I have the P2020RDB development kit, and cannot connect via the USB Tap. I am targeting the QorIQ P2020 processor.
When I hit Debug->Connect, I get a popup box that says, "CCSProtocolPlugin : CCS: Core not supported [Connection refused]".
The CodeWarrior output shows:
"Syntax error at line 10"
"The JTAG chain does not contain any debuggable chores!"
I am running ccs at the same time. It outputs the following:
"CCSAPI connection #1 accepted from localhost.localdomain at Wed Dec 1 13:14:51 2010"
"CCSAPI connection #1 from localhost.localdomain closed at Wed Dec 1 13:14:52 2010"
I have also tried to use the Flash Programmer, but get "Connect failed" and the logs show, "unknown error".
Let me know if there is more information I can supply.
