Below is the instructions of how to build image for ROCK960.
You need a type C to type A cable(USB 2.0 or USB 3.0) to flash ROCK960.
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
sudo apt-get install gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev build-essential libssl-dev
./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/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
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 .
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
