Currently all RK3188 based devices including the Radxa Rock use the same bootloader from Rockchip. Unfortunately Rockchip do not provide the source code for the bootloader. The bootloaders main task is to:
- Load and boot the kernel.img/boot.img or recovery.img from the corresponding partition.
- Communicate with the host PC to download the image/firmware for upgrading
The bootloader of the Radxa Rock can be downloaded from this address:
http://dl.radxa.com/rock/images/loader/
The analysis of the bootloader is done by sarg. You can contact sarg on IRC on the channel #linux-rockchip if you are interested. You can find the details here:
