Part Number: TMS320F28388D

Hello Experts,

Here is my scenario.

I have enabled Internal Watchdog in Core1 and Core 2.

With a custom interface, I am able to create a scenario for the software to stop watchdog Refresh pulse in Core 1.

I see the software does not come back.

However, when I have enabled only Core 1 watchdog and repeat the test. The build comes back.

Any suggestions are welcome.

Hi Mohan,

What do you mean it does not come back? Do you mean after reset your code does not restart ?Since you are only letting CPU1 watchdog to timeout and issue reset, CPU2 watchdog should not matter because that is not even timing out. Right? Can you only enable CPU2 (Core2) watchdog and see what happens ?

Hi Vivek,

It was a compilation issue.

The code compiled even though the Watchdog reset address was not available, we fixed this in the code and not its working
