Hi,

I'm working on a IPCF_Example_S32G274_M7_0. I am following the description.txt file (attached below) provided by NXP.

getting error : ERROR: could not insert module /lib/modules/5.10.109-rt65+g0bace7fde5f5/extra/ipc-shm-sample.ko: Address already in use

Hi,

Are you using a modified version of the NXP BSP? We have found bugs under the BSP33.0 release with the IPCF package, seems there was a problem when building it. AN13750 available under the S32G2 product page (link: S32G2 Safe and Secure Vehicle Network Processor | NXP Semiconductors) shows the building of the IPCF package for BSP33.0, this provided us with an IPCF working package under BSP33.0.

Another recommendation, if feasible, is moving to BSP35.0, which we have confirmed that IPCF package is working as the example expects.

Solved: Re: Problem: S32R45 IPCF insmod ipc-shm-sample.ko ... - NXP Community

It is a different platform, but the BSP is shared and share the same concept.

Please, let us know.
