Since the upstream U-Boot started to support Orange Pi 3B since https://github.com/u-boot/u-boot/commit/a52099b4a2ae9e8cafc79268325249bcad308012, I am going too stop maintaining the patches in this repo.

Please refer to the upstream implementation and report bugs to the upstream. Thanks!

U-Boot patched for Orange Pi 3B.

Unlikely Xunlong's U-Boot, this U-Boot is based on the mainline U-Boot, and it is much more up-to-date.

Install dependencies:

1. aarch64-linux-gnu-gcc toolchain
2. gcc toolchain for your host environment

And then:

$ git clone https://github.com/w568w/u-boot-orangepi-3b --recursive
$ cd u-boot-orangepi-3b
$ ./orangepi-3b-build.sh

You only need the built u-boot-rockchip.bin file. # means you need root permission to execute commands:

# dd if=u-boot-rockchip.bin of=<your-sd-card> seek=64
# sync

Also check U-Boot's documentation about Rockchip.

Okay, you can keep up with the mainline by:

$ git remote add upstream https://github.com/u-boot/u-boot
$ git fetch upstream
$ git merge upstream/master

You may need to resolve some conflicts; follow the instructions by Git.
