Hi Alan, I2C still needs some work unfortunately. However, I agree with you generally. Personally, I think HDMI, networking (including WiFi and BLE) and some kind of interaction with storage (eMMC or SD card) are the most important. Unfortunately, those are likely going to be the most difficult because of the lack of documentation on the peripherals. It is definitely not an impossible task, but it will be challenging. Hence my request for creating the new project roadmap, so maybe some discoveries can be documented there and more eyes can get on the RPi implementation.
I may go ahead and start the initial project layout shortly to get some tasks open. Let me know what you think once you get a chance to try NuttX on it! Matteo On Tue, Aug 26, 2025 at 3:58 PM Alan C.
