Thank you Greg for the reference point! :-) I bought rPI0-2W as only the 2W variant has support for 64-bit OS and supports running FreeBSD.. this is second generation of rPI0 (and uses different SoC than predecessor rPI0 or rPI0-W/WH).. but there is a problem with DTS files that needs to be by-hand updated with specific setup and specific versions.. so I did not even manage to run this board yet on a quick 5 minutes check from a GENERIC pre-built FreeBSD image.. thus my question to Matteo on DTS files experiences mine are poor :D I found these sites useful for comparison of models and rPI CPUs: 1. https://www.raspberrypi.com/documentation/computers/processors.html 2. https://raspians.com/raspberry-pi-models-comparison/ It seems this rPI0-2W is closer to rPI3 rather than rPI4. Anyways it is very nice to see NuttX going step by step towards big CPU/SoC like ARM Cortex-A and RISC-V RV64 :-) The common problem with all those modern SoC are the low-level peripheral drivers - vendors does not really seem to care to provide OS/RTOS agnostic license free drivers that could be easily integrated to different projects so each OS/RTOS need to develop their own code from scratch.. -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
