Hi Tomek, I know that the .elf files and fixup4.dat are necessary for initializing the GPU firmware, although some of the other device tree files may be unnecessary. I didn't try experimenting with removing any of them or looking into it to much; my experience with the Pi 4B is that both Raspber

You're right, the Pi Compute Module 4 does use the same BCM2711 chip! I would imagine that you could currently boot NuttX on it with minimal modifications to the RPi4B code. Any drivers for the BCM2711 chip, like UART, I2C, etc. should all work for it as well. I know that it has an accompanying I

Hi Tomek, Although some of the specs between the two boards are similar, the Pi Zero 2W uses the RP3A0 chip from what I can tell, while the Raspberry Pi 4B uses the BCM2711. The RP3A0 uses the same silicon die from the BCM2837. I don't think the code will work on both, although they are both qua

Hello everyone, Yesterday my PR was merged to add preliminary support for the BCM2711 chip and Raspberry Pi 4B board. You can take a look here if you'd like to see the changes: https://github.com/apache/nuttx/pull/15188 Thanks again to all the reviewers who helped me learn some of the build pro
