I don’t know if it will work for anyone else. I put this together yesterday.

It’s based on the native toolchain, so it may need some libraries installed as per the Kendryte-gnu-toolchain installation instructions. Or it may not work at all for others.
I have used it on my RPi3 and Jetson nano so far to build, upload and run some example sketches.
