AX620E BSP Build

Builds u-boot and linux kernel for Axera AX620Q/AX630C based boards such as NanoKVM-Pro.

Compiling and building yourself

If you do not want to use the prebuilt packages, you can compile yourself.

download source

git clone https://github.com/scpcom/ax620e-bsp-build --depth=1
cd ax620e-bsp-build
git submodule update --init --recursive --depth=1

You can remove the --depth=1 parameter to get full history.

host environment

• OS: Debian 11/Ubuntu 22.04 or higher is recommended
• CPU: AMD/Intel x86_64
• Memory: 8 GB RAM (Required to build opencv tests, all other can be complied with 4GB and below)
• Storage: 30GB free space minimum (plus optional 40GB to compile the toolchain)

On Debian/Ubuntu you can install required packages with:

./scripts/prepare-host.sh

build it

./build.sh

Running

Example how to run on NanoKVM-Pro. Use at your own risk.

Replace the IP 192.168.1.234 with the address of your NanoKVM-Pro.
