Hello, @ashwini2024 

Thanks for the reply.

By default, the IPCF modules for running on A53 side are already built and put in the rootfs of the pre-built images, when flashing the default pre-built images to the SD card to boot the system, the IPCF modules could be found on the board.

In the BSP40 pre-built rootfs, the IPCF modules are built from IPCF 4.9 by default, means that if you are using IPCF4.9 on M core side, then on A53 side, you may not need to build the IPCF modules yourself, but using the default one in the rootfs.

Since you are working with IPCF4.10, from A53 side, you may have to compile the IPCF 4.10 modules manually, then copy the modules built to the rootfs and insmod them.

Best Regards

Hello, @ashwini2024 

Thanks for the feedback.

From the logs, seems the modules and kernel are not matched, I suggest re-build the modules first(point to the kernel sources that will use), then rebuild the kernel, boot the board with the newly built kernel image and IPCF modules, then to have a try.

Note that do not use the default IPCF modules from the pre-built images, since it is 4.9, not 4.10.

Best Regards

do not use the default IPCF modules from the pre-built images, since it is 4.9, not 4.10. What does this mean ? can u give an explanation on the same? What am i supposed to use if not the pre built images?

[chenyin_h]

Thanks for the questions.

May I know which version BSP you are using for the test? How the modules generated? By Yocto or built yourselves?

Best Regards

Chenyin
