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:
