HW watchdog problem

Hi all!

Our application loads binary to the VPSS M3 microcontroller via slaveloader (from sylsink) which starts ( restarts ) the VPSS M3 controller.

During application run the watchdog hardware can reset the system without any problem. But after application close it causes freeze when or after the hardware watchdog tries to restart the system.

We presume that the VPSS M3 does something "terrible" (not in our code) on the end. Binaries has unloaded via slaveloader successfully. The only solution we found is to load the binary back to the VPSS M3 which causes the restart of the processor.

What's should be the problem?

Regards,
Lajos
