Wow, these RISC-V devices getting more and more interesting :-) This tiny and inexpensive board would be probably better suited for NuttX RTOS that is tiny Unix for MCU.. even if you made FreeBSD kernel work on it then what other apps would fit? https://nuttx.apache.org/ > It uses the C906 which willingly violates the RISC-V spec and would need > =E2=80=9Cerrata=E2=80=9D handling to work, aside from the memory question= . Jess, what are the violations and their impact? What are mitigations? Compiler level? Thanks :-) Tomek --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
