Xiang, Thanks for your responses. I'm still trying to get my head around OpenAMP, RPMSG and RPTUN.
I see RPMSG mentioned almost everywhere OpenAMP is discussed; however, no mention of RPTUN. Is RPTUN something unique to Nuttx or is it actually part of OpenAMP? I've already got M7-A53 communication hacked-in-but-working using NXP's RPMSG-lite. I believe all I need beyond what I have is to make the interface look like a bi-directional serial port in Nuttx, so I'm not sure I need RPTUN. Or maybe I'm just not getting it and RPTUN is a layer below RPMSG??? Ed
