I can not perform a SW reset using the Demo application provided, although it is working on Tc38x.
The only difference between the two controllers is the UCB, as the TC387's UCB that works with the SW reset is updated with the DemoApp UCB data, but TC377's UCB, which does not work with SW reset (Hang after the reset), is not updated.

I tried it on two different controllers (TC377 and TC375) with the same not working behavior, as it totally hangs without the possibility of stoping the controller using the debugger.
If the UCB is somehow related, can I know the possible reasons, please?

Thanks,

Is there any of the BMHD UCBs programmed on TC377? How you make your tests, with debugger connected? Which debugger, if used?

No there are no BMHD UCBs programmed on TC377. Can I know what is the relation between SW reset and UCB, please?
I test it by the serial interface provided by Demo Application. It can multiple demos and I am selecting one of the demos, which in this case the hardware reset.
I am using the iSystems debugger.

After an application reset, the system software loads values from the UCBs into various registers for usage in run time. Once this has completed, the system software can complete the start up sequence and move to normal operation.
