Features

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

For NAND flash

Build

Refer install toolchain if you don't have arm-eabi- on your system. Other toolchain(Linaro arm-linux-gnueabihf-gcc 4.9) may cause data abort errors.

git clone -b u-boot-rk3188 https://github.com/radxa/u-boot-rockchip.git
cd u-boot-rockchip
make rk30xx

The binary we need for nand flash are RK3188Loader_miniall.bin and uboot.img.

Flash

refer flash image page

use the new u-boot to erase the old loader

   sudo upgrade_tool ef RK3188Loader_miniall.bin

flash new loader

   sudo upgrade_tool ul RK3188Loader_miniall.bin

format NAND (first time only)

   sudo upgrade_tool lf

flash parameter

   upgrade_tool di -p parameter

paramter file

flash U-Boot

   sudo upgrade_tool wl 0x2000 uboot.img
   sudo upgrade_tool rd

flash kernel + ramdisk

   upgrade_tool di -b boot-linux.img

flash root fs

   upgrade_tool di linuxroot rootfs.img

For SD card

Build

Refer install toolchain if you don't have arm-eabi- on your system. Other toolchain(Linaro arm-linux-gnueabihf-gcc 4.9) may cause data abort errors.

git clone -b u-boot-rk3188-sdcard https://github.com/radxa/u-boot-rockchip.git
cd u-boot-rockchip
make rk30xx
./pack-sd.sh

The binary we need for sdcard is u-boot-sd.img.

Flash

sudo dd if=u-boot-sd.img of=/dev/sdx seek=64

Insert the uSD card to rock pro, it will boot from u-boot on uSD card.
