NXP : i.MXRT1170 : RPmsg (or any kind of inter-core comm) support

[mtitinger]

Hello community,

while doing a quick browsing of the sources, I saw support for RPmsg, but I'd couldn't see use of the Messaging Unit IP in the case of RT1170. I would appreciate some input regarding inter-core comm with the i.MXRT platform with Zephyr, what would be the way to go in Zephyr currently : generic RPmsg implem, hand-crafted MU scheme ? Anyone with feedback with this ?

Thanks and Regards,
Marc.

Hi @mtitinger ,
The i.MX RT multi-core MCUs use OpenAMP for the inter-core communication, which uses the RPmsg protocol. On the i.MX RT1170 and RT1160 families, OpenAMP does leverage the Messaging Unit hardware. OpenAMP is tested on these platforms using the OpenAMP sample. And the MIMXRT1170-EVK board page includes details on Building a Dual-Core Image.

I hope that helps, best regards
