Hi TI

We followed instructions in this FAQ.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1283237/faq-am64x-am62x-how-to-reset-the-soc-when-wdt-timer-expires-in-am64x-and-am62x#:~:text=Set%20the%2017th%20bit%20of,SoC%20by%20the%20ESM%20module

But our board can not get reset. We are sure that timer interrupt has been triggered , our configuration is as below.

After triggered, am2432 no longger runs as we no longer seen the cyclic prints added in our task code. But it can not reset, can you help us for this issue, looking forward to your reply. Thanks.

Hello Anil

We have passed the test now. Root cause is that we have integrated a custom flash which need to be reset before warm reset triggerred or system will not correctlly read out sbl firmware. Thanks.

Hello Cheng guo,

Thanks for the above details, there is no problem with the above FAQ and SOC gets reset after the watchdog expires.
