- Where is your "flash" located?

sysbuild? - How do you load the firmware?

Why do you build for sysbuild? I still don't know, but I always used this tag
How do you load the firmware? https://www.youtube.com/watch?v=V06RC2G_3M8&t=35s
I load zephyr.bin in U-boot. After Linux starts I use the echo stop command (from remoteproc) to stop zephyr.bin and I use echo start to start zephyr.elf inside the Linux UserSpace
Where is your "flash" located?

zephyr,flash = &ocram_code;
//zephyr,flash = &tcml_code;

I'm still getting the error:

Hi,
I stay trying this: https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/ipc/openamp_rsc_table in my imx7d-pico (m4 side, board in zephyr = pico_pi_m4)
https://github.com/zephyrproject-rtos/zephyr/issues/69433#issuecomment-2016598955 https://www.youtube.com/watch?v=V06RC2G_3M8
I'm migrating from Version 3.4 of Zephyr to 3.6.99 so I can access /dev/ttyRPMSG via Linux/Yocto through minicom -D /dev/ttyRPMSG0. Unsuccessful because I need to implement CONFIG_SHELL=y And CONFIG_SHELL_BACKEND_RPMSG=y (Note: Without these two options above, I have no errors, but of course, I don`t have shell)
When I enable these options in my prj.conf I get the following error:
pico_pi_m4.overlay
prj.conf
How can I solve it (Pls)
