S32G IPCF driver

piaochunri — Wed, 11 Sep 2024 11:09:14 GMT

Hi experts,

I was debugging ipcf of A core in S32G399A and my bsp version is 41.0.Which version of ipc-shm should I choose?Thank you!

Hello, @piaochunri

Thanks for your post.

The latest version of IPCF is 4.10, which is compatible with BSP40 according to the release notes, I suggest using the BSP40 for your test instead of BSP41(since it may be not fully tested and verified with BSP41).

Sorry for your inconvenience.

Thank you !

And I have tried it according to your suggestions.I used bsp of version 40.0 and I downloaded the latest version of IPCF of version 4.10.Then I copied ipc-shm-dev.ko and ipc-shm-sample.ko into the self-developed board.And I ran the ko files.It seemed ok when I ran ipc-shm-dev.ko but got errors when I ran ipc-shm-sample.ko.The log is as follows.Could you get something wrong?Thank you!

Hello, @piaochunri

Thanks for the reply.

May I know if your ipc-shm-dev.ko and ipc-shm-sample.ko are compiled manually from the 4.10 code?

Hi, @piaochunri

Seems this thread is similar to the other thread that my colleague already handled, then let's temporaly focus on that thread.

Thanks
