After enabling CONFIG_SHELL=y And CONFIG_SHELL_BACKEND_RPMSG=y in prj.conf, I get the Flash overflow error

[neuberfran]

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)

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:

Some questions:

• Where is your "flash" located?
• Why do you build for 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?
