Dear Team

My TC38x ECU is not running after Disconnecting debugger and doing POWER ON RESET.

Could you please let me know how to disable the Safety and CPU Watchdogs 

Any API's available ?

Hi Sreemanthula,

I hope you are using IFX iLLD. If yes, You may use the IfxScuWdt_disableCpuWatchdog & IfxScuWdt_disableSafetyWatchdog APIs for disabling the CPU & Safety Watchdog.

It is possible that the issue could be because of not servicing the CPU & Safety Watchdogs if they are enabled. You must ensure that Servicing is done periodically if both the Watchdogs are enabled.

Hi,

If you're not using the IFX iLLD then the above APIs are not directly applicable. But as mentioned before you must ensure that the Watchdogs are either disabled or serviced periodically if enabled.
