nrf5340 IPC issue after upgrading to 2.0.0

[mnvcsUDT]

Hello,

After upgrading to the new version with the help of the migration guide, there is an issue that I could not trace back to any changes. 

/opt/zephyr-sdk-0.14.1/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.bfd: zephyr/libzephyr.a(ipc_rpmsg_static_vrings.c.obj):(.data.backend_config_0+0xc): undefined reference to `__device_dts_ord_25'
/opt/zephyr-sdk-0.14.1/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.bfd: zephyr/libzephyr.a(ipc_rpmsg_static_vrings.c.obj):(.data.backend_config_0+0x14): undefined reference to `__device_dts_ord_25'

If I am correct its about the device-tree generation of the IPC.

Any help or pointer is appreciated.

Hello

What is the application you are trying to compile? I assume it's your own application and not a sample?

Are you doing anything out of the ordinary with the IPC? Have you added anything special to the devicetree?

Best regards,

Einar

Thanks for the quick reply Einar. 

It is a custom application with some special leftover in the overlay file indeed.

Removing it fixed the issue.
