong. If logcat shows services aborting with SIG 6 due to wrong arch, try removing the LD_LIBRARY_PATH from /init.environ.rc

Graphics performance improvements

Test framerate display (can be enabled in Settings->Developer mode) when using some apps like gallery If the top view is mostly red try to set QPA_HWC_IDLE_TIME=5 in /var/lib/environment/compositor/droid-hal-device.conf Run ```systemctl restart user@100000 using devel-su```

Test framerate display again and if you see more green than before you should use the value

Different values can be tested but value 5 has been found to be helping on some devices

On some devices also setting `QPA_HWC_BUFFER_COUNT=3` in `/var/lib/environment/compositor/droid-hal-device.conf` helps with graphics performance

Using backported Bluetooth drivers in 3.4 kernel for devices with Qualcomm bluetooth chip using hci_smd driver

Generic guide: https://bluez-android.github.io/#building-own-kernel

Sailfish specific guide:

Build your kernel with patches from https://github.com/bluez-android/misc/tree/master/patches-kernel and with following flags defined in defconfig

   CONFIG_BT=m
   CONFIG_CRYPTO_CMAC=y
   CONFIG_CRYPTO_USER_API=y
   CONFIG_CRYPTO_USER_API_HASH=y
   CONFIG_CRYPTO_USER_API_SKCIPHER=y

NOTE: Patches may not be required for >= 3.18 In your local_manifest, add ```<project name="mlehtima/backports-bluetooth" path="external/backports-bluetooth" revision="master" />``` run repo sync in HABUILD_SDK

Build backported drivers by running make backports in HABUILD_SDK while in $ANDROID_ROOT folder if you get `"external/backports-bluetooth/drivers/bluetooth/hci_smd.c:35:26: fatal error: mach/msm_smd.h: No such file or directory" `error change `#include <mach/msm_smd.h> to #include <soc/qcom/smd.h|>` in that file

IMPORTANT: if you rerun make hybris-hal at any time you will always have to rerun make backports after that Package droid-hal as usual

Change your config repo to use bluez5 https://github.com/mlehtima/droid-config-fp2-sibon/commit/1cba868fdcfebaffc14a084c5d82fbf2e4339173 Rebuild config rpms and image

EA Scratchbox Targets

Lately Jolla offers two sb2 targets so the HADK instructions create some strange behaviour when downloading the sb2 target

You have two options now to replace this line

TARBALL=$(curl $TARBALL_URL | grep "$PORT_ARCH.tar.bz2" | cut -d\" -f4)

