Ashima,

The explanation of this error together with some possible workarounds is shown at the following reference:

software-dl.ti.com/.../ccsv7_debugging_jtag_connectivity_issues.html

I will also move this thread to the C2000 forum in case the experts there have some additional insights specifically with regards to this F28377S Launchpad.

HI there Ashima,

D7 and D8 are LEDs that indicate Debugger Activity of the XDS100.

Please work through the JTAG Connectivity references AartiG replied with, and if you are still concerned with the LP, Please post a reply.

Thanks Mark and Arti. But the forum issues you have refereed to is from the starting of the programme. However for this case, controller was working fine till the power circuit is not switched on. The moment power circuit is switched on error is shown and d7 and d8 starts glowing.

Also, the pwm of controller and power circuit is isolated. So there is no chance that the controller is affected from power circuit.

Thanks Mark. I had adjusted the plates on JP1 and JP2 and now its working fine. Thanks a lot.

Ashima,

Did you place the shunt on JP1 and JP2, or did you remove it to make it work?

-Mark

I think it was bit displaced so i just pressed it on the same place.

Ok. Great. Please don't hesitate to create a new thread in the future if you ever encounter more issues!
