Dear Sir/Madam,
I am facing an issue with TC387 startup in EV Board. The problem is, 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.
Could you please clarify me that what possibly goes wrong on Power OFF and ON without Debugger attached? Is there any configuration which I am missing?
NOTE: Valid BMHD is programmed.
Thanks and Regards
Goutham

Hi UC_Wrangler,
The issue got resolved.
Previously I had serviced only CPU watchdog hence the issue remained unresolved.
After servicing of both CPU and Safety Watchdogs , the issue of power on reset got resolved.
With Regards

Hi Goutham. The most common cause for this type of problem is that by default, the watchdog system is suspended when a debugger is connected. Your code may not be servicing / disabling the watchdog.
Try debugging with SYStem.Option.WDTSUS OFF. See this post:

Hi UC_Wrangler,
Thanks for your reply .
As I said earlier, there are no issues when we are using debugger.
We want to test our code in standalone mode (without debugger).
Are there any additional Power On Reset settings/configurations to be done ?
Thanks and Regards

Hi Goutham. I understand there are no issues with the debugger - and that may because the watchdogs are disabled. Please try SYStem.Option.WDTSUS OFF and let us know if your application still works with the debugger connected.
If the application stops working in the debugger, then your application needs to either service or disable the watchdogs.

Hi UC_wrangler,
I tried making SYStem.Option.WDTSUS OFF and the application is still working with the debugger connected.

Hi Goutham. Thanks for ruling that out.
Next: can you post the content of your UCB_BMHD0_ORIG at 0xAF400000-0xAF4001FF? Also, what value is in DMU_HF_CONFIRM0?

Hi UC_wrangler,
I have sent the reply with the contents of UCB_BMHD0_ORIG and DMU_HF_CONFIRM0.
But this forum is not allowing me to do so as the information is sensitive.
It is showing the message " Thank you for posting! Your post will not be visible until a moderator has approved it for posting."
