I added the following debug line:

        }

And this is what I got after issuing a 'reboot' command in Linux:

# reboot

Any ideas as to why CMD_ERR bit is being set in the irqstat register?

Thanks

Do you enable M4 partition in your image?

I haven't done anything with regards to the M4 partition.

What should I do exactly?

Thanks

Ok, then I think you not have M4 used.
Which kernel are you using? Which SCFW/SECO?

What needs to be done in order to use the M4?

> Which kernel are you using? Which SCFW/SECO?

I am using kernel 5.6.2.

SCFW is imx-sc-firmware-1.2.7.1
SECO is imx-seco-2.3.1

If I use the NXP U-Boot from the imx_4.19.35_1.1.0 BSP the reboot works fine.

Any suggestions?

Thanks
