AN13750 IPCF insmod error

LB666 — Tue, 02 Apr 2024 06:18:04 GMT

Hello, I refer to the document AN13750 to build a multi-core boot program that can run on the S32G-VNP-RDB2 development board. However, when I run it on our self-designed board, I execute the following command: insmod ipc shm sample_multi instance. ko;

The following error message appears:

Hello, @LB666

Thanks for the question.

I understand that you are running with the IPCF 4.6 samples following AN13750, and it works fine from your side to run it on RDB2, is it right?

But the same code triggered the error from your custom board?

Best Regards
