Hello, the Ky X1 is actually the modified version of SpacemiT K1 sold out of China. The deepin-ports SIG provides images for K1, so adapting it for the Ky X1 should be straightforward.
However, the main issue at present is that we don't have any Ky X1 devices available.

You can use K1 images directly: https://deepin-community.github.io/sig-deepin-ports/images/riscv64

This may allows the OrangePi RV2 to operate under the K1 kernel (unverified):
