RemoteProc in imx7d with (0, err:-62). I don't have /dev/ttyRPMSG. Zephyr openamp_rsc_table example

[neuberfran]

Hi,

https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/ipc/openamp_rsc_table

I have error imx-rproc imx7d-cm4: imx_rproc_kick: failed 101(0, err:-62)  in RemoteProc/openamp_rsc_table/Zephyr Upstream project in m4/pico_pi_m4 (side).

This is my main DTS within the Yocto Kirkstone (referring to the m4):https://gist.github.com/neuberfran/9da2d4a1481b661f8545a5d91ad7761b

My device does not have a debug port, so I want you to list the possible causes of this error, obviously focused on my specific case: Remoteproc in imx7d-pico

E.g.: Look to cat /sys/kernel/debug/remoteproc/remoteproc0/resource_table
