Hello Joseph, Not yet... NuttX supports the ARM64 processor (see, for example, the port to PinePhone), but does not support the RPi 4 *yet* because no one has written the necessary board support for it yet. This is a platform that I would very much like to see NuttX running on, specifically the RPi CM4 (Raspberry Pi Compute Model 4), as that seems like a perfect and very powerful processor for real-time embedded applications. Currently, use of a RPi CM4 requires a full-blown OS like FreeBSD or Linux, with all the goodies they include but also with all the overhead, and perhaps more importantly, without real-time. (I tried and wasn't successful getting a Linux kernel built with the real time patch set for this processor.) Cheers, Nathan