to change pixel ratio on a running device, as user:

``` devel-su dconf update

  1. PIXEL_RATIO should be close to the value of horizontal_display_resolution/540
  2. e.g. Nexus 7 (800 x 1280) displays the pixel ratio is 800/540~=1.48
  3. always round the value up with two decimal precision

PIXEL_RATIO=1.48

  1. UPDATE! Please test the new formula for pixel ratio calculation:
  2. diagonal_display_size_inches/4.5 * horizontal_display_resolution/540
  3. and feedback the outcome to sledges via IRC (better/worse/closer via own trial&error picks?)
  4. Yet another formula: YourDevicePPI/sbjPPI (245), e.g. OnePlusX PPI 441/245 = 1.8
  5. Available ICON_RES values are 1.0, 1.25, 1.5, 1.75, and 2.0. Choose the closest one to PIXEL_RATIO:

ICON_RES=1.5 devel-su zypper in jolla-ambient-z$ICON_RES ambient-icons-closed-z$ICON_RES dconf write /desktop/sailfish/silica/theme_pixel_ratio $PIXEL_RATIO dconf write /desktop/sailfish/silica/theme_icon_subdir $

  1. check that everything worked:

dconf read /desktop/sailfish/silica/theme_pixel_ratio devel-su reboot

make[3]: *** [security/commoncap.o] Error 1... Those errors appears because ANDROID_CONFIG_PARANOID_NETWORK is disabled in your kernel and with it enabled, you can't access internet with Sailfish OS. ( Since hybris-12.1, rild does not work without ANDROID_CONFIG_PARANOID_NETWORK. Add nemo to group inet if it is enabled.) Check http://forum.xda-developers.com/showpost.php?p=42880275&postcount=104 To resolve this replace in <path of your kernel>/security/commoncap.c : ``` if (cap == CAP_NET_RAW && in_egroup_p(AID_NET_RAW))

       return 0;

if (cap == CAP_NET_ADMIN && in_egroup_p(AID_NET_ADMIN))

Save the file and recompile the kernel

Build Wlan Driver as Module

Most devices require the wlan driver to be built and loaded as a module during startup Ensure you have CONFIG_MODULES=y in your kernel config

Find your wifi driver in your kernel config, it should already be set to `y` and have something like WLAN in the name. Set it to m eg. CONFIG_BCMDHD=m CONFIG_PRIMA_WLAN=m CONFIG_PRONTO_WLAN=m

Add the wlan-module-load.service to your droid-configs sparse directory https://github.com/mer-hybris/droid-config-onyx/blob/master/sparse/lib/systemd/system/wlan-module-load.service

and add a symlink to enable to service on startup: https://github.com/mer-hybris/droid-config-onyx/blob/master/sparse/lib/systemd/system/multi-user.target.wants/wlan-module-load.service

Bluetooth for Qualcomm devices

Enable `CONFIG_BT_HCISMD` in the kernel defconfig. If it is not present in your kernel, then make these changes: - https://github.com/adeen-s/android_kernel_cyanogen_msm8916/commit/4627f4f6f5d886433ff1f9639dc18fe8a006fd00

Add these files to sparse (or directly to device) and modify them as needed for your device --> - https://github.com/adeen-s/droid-config-wt88047/blob/master/sparse/usr/bin/droid/droid-hcismd-up.sh - https://github.com/adeen-s/droid-config-wt88047/blob/master/sparse/lib/systemd/system/droid-hcismd-up.service - https://github.com/adeen-s/droid-config-wt88047/blob/master/sparse/lib/systemd/system/bluetooth.service.wants/droid-hcismd-up.service

Bluetooth Should now work. If it doesn't then make sure the permissions are set correctly and all paths mentioned in above files point to valid locations.

If you are still having trouble, check to see if there is a service that configures bluetooth and disable/comment it. Eg, config_bluetooth in init.qcom.rc


Bluetooth for Broadcomm devices

Enable `CONFIG_BT_HCIUART_H4` in the kernel defconfig. These devices typically are attached on high speed uart to something like /dev/ttyHS0

- Symlink your firmware file to /etc/firmware. eg. https://github.com/r0kk3rz/droid-config-scorpion_windy/blob/master/sparse/etc/firmware/BCM4350C0.hcd

- You need to make sure the firmware symlink filename matches your bluetooth device name, which can be found by stracing hciattach Build rfkill middleware and add to patterns: ``` rpm/dhd/helpers/build_packages.sh --mw=https://github.com/mer-hybris/bluetooth-rfkill-event --spec=rpm/bluetooth-rfkill-event-hciattach.spec ``` - add configs: https://github.com/mer-hybris/droid-config-f5121/commit/afa01bdf4bdb8a0d16bbd34996ec7cac34bbbc55

Ofono problems

RILD is running but ofono does not work If ofono is not working properly and shows "ERROR! Can't connect to RILD: No such file or directory" in logs, edit /etc/ofono/ril_subscription.conf to contain

   [ril_0]
   name=RIL1
   socket=/dev/socket/rild

if your device is dual SIM, add also these lines (don't add them otherwise!):

   [ril_1]
   name=RIL2
   socket=/dev/socket/rild2

