As title, I made two boards base on ARM64 MPU with source code providinng, Yocto/Android/Ubuntu can be download available, I believe the hardware spec. almost the same in the market, but my features is provide a LTS OS at least upgrade five years, and add more new function to latest version, my target is create a group, we can use the same hardware and BSP, improve the self skills and project using the same hardware together! BTW, I also have an online service can ask technical question.
