Remi Pi is a compact, low-cost SBC powered by a Renesas RZ/G2L Cortex-A55/M33 SoC
MYiR Tech provides a Linux 5.10.83-based image built with the Yocto Project and plans to release Ubuntu and Debian images soon along with open-source drivers. Usually, they only do that for their paying customers, but the Yocto image for the Remi Pi, some documents, and source code can be downloaded directly on the MYiR website. Chinese readers may also access a support forum that looks to be somewhat active.
