Part Number: LAUNCHXL-F280039C
We purchased ten LAUNCHXL-F280039C boards, and six of them have an issue with the onboard XDS110 debugger.
When any of these six boards are connected to the PC via USB, the XDS110 is not detected by Windows Device Manager at all. In contrast, the other four boards are detected normally using the same PC, USB cable, and USB port. For the working boards, the XDS110 Class Application/User UART and XDS110 Class Auxiliary Data Port appear immediately in Device Manager.
All six affected boards were being used for the first time when this issue occurred. We tested them under the same conditions as the four working boards, but none of them were detected by the PC.
Has this issue been reported or encountered with the LAUNCHXL-F280039C before? Could you please advise whether there are any troubleshooting procedures or possible solutions we can try to recover the onboard XDS110 debugger?
If the issue cannot be resolved through troubleshooting, could you also help confirm whether this is likely a hardware failure of the onboard XDS110?
I have attached photos showing the Device Manager results for comparison between a working board and an affected board.
Thank you for your assistance.
