ulinkpro -d outputs a jtag-reset about every 5-10 seconds (uvision is not running)

George Weatherford

I started having this problem this morning. I was single stepping through a program when the board reset to start. This continues to happen. I traced it down to the debugger connector pin 15 which is RESET. I stopped uVision, but the reset continues to occur.

Any suggestions?

Thank you,
George Weatherford

    It turns out that the connector made to connect the debugger to the board has a problem. Using another connector alleviates the problem. It seems that both J-TAG and SWD connections on the adapter are connected in parallel and that seems to cause the reset. Using the adapter I get reset pulses coming in the J-TAG reset line.

    Thank you very much for your help,
