U-Boot

The source code of U-Boot for Rockchip is available, but more work needs to be done to make it usable for Radxa Rock.

Features

• both common fastboot USB protocol and Rockchip proprietary USB protocol are supported (Rockchip USB tools will work)
• format of partitions (images) are compatible to Rockchip proprietary bootloader (rkcrc, mkbootimg will work)
• (need more investigation...)

Build

git clone https://github.com/radxa/u-boot-rockchip.git
cd u-boot-rockchip

Check out the configuration files and edit them to suit your needs:

board/rockchip/common/armlinux/config.h
board/rockchip/common/platform/rk30/paltConfig.h

Build the bootloader:

make rk30xx

RK3188Loader_uboot.bin will be created. DON'T FLASH IT.
