COCKPIT_A53 picked for IMX8 Quad Max, watchdog keeps resetting

flobro — Tue, 09 Sep 2025 13:45:46 GMT

I have watchdogs enabled originally for all 6 processors active on a Quad Max, then I enabled the COCKPIT_A53 setting in ATF. Now it appears that there is a watchdog triggering if the A72 processors are disabled (at the SCFW level/ not the device tree level).

Any idea how to disable the watchdogs just for the A72 processors?

Hi @flobro!

Thank you for reaching out to NXP Support!

You're absolutely right, to prevent resets caused by the watchdog, it’s necessary to configure it properly within the SCFW as well.

You can download the SCFW source code from the link below, based on the BSP version you're using:

Embedded Linux for i.MX Applications Processors

Once downloaded, run the binary file located in the packages folder to extract the source code and documentation for SCFW.

Best regards,
Chavira
