Introduction
Currently all RK3188 based devices including the Radxa Rock use the same bootloader from Rockchip.
Its main task is to:
- Load and start the kernel/boot images or recovery image from the corresponding partitions.
- Communicate with the host PC to download the image/firmware for upgrading
Download
The bootloader of the Radxa Rock can be downloaded from this address:
http://dl.radxa.com/rock/images/loader/
Source code
The bootloader is based on U-boot and source code is available now:
https://github.com/neo-technologies/rockchip_u-boot
TODO: Add instructions to build bootloader from source.
Recovery
If you get issues when flashing a new bootloader from development sources and your board doesn't seem to boot anymore, then read unbrick page to fix it and flash official Rockchip's bootloader.
