RTEMS for RED-V board

[Pierre FICHEUX]

Hi Lou,

Thx for your answer, I know that link. AFAIK Zephyr or FreedomStudio use a
different approach as a header file is generated from the .dts and then
used to create the binary (.bin then .hex). It looks like the binary is
"standalone" with no use of a bootloader (RED-V includes a Segger firmware
to flash the
board)...but I'm far from a RISC-V/SiFive expert :-)

https://docs.zephyrproject.org/latest/guides/dts/intro.html#input-and-output-files

regards
