The good news is that there is sufficient support in the mainline kernel and with the addition of the patches maintained by OpenWRT we can produce recent kernels 2.6.38.8 and 3.1 to access most of hardware.
The current gaps are PowerPVR drivers, DSP?, GPS, ...

- Adaptation is in
- COBS home:cxl000:n810:testing 2.6.38.8 kernel, utility programs and configuration
- COBS home:cxl000:n810:l31 3.1 kernel
- The current kernels have both be used to boot a N810 to X using fbdev driver.
- watchdog keepalive
- X Configuration to enable access to all keyboard keys with touchscreen calibrated.
- WiFi calibration data is extracted and stored to the firmware directory
- With the WiFi firmware from Maemo the p54spi WiFi driver has been loaded, hw ether address
- manual set and connection to WPA2 enabled Access Point established using connman-test.
- Battery Management calibration data is extracted to firmware directory
- X omapfb driver works
- RTC patches enables reading sane time values. Offset read from calibration area
Adaptation ToDo
- WiFi extract and set hw ether address
- N800 touchscreen calibration
- hardware clock
- Sound
- Bluetooth
- USB/Host/OTG
- USB gadgets (Network)
- lock key
- keyboard slide
- other keys
- camera
- battery management
- keyboard backlight
- indicator LED
- UI integration
- N800 FM radio
- GPS
To Build
- Current Kickstart file n810-armv6l-razor01.ks
- Use mic2 to create a raw image
- mic-image-creator --pkgmgr=yum --prefix=n810 --tmpdir=/tmp --fstype=vfat --format=raw --cache=your-cache --arch=armv6l --record-pkgs=name --config=n810-armv6l-razor01.ks --outdir=your-outdir --overlay-size-mb=64 --logfile=your-logfile
- dd to external card
- mount root partition p1
- copy bluetooth and WiFi firmware to firmware directory
- mount boot partition p3
- copy the zImage from boot partition
Images available
- http://images.formeego.org/n810/
- n810-armv6l-razor01.ks
- Based on Mer release 2011-11-11
- Provides basic Razor/QtDesktop with calibration touchscreen and working keyboard on N810
- n810-armv6l-razor02.ks
- Based on Mer release 2011-11-14
- This includes a system testing and information gathering tool
- After copy image mount root and place you WiFi MAC address in /etc/ethers and driver firmware from Maemo in /lib/firmware
- This will start xinput_calibration so N800 users can calibrate there touchscreen (If you have a N800 please provide a copy from /var/log/cxlinfo0/xinput_calibration for inclusion in future images.)
- n810-armv6l-razor01.ks
To Run
- record you WLAN MAC
- boot using flasher
- start xterm and su root
- ifconfig wlan0 down
- ifconfig wlan0 hw ether <your WLAN MAC>
- ifconfig wlan0 up
- systemctl restart connman
- /usr/lib/connman/test/test-connman list
- record the connman ID for your AP SSID
- /usr/lib/connman/test/test-connman remove <ID>
- /usr/lib/connman/test/test-connman passphrase <ID> <yor AP passphrase>
- /usr/lib/connman/test/test-connman connect <ID>
