Build System Images:

1. Build u-boot & kernel:

./build-base.sh

2. Build minimal Debian system image, output image: deploy/rk3568-mixtile-edge2-debian-minimal.img.gz

sudo ./build-image-debian-minimal.sh

3. Build full-size Debian system image, output image: deploy/rk3568-mixtile-edge2-debian-full.img.gz

sudo ./build-image-debian-full.sh

4. Build minimal Ubuntu system image, output image: deploy/rk3568-mixtile-edge2-ubuntu-minimal.img.gz

sudo ./build-image-ubuntu-minimal.sh

5. Build full-size Ubuntu system image, output image: deploy/rk3568-mixtile-edge2-ubuntu-full.img.gz

sudo ./build-image-ubuntu-full.sh

System image should be uncompressed by xz before being installed to device.

Prepare upgrade tool:

git clone https://github.com/rockchip-linux/rkdeveloptool.git
cd rkdeveloptool
sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf
aclocal
autoreconf -i
autoheader
automake --add-missing
./configure
make

Install system image to device:

wget https://downloads.mixtile.com/edge2/MiniLoaderAll.bin
sudo ./rkdeveloptool db MiniLoaderAll.bin
sudo ./rkdeveloptool wl 0 system.img #Replace system.img to the uncompressed system image you get.
sudo ./rkdeveloptool rd
