Rockchip Debian SDK

Below is the instructions of how to build image for ROCK960.

Requirement

You need a type C to type A cable(USB 2.0 or USB 3.0) to flash ROCK960.

Get the source code

You need repo to get multiple git repositories to build the image.

Install repo if you don't have it.

mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

sync the source code

repo init -u https://github.com/96rocks/manifests -m rock960.xml
repo sync
repo start rock960-dev --all

You will get

build  kernel  README.md  rkbin  rootfs  u-boot

Install toolchain and other build tools

sudo apt-get install gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev build-essential libssl-dev

Build u-boot

./build/mk-uboot.sh rock960ab     #For model A and mode B
./build/mk-uboot.sh rock960c      #For model C

The generated images will be copied to out/u-boot folder

ls out/u-boot/
idbloader.img  rk3399_loader_v1.08.106.bin  trust.img  uboot.img

Build kernel

./build/mk-kernel.sh rock960ab    #For model A and mode B
./build/mk-kernel.sh rock960c     #For model C

You will get the kernel image and dtb file

ls out/kernel/
Image  rock960-model-ab-linux.dtb rock960-model-c-linux.dtb

Make rootfs image

Building a base debian system by ubuntu-build-service from linaro.

sudo apt-get install binfmt-support qemu-user-static
sudo dpkg -i ubuntu-build-service/packages/*        # ignore the broken dependencies, we will fix it next step
sudo apt-get install -f
RELEASE=stretch TARGET=desktop ARCH=armhf ./mk-base-debian.sh

This will bootstrap a Debian stretch image, you will get a rootfs tarball named linaro-stretch-alip-xxxx.tar.gz.

Building the rk-debain rootfs with debug:

VERSION=debug ARCH=armhf ./mk-rootfs-stretch.sh  && ./mk-image.sh

This will install Rockchip specified packages and hooks on the standard Debian rootfs and generate an ext4 format rootfs image at rootfs/linaro-rootfs.img .

Combine everything into one image

build/mk-image.sh -c rk3399 -t system -r rootfs/linaro-rootfs.img

This will combine u-boot, kernel and rootfs into one image and generate GPT partition table. Output is

out/system.img

Flash the image

Troubleshooting

Can not go to maskrom mode

Press and hold maskrom key longer, and short press and release reset.
Check your usb cable, plug and unplug the usb cable, reverse plug the type C port and try
On the host PC, lsusb should show the following VID/PID if the board is in maskrom mode:

Bus 003 Device 061: ID 2207:0011
