ULINK2 JTAG COMMUNICATION FAILURE

lafaz om

Dear Forum members,

I have purchased Keil ULIN2 adapter yesterday. I am facing problem JTAG COMMUNICATION FAILURE When I am trying to flash download or erase.

I have tried with different clock settings 50, 100,200,500, and RTCK. But same problem remaining... :-(

Could any keil ARM experts help me to fix this problem.

Thanks & Regards

    Hi,
    1. I also had communication failures caused by a damaged JTAG cable.

    2. Do you have another hardware to test the debugger with? Maybe an evaluation board of the same or another controller?

    3. What happens, when you try to debug (not flashing) e.g. an example project?

    4. Go to "target options" -> "Debug" select ULINK ARM Debugger and click "settings".
    Does the debugger recognise a device?
    Is the ID code equal to the ID you expect (see datasheet of controller)?
