Re: [Openamp-rp] Sniffing on OpenAMP/rpmsg Communication

This has so far resulted in various hacks. In my case this all revolves around the Linux kernel, so looking at prior art usbmon comes to mind. But I've so far fulfilled my needs before reaching a point where my prototypes for something like this could be reused. > Wireshark has been used in used for all sorts of communication > protocols and I believe it is applicable here as well.

So I don't think it's a bad idea to reuse what they have - and usbmon shows up in this context again. Regards, Bjorn

Re: [Openamp-rp] Sniffing on OpenAMP/rpmsg Communication

by Ed Mooring

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.

Sniffing on OpenAMP/rpmsg Communication

by Hannes Tschofenig

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 Hannes IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
