Part Number: TMS320F28379D Tool/software: Hello, I have a working XDS200, which is able to connect and debug a TMS320F28355. Also, it worked with a TMS320F28379D control card until several weeks ago. Since then I have been using the TMS320F2837D control card's XDS100v2. I have tried several cables to get it work. Also, I measured 3.3V on the XDS200's VCC pin. The results from Test Connection and Debug Connection are shown below. Stephen Debug Connection: Test Connection: [Start: Texas Instruments XDS2xx USB Debug Probe_0] Execute the command: %ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity [Result] -----[Print the board config pathname(s)]------------------------------------ C:\Users\s1\AppData\Local\TEXASI~1\ CCS\ccs1210\0\0\BrdDat\testBoard.dat -----[Print the reset-command software log-file]----------------------------- This utility has selected a 560/2xx-class product. This utility will load the program 'xds2xxu.out'. E_RPCENV_IO_ERROR(-6) No connection Failed to open i/o connection (xds2xxu:0) An error occurred while soft opening the controller. -----[An error has occurred and this utility has aborted]-------------------- This error is generated by TI's USCIF driver or utilities. The value is '-250' (0xffffff06). The title is 'SC_ERR_ECOM_EMUNAME'. The explanation is: An attempt to access the debug probe via USCIF ECOM has failed.
