Get the source code

Clone the source code

mkdir ~/rk3588-sdk && cd ~/rk3588-sdk
git clone -b stable-5.10-rock5 https://github.com/radxa/u-boot.git
git clone -b master https://github.com/radxa/rkbin.git

2. flash u-boot to you storage

emmc

sudo dd if=./idbloader.img of=/dev/mmcblk1 bs=512 seek=64
sudo dd if=./u-boot.itb of=/dev/mmcblk1 bs=512 seek=16384

sdcard

sudo dd if=./idbloader.img of=/dev/mmcblk0 bs=512 seek=64
sudo dd if=./u-boot.itb of=/dev/mmcblk0 bs=512 seek=16384
