UCD3138: DEBUG WITH CCS V10

Part Number: UCD3138

Hi team

Our customer is evaluating UCD3138EVM and they encountered some issues when it works with CCS. JTAG via XDS100V3 link is OK, and when they click debug button, the failure is as below:

I notice that most of customers are using Device GUI instead of CCS, do you have any insights about this issue?

    Shaofeng, we usually recommend customer to use Device GUI(pmbus) for downloading and debugging. One advantage to use device gui for debugging is that it's debugging while the code is running. It doesn't need to halt the cpu. But for JTAG, it's requires a cpu halt, which is not good for some topologies.

    Back to the JTAG, when you say "JTAG via XDS100V3 link is OK", do you mean the "test connection" is OK? If so, have you enabled the JTAG function in the code?

    BR,
