Hi @RudolfStreif,
Thank you for your detailed answer, I really appreciate that. This will help on my side as well.
I can see from the link you shared that NXP gave you an answer recently:
I hope you are doing well.
We tried the binaries provided by you.
It worked in u-boot using bootaux command.
We didn't observe any issues with imx8mp_m7_TCM_hello_world.elf and imx8mp_m7_TCM_rpmsg_lite_str_echo_rtos.elf.
It turns out that DDR-mapped elf support is not added to imx_rproc.
It should be mentioned that the NXP is planning to add the same in the future release.
I will first check on my side (and also check the mainline version) before taking any conclusions. For now, we can say that this feature isn’t supported yet.
Best Regards,
Hiago.
