Instalation

U-Boot

Clone u-boot (master branch):

git clone github.com/u-boot/u-boot

Compile u-boot

export CROSS_COMPILE=aarch64-linux-gnu-
ARCH=arm64 make clean
ARCH=arm64 make sopine_baseboard_defconfig
ARCH=arm64 make

Prepare you sd-card

Copy to first sector on SD card:

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=8k seek=1

You can create a boot partition on the SD card with the first MB empty (used by U-boot), GParted -> EXT4 formatting, leave the defaults. I created 2 partitions: a small one for the U-boot stuff and other for maybe later the data.

Manual load kernel

Serial TTY Baudrate UART = 115200 for screen, example: screen /dev/ttyUSB0 115200 You have to start screen first, before turning on the dev kit. Interrupt the U-boot autoboot process when you see the message in the U-boot prompt. We need to access the U-boot prompt to load the Kernel image and boot it! Kernel loading

ext4load mmc 0:1 ${kernel_addr_r} <IMAGE NAME> should be /Image
ext4load mmc 0:1 ${fdt_addr_r} /sun50i-a64-sopine-baseboard.dtb

Boot kernel

booti ${kernel_addr_r} - ${fdt_addr_r}
