I'm currently having an issues with my custom board trying to connected to a TM4C123BE6PZ. After power up, when I try to connect I get an error -121 bad controller handle. When I retry I get the same issue. If I cancel and try to connect again, I get an error -1170 which is an unable to access the DAP. I continue to get this error on subsequent retries.
Now, I was able to connect up to this processor beforehand and I was able to download the barebones "typical_tivaTM4C123BE6PZ" sample project and inserted a "while(1);" at the start of main. Once I disconnected, I was unable to reconnect. I have tried this with 2 of our custom boards (at least its consistent).
I tried the test connection option and it passed, I can post that if necessary. I looked into using the LM Flash programmer utility, but as I am using a custom board I'm not sure what I should select for the interface for XDS100.
Somewhere else on the board I saw a tip that said to change the Access Port Designator to 0x02000100, but that doesn't seem to make a difference.
Originally, we had a MUX to debug multiple processors on the board, but we have 100% bypassed that and we are still having the same problem.
Another thing I noticed was that the gel file calls out the "cortexM3_util.gel". As its a M4, could this be my problem?
I'm running 6.0.0.00190 and my clock speed is at 80 MHZ.
Thanks in advance,
