BSP Building
Host require few tools/packages to build BSP, install them from host
U-Boot
$ git clone https://github.com/amarula/u-boot-amarula
$ cd u-boot-amarula
$ git checkout -b rock-pi origin/rock-pi
$ make rock-pi-n8-rk3288_defconfig
$ make
Linux
$ git clone https://github.com/amarula/linux-amarula.git
$ cd linux-amarula
$ git checkout -b rockpi origin/rockpi
$ make mrproper
$ ARCH=arm make multi_v7_defconfig
$ ARCH=arm make LOADADDR=0x02000000 uImage dtbs -j 4
Buildroot
$ git clone git://git.buildroot.net/buildroot
$ cd buildroot
$ make rock_pi_n8_defconfig
$ make
SD Boot
In the output/images directory, flash sdcard.img on to micro sd
$ sudo dd if=output/images/sdcard.img of=/dev/sdX status=progress (X - find it from fdisk -l)
$ sync
VMARC RK3288 SOM used on this board looks for images on EMMC and then SD(EMMC is the first in boot order). If EMMC has a valid image then it boots from EMMC. To make SD boot, follow the below link to erase EMMC. It is also valid for RK3288.
EMMC erase notes RK3288 EMMC
Put the micro-SD card onto your board in the slot and power the board. You should see something like:
