CCS/AM5708: Cannot Access DAP

Part Number: AM5708

Tool/software: Code Composer Studio

On my custom AM5708 board, I have two target configurations. One works and the other one doesn't.

The error I get from one configuration is this :

According to JTAG debug wiki [1], this could be hardware issue. Hence I am compelled to get to the bottom of this even though my 2nd configuration seems to work ok.

As the message suggest, I slowed down the JTAG speed as well. It doesn't help.

Can someone think of what may have resulted in this error? I can't tell the difference between my two configurations.

  • Hi,

    What do you exactly mean by two "Target Configurations"? Are they two target configuration files, different Debug Probes or different boards?

    If the files, then would you mind attaching them so I could try to see if there are any changes?

    Regards,
