I am not a prefessional developer, more a casual programmer, so working with large frameworks in a casual manner is a nightmare. NuttX seems to have a much more structured interior than the ESP-IDF and I was really positively surprised about the fact that "make" is supported (I have hard times with cmake and its concept). Is there an intriduction for NuttX beginners on FreeBSD in special or in common for the various architectures you know of and willing to share? I abandonded esp32 architecture for now since the port provided in the official FreeBSD tree is LX6/LX7 only (no RISCV32) and the port found on github (search for trmobik esp32) is fragile and broken on recent 15-STABLE and CURRENT (I use those for other reasons).
