IPCF kernel panic

[Quentin2022]

Hi NXP:

hardware:s32g399

ipcf branch:bsp32.0

I downloaded the ipcf code from source codeaurora.Then I built the code with reference to readnme.but when i   insmod ipc-shm-sample.ko,then there was the kernel panic.

Hi,

We assume you are trying to run the IPCF example provided from NXP. Have you done the u-boot configurations explained in the "description.txt" provided in the example?

Please, let us know.

[Quentin2022]

Hi,

The uboot is not configurations .

I have a question, do I have to start M core to run sample on linux? I just want to see if I can run on linux, I don't care if I can communicate with M core.

[Quentin2022]

Hi,

I disable dcach and cleare sram.then i can run sample in linux.

very thanks.

[Daniel-Aguirre]

Hi,

Good to know you got it working.

Regards

I tried to use ipcf_shem_us, but it also failed, and kernel panic occurred. Also used is a branch of bsp32, which is version-dependent or other dependent. I refer to readme build.
