The Pixhawk 6X-RT is an RT1176. The rptun configuration registers the CM4 as /dev/rptun/cm4 from the board bring-up with the TCM memory map the LMEM backdoor window allows, maps the shared window non-cacheable and loads the CM4 ELF on rptun start. The image comes from the SD card (CONFIG_FMU_V6XRT_CM4_FIRMWARE) or, with CONFIG_FMU_V6XRT_CM4_ROMFS, from the etc ROMFS built from src/etc/cm4.elf, so no card is needed. The nsh rptun builtin starts and stops the core and rpmsg ping /dev/rpmsg/cm4 exercises the link; syslog goes to a RAM log readable with dmesg. The board page documents the configuration and the uploader. Assisted-by: Claude:claude-fable-5-1 Signed-off-by: Lourens Naude <lourens@bearmetal.eu> |
