TMS570LC4357: Cannot connect to Debug Probe XDS110

Part Number: TMS570LC4357


Hello Team,

Context:- I am working on a custom PCB with TMS570LC4357 and a PMIC. I am working to get the PMIC running. I have added code to run the PMIC, the SW was running fine and was able to connect to XDS110.

Issue:- I updated the code and added just a while loop to check for a condition. After flashing this update. I am getting an error when I try to connect to the target.

I verify the connection, The JATG DR and IR Integrity scan-test has succeeded. But I am not able to debug the session anymore. I am getting the below mentioned error code. 

When I press retry, a different Error code is generated.

I have then launched the targetconfig using the .ccxml file. I am able to connect Target with IcePick. When I try to connect Target with Dap. I am getting the same above error codes of 240 and 1170.

I have then tried to change the Connection Properties as shown in below pic and then launched the targetconfig. I still was facing the same issue where I am able to connect Target with IcePick and not with Dap.

Can the team help me in resolving this Issue.

Kind Regards,

Sakti
