TMS570LC4357: Using CCS7.3 to debug code

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Code is being developed on a 4357 Development board, used for many different projects.

Having been using your sample code from HALCoGen to exercise DMA-controlled SCI transfers (which seems to have its own problems), I tried to start a debug session but did it in a different way to usual, namely right-clicking the project and hitting Debug As. Normally I would open the Debug Configurations and check all was set properly.

During the Erase cycle, the process hung up. I eventually unplugged the USB cable, then power. It happened a second time. From then on, despite a full re-boot, the Debug Configuration screen shows

" [Program]: Specified Program ( Texas Instruments XDS100v2 USB Debug Probe_0/CortexR4 )  does not exist". Incidentally, the 4357 shows as a Cortex R5.

Presumably a driver has been corrupted, even though doing a Test Connection for the Target Config runs fine. What to do?

Using another PC, with CCS7.0, a different project loaded fine, but I can't swap projects between PCs.

Thanks
