    Hi,

    I have a comstick that has an embedded USB that I debug through. I debug through OpenOCD and Hitex. I have a target running that I can halt in either debugger. I have tried the commands halt, reset etc and they have no effect, it keeps on running.

    Does anybody know how to stop my device?

    Many Thanks,

    Tom

    Hi,

    I had similar problem, but different board and same environment.

    I was not able to halt the target and when I issue for first halt command and then poll commnad by the openOCD interface I see:

    target running

    I went through some hardware debug and I saw that my reset generator was broken, it stuck to gnd the reset and I was not able either to run or to debug. I think this happends because when you use a debug cable (wiggler, FLASHLink and so on) there is a net conflict between the reset generator and the Jtag interface that is trying in debug to reset the micro by the reset line.

    Take a look at your hw and check if once the debug cable is plugged in the reset line is moved correctly.

    In my case I removed the reset generator and changed it with an RC net.

    Good luck.

    Marco
