Hi Matt,

I am aware, that watchdog timer can only be enabled from File Convert settings. I was referring to reset watchdog register. Once the watchdog has been enabled it will count down and then trigger reconfiguration.

I am looking for an option to stop/reset watchdog through the registers. There is a bit 1 in register offset 0x00 (ug_m10_config.pdf) named "reset watchdog timer", but when I set this register MAX10 does reconfigure to a different CFM. I think this is not the correct behavior.

What is the method of stopping watchdog timer without triggering reconfiguration?

Kind regards,

Piotr

Hi Piotr,

The IP register can only reset the watchdog timer. If you want to disable it, you can disable it in File Convert Programming File tools.

May I know how you reset the watchdog using the register? If possible, send me the screenshot of your command or write it down.

Regards,

Shafiq
