I’m just beginning with 32-bit arm assembly, and it would be nice to run my tutorial programs on it. I don’t even know where to start, though.
I have not looked into this yet, but the keyword is
remoteproc, also here is some interesting stuff suggesting it is possible:
Also somewhere in iMX8MQ reference manual I found mentioning that one of the UART ports (UART4) could be assigned directly to M4F core (eg not through the bus and periphery mapping but at boot time). I didn’t find details about it though, perhaps needs some eFuses.
