CC2650: XDS110 firmware update does not complete, does not re-enumerate

Part Number: CC2650


Team-

We have a customer that has put the XDS110 tool chain directly onto their board for ease of debug.

When USB is connected, the TIVA processor appears to enumerate properly as a "Stellaris Device Firmware Upgrade":

Following the firmware update instructions, we see that the download of the flash image appears to complete successfully:

We then expect that the device will re-enumerate as the debugger, which is what happens with a launch-pad.

However, we see that Windows 10 re-enumerates, but it just comes up again as the Stellaris Device again.

Clearly we seem to have a good USB connection; do you have any idea what is happening that it seems to revert back to the Stellaris...Upgrade?

Thanks, Best, S. Dunbar, AFA Colorado
