I am using FreeBSD for Apache NuttX RTOS development, try this one out, supports many different architectures, and is kind of Unix for MCU :-) https://nuttx.apache.org/ List of supported platforms and chips and their peripherals is here: https://nuttx.apache.org/docs/latest/platforms/index.html gcc-arm-embedded compiler is in the ports. If you want to use esp32* chips you can use one from esp-idf I patched it so Linux binaries are installed and works on FreeBSD, plus Espressif has dedicated team for NuttX development (yes esp-idf is a moving target but taken care of by their team here). You can even work with AVR :-) Have fun :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
