How to read from CAN through M4?

Felice — Fri, 07 Jul 2023 12:48:41 GMT

Hi all,

I'm currently using AAOS version 13.1.0_1.1.0 on my i.MX 8QuadMax MEK and I'm interested in using M4 to read from CAN and then communicate to the application processor through rpmsg.

I have read from some threads on the community that some steps are performed by default and some are not. Is it possible to have references about scfw, M4 firmware and RPMsg enabling state?

Thank you for your support.

Regards.

Hello,

since I'm also interested in the subject, I looked into the page you linked and I noticed it refers to FlexCan on A-core.

Is there any reference about working with FlexCan on M4-core instead?

Thank you.

Regards

Hi,

unfortunately, the document that you shared didn't help me because it refers to A cores.

Thanks anyway.
