View Full Version : TC277TU locked up

Oct 7th, 2014, 07:22 AM
I have an Infineon demonstration board with a TC277TU which was functioning correctly on all 3 cores with an old application.
When I tried a new application the TC277 locked up.
My debugger, a Lauterbach on the nexus port reports "emulation debug port fail" when the "system.Up" command is performed.
I tried the DAS application via the USB port but whenever I try to connect to one of the cores I receive the message "Write failure for a transaction of the txlist".
The previous application no longer functions on this board either.
All combinations of the dip-switches do nothing.

Can anyone explain how the TC277 has been locked up and is there a way of unlocking it please.
