iMX8ULP: M33 and A35 independent reboot

texnikk — Mon, 21 Oct 2024 19:37:37 GMT

In the M33 examples, it appears that the A35 can be rebooted independently from the M33 core.

Question: Is it possible to reboot the M33 core independently while the A35 core continues running, without triggering a full system reset?

Hello @texnikk

For the Cortex-M is a bit complicated as in this processor (i.MX8ULP) the Cortex-M is in an always on state, cannot be turned off, while the Cortex-A is still running.

Best regards,

Salas.

Hi @Manuel_Salas , could you please help with answers to additional reboot-related questions:

- How to correctly reboot M33 Kernel, when A35 Kernel reboots from linux or uboot ?
- How to correctly reboot M33 kernel at any moment?

Thank you in advance,

Sergey