If it works add your ril_subscription.conf to the droid-config-$DEVICE like done here https://github.com/Nokius/droid-config-find5/commit/3e3e636e7e3973f9102ebca9dea79794c00c9174 Also add the jolla-settings-networking-multisim to patterns like done here https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/patterns/jolla-configuration-fp2-sibon.yaml#L15 Fix remembering manual access point configurations across reboots run the following command before building the image sed -i "/begin 60_ssu/a chown -R radio:radio /var/lib/ofono" Jolla-@RELEASE@-$DEVICE-@ARCH@.ks

Devices without modem File /etc/ofono/ril_subscription.conf should contain

   [Settings]
   EmptyConfig=true

Device Fixes

Problems with tfa9890

Copy `/system/etc/firmware` to `/etc/firmware`. Symlink or mount doesn't work! (But why?)

So you booted your Sailfish OS? Congrats! No GUI? Oh dear :)

both usb0 and rndis0 interfaces might be up, remove usb0 from init-script and rebuild kernel image with make hybris-boot or make hybris-recovery


lipstick segfaults/no display

As you follow steps below, strace any of the binaries that would fail for non-obvious reasons. You'll need to install strace to do so: zypper in strace test simple hwc as root:

   EGL_PLATFORM=hwcomposer test_hwcomposer

^^ strace if segfaults if strace dies after open("/sys/kernel/debug/tracing/trace_marker..., perform

   systemctl mask sys-kernel-debug.mount

test_hwcomposer should not be used as reliable hwc test!! if fails, then try minimer:

   curl -O https://qtl.me/minimer3.tar.gz
   zypper in qt5-qtdeclarative-qmlscene
   tar -xf minimer3.tar.gz; cd minimer
   EGL_PLATFORM=hwcomposer /usr/lib/qt5/bin/qmlscene -platform hwcomposer main.qml

if fails as user, try as root /system/bin/surfaceflinger for more info: zypper in gdb if you get test_hwcomposer, minimer or lipstick segfault, or test_hwcomposer or minimer running but doing nothing (as on m7) Check if your device uses qcom_display-caf or display-legacy Look in any of the BoardConfig.mk or BoardConfigCommon.mk in any of the device repos for the device for the variable TARGET_QCOM_DISPLAY_VARIANT. It should be set to either caf or legacy. The repos included can be determined by looking at the -include device/$VENDOR/*/BoardConfig.mk or device/$VENDOR/*/BoardConfigCommon.mk lines at beginning the .mk files starting from the primary BoardConfig.mk If you're on display-legacy or display-caf(repo sync before 2015.06.04) patch hwcomposer withhttp://pastebin.com/AfRXPKVA From HABUILD_SDK recompile android hwcomposer*.so for your device Find the name of the hwcomposer*.so module: run make modules | grep hwcomposer If this command complains about missing column command run sudo apt-get install bsdmainutils) Run `make hwcomposer.module_name` from results above Once rebuilt, hwcomposer.*.so will be picked up and used by droid hal rebuild, and reside under /usr/libexec/droid-hybris/system/lib/hw If your apps are crashing (like on flo): Repeat the same for gralloc and copybit Scream on the IRC if this worked for you If strace indicates something like:

"Waiting for service display.qservice..." This error is known only on cm-10.1 base, and will be upstreamed to mer-hybris soon, but we need more tests: applyhttps://github.com/mer-hybris/android_frameworks_native/commit/6ed4a6e834f6c71b2b6bd8ae1134f50b060e70be to this line https://github.com/CyanogenMod/android_frameworks_base/blob/cm-10.1/cmds/servicemanager/service_manager.c#L88 and also apply https://github.com/mer-hybris/android_system_core/commit/34ea48fd3ad7bf47ec0d0524d76bd20e62717773 open("/sys/kernel/debug/tracing/trace_marker", O_WRONLY|O_LARGEFILE) = disable debugfs by: https://github.com/mer-hybris/droid-hal-device/commit/8d437fc6f215081d4e1d2baaa6ac23bb94f73154 if it still crashes on gralloc or other gpu related bits, refer to WIP: https://wiki.merproject.org/wiki/Adaptations/libhybris/gpu

SIM card not detected

This often causes a bootloop Cellular Modem bringup is now in HADK v1.1.1 section 13.3

Additional checks: - Replicate /dev/block structure from Android as closely as possible (for rild to be able to access the modem partition) - Run ls -lR /dev/block in CM - Run ls -lR /dev/block in Sailfish OS

diff the two outputs (this is WIP - android's toolbox ls might need more parameters to produce a comparable output) If you see differences you need to add custom udev rules to create the correct /dev/block structure (added automatically since 2016-12-10) For devices with /dev/block/platform/msm_sdcc.1/by-name/ paths (msm_sdcc.1 can be different) add to $ANDROID_ROOT/rpm/ these paths and files with contents, and it most probably will help (but still paste your diff to the IRC channel):

- https://github.com/mer-hybris-kis3/droid-config-kis3/blob/master/sparse/lib/udev/platform-device - https://github.com/mer-hybris-kis3/droid-config-kis3/blob/master/sparse/lib/udev/rules.d/998-droid-system.rules

