Hi Hannes, Unfortunately, I don’t believe there is any way to use Wireshark here. Wireshark depends on the underlying protocol stack to provide user-space access to the communication. There are no such hooks in the Linux kernel remoteproc implementation.

It does sound like a cool idea though.

Hi all,

This might be a stupid question but I try it anyway.

I would like to use Wireshark to capture the communication over the OpenAMP/rpmsg stack from one processor to the other one.

Wireshark has been used in used for all sorts of communication protocols and I believe it is applicable here as well. I could imagine that someone wrote such a Wireshark plugin already. Maybe someone of you knows. This could be useful for debugging.

Ciao
