Hello, @TrikiIkram
Thanks for your post.
1. Sorry that there is still not a public document for your reference, which would act as a similar reference as AN13750 for S32G3.
2. Currently, I suggest using AN13750 as a reference, not a step-by-step guide for using it on S32G3, for setup the IPCF on S32G3 platform, I suggest directly trying the single instance samples instead of the multi-instance sample, so that you will not need apply the patch mentioned.