(added automatically since 2017-06-03) Some devices (at least all hybris-13.0 based ports) have /dev/block/bootdevice/by-name/ as /dev/block structure in CM in which case you need to add the following line to the end of the 998-droid-system.rules file in the last link:

   ENV{ID_PART_ENTRY_SCHEME}=="gpt", ENV{ID_PART_ENTRY_NAME}=="?*", IMPORT{program}="/bin/sh /lib/udev/platform-device $env{DEVPATH}", SYMLINK+="block/bootdevice/by-name/$env{ID_PART_ENTRY_NAME}"

If you have logcat and journal error messages suggesting that RIL/ofono can't power the modem on and you have a qcom chipset, have a look in your init.qcom.rc for lines that power it on when the boot animation (bootanim) stops. If you have those, try this (paths may need correcting): https://github.com/stephgosling/android_device_htc_m7-common/commit/9f4abdca65356090e6dd6f0356c5cf4a1870aa5f (note the typo there in the chown line!)

If you have `pil-q6v5-mss fc880000.qcom,mss: modem: Failed to locate modem.mdt` in your `dmesg` then try this steps:

- Mask firmware.mount - add this service to /lib/systemd/system/ https://pastebin.com/9tbUtVnC - create symlink to that service in /lib/systemd/system/local-fs.target.wants/ - add /usr/bin/droid/extract_firmware.sh with this content https://pastebin.com/bgphKn4z


Waiting for service SurfaceFlinger seen in logcat? then read this (read surfaceflinger-hack below)

If you are using a service like lipstick-hack which loads surfaceflinger for a few seconds to init the hardware, then this stops servicemanager seeing minisfservice as SurfaceFlinger becuase it uses the same service name, then dies. Disable/mask lipstick-hack from being started by systemd Add lipstickhack to /init.rc and start in the the core class

service lipstickhack /usr/bin/droid/lipstick-hack.sh
class core
user system
oneshot
group graphics drmrpc

Alternative to lipstick-hack (aka surfaceflinger-hack)

For devices that need the so called lipstick-hack to start surfaceflinger for a few seconds to init the hardware we developed an alternative as the lipstick-hack has proven to be rather unstable during system boots.

This alternative uses a modified version of libsurfaceflinger itself to init the display and then exits it's main run loop and afterwards behaves like minisfservice. This eliminates the timing issues of lipstick-hack.

Implementation: 1. BoardConfig.mk - in the BoardCommon.mk of your device add the following lines:

# SurfaceFlinger init
BOARD_USE_MOTO_SF = true

2. libsurfaceflinger - apply the patches from https://github.com/guhl/android_frameworks_native/commit/ead91374111114fded280abe56484523355ee2cc to $ANDROID_ROOT/frameworks/native/services/surfaceflinger - in HABUILD_SDK build libsurfaceflinger by doing:

source build/envsetup.sh
breakfast $DEVICE
make libsurfaceflinger


3. - apply the patches from https://github.com/guhl/droidmedia/commit/cf176cd1bec2c0e5b633b8d728528edc6133ed7d to $ANDROID_ROOT/external/droidmedia - build droidmedia as described in HADK v2.0.1 - chapter 13.2

4. init.rc - add minisfservice as a service to your $ANDROID_ROOT/system/core/rootdir/init.rc like this:

service minisf /usr/libexec/droid-hybris/system/bin/minisfservice
    setenv LD_PRELOAD /usr/libexec/droid-hybris/system/lib/libsurfaceflinger.so
    class main
    user system
    group graphics


5. rebuild hybris-hal as described in HADK v2.0.0 - chapter 5.4 and afterwards package Droid HAL and build the Root Filesystem

Audio not routed to headphones

run evdev_trace from mce-tools package and find /dev/input/eventX that detects headphones connection. It will be the one with SW_HEADPHONE_INSERT* and SW_MICROPHONE_INSERT* like here:


 ----====( /dev/input/event0 )====----
 Name: "sensorprocessor"
 ID: bus 0x0, vendor, 0x0, product 0x0, version 0x0
 Type 0x00 (EV_SYN)
 Type 0x01 (EV_KEY)
        KEY_VOLUMEDOWN KEY_VOLUMEUP KEY_POWER KEY_CAMERA KEY_MEDIA KEY_VOICECOMMAND
 Type 0x05 (EV_SW)
        SW_LID SW_HEADPHONE_INSERT* SW_MICROPHONE_INSERT*


Add this https://github.com/mlehtima/droid-config-fp2-sibon/blob/master/sparse/etc/ohm/plugins.d/accessories.ini file and replace jack-match and jack-device with values from evdev_trace: jack-match matches Name: field and ack-device matches /dev/input/eventX where X is your device input number

Optional way for devices without headphone connector event device:

If your device doesn't have event device for the headphone jack then it might have a switch in /sys/class/switch/h2w/ or similar path If the state file in the /sys/class/switch/h2w/ or similar path reacts to headphone connection by changing the value it can be used for headphone detection Add file /etc/ohm/plugins.d/accessories.ini with the following content (replace switch name with the name found in the path on your device)

   model = uevent
   switch = h2w

If the headphone detection works then add the file to your config repo sparse for future builds
