Reset and Updated Cortex-M4 from Cortex-A

hfranco — Mon, 04 Jul 2022 19:56:26 GMT

Dear support,

I have an iMX8QXP and I'm running FreeRTOS on Cortex-M4F.

I need to update my FreeRTOS code without rebooting the Cortex-A. Is there a way to do that? Update the code of the Cortex-M4F and reset the M4 from the Cortex-A running Linux?
Any thoughts?

Best regards.

Hello,

Yes, this may be possible using the remoteproc framework.

Please refer to the following app note:
