Hello Niteesh, from a quick look there are the following drivers: - Serial - GPIO - I2C - SPI - Some Framebuffer In 2016 a GSoC student tried to port the USB and Ethernet driver. But it seems that this work hadn't been merged: https://devel.rtems.org/wiki/GSoC/2016 Regarding good starting points: I think you already found some with just this mail. - If you have an old Pi1 or 2, you could try to run some basic RTEMS there as a first step. Or did you already try that? - You say that it "should work" on RPi3 and RPi4. It would be great if you could try it and update the documentation if it does. - If you take some notes while doing the tests, it would be great if you could donate them to the documentation so the old README could be replaced: https://docs.rtems.org/branches/master/user/bsps/bsps-arm.html#raspberrypi - If you want to start a bigger project you could take a look at the USB work and test it. Most likely it still needs some work. - If you are interested in any other peripheral of the Pi: Just ask.
