Hello community members,

I am facing same issue mentioned in following link, with same setup: https://community.infineon.com/t5/AURIX/AURIX2G-Power-On-Reset-TC387QP-Start-Up-Issue/m-p/319356#M52...

Problem in short: when I connect the device with Lauterbach and flash my Hex/Sre/Elf File, it works properly. But when I de-attach the Lauterbach JTAG, my Application/Software does not run after Power OFF and On.

Solution of this thread suggested servicing the both watchdog has resolved the problem but in my case it is not working after that as well. 

Watchdog code:

Hi,

For test purposes, can you try disabling the watchdogs and check the behavior?

Best Regards.

Firstly I did the test by disabling the watchdogs then I got the above issue so I started looking for resolution and found that I need to add + serve the both watchdogs. But still issue is not resolved. I thinking it might be the issue of reset handling mechanism, in current software we did not add PMS or reset handling , what would be your suggestion?
