PROCESSOR-SDK-AM57X: IPC version

Part Number: PROCESSOR-SDK-AM57X

Tool/software:

This is a followup to the following question:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1304306/faq-processor-sdk-am57x-what-ipc-version-for-do-i-use-when-using-linux-sdk-08-02-01-00

What exactly changes in the IPC that could cause a mismatch?  If we are using our own message definitions that go across ipc using the rpmsg framework, does that matter.  Maybe its the 16 byte header that could change?  Looking at the repo mentioned in the link it doesn't appear to change a whole lot.

Thanks,

Jason
