Even though the port is limited by driver support right now, I still think this is a huge step forward for NuttX. Also, I have a project that is using Linux on a Raspberry Pi Compute Module 4, which I think uses the same chip and shares much of the same hardware. Not sure how similar they are but if I could use NuttX instead of Linux there, it would be a tremendous improvement in reducing complexity. I can't wait to try... Thanks again, and I hope this inspires others to get involved in this port, and ports to other popular Pi models... Cheers, Nathan
