I have trouble loading bare-metal programs to OSD335x using XDS200 JTAG debugger. What should I do?


Generally, XDS200 connectivity issues can be resolved by updating its firmware.

To update a XDS200-class JTAG debugger connected via USB, using a Windows host is highly recommended. Close any instances of CCS that are running in your system. Open a Windows Command Prompt and issue the following commands:

1. Go to the directory where the utility is installed:

C:\>cd C:\ti\ccsv6\ccs_base\common\uscif\xds2xx

2. Run the configuration just to make sure a XDS200-class debugger is connected and to confirm the firmware revision installed on it:

C:\ti\ccsv6\ccs_base\common\uscif\xds2xx>xds2xx_conf get xds2xxu 0

3. If you have a single XDS200 connected via USB:

Run the following commands in the exact order shown below (the batch file update_xds2xx does this in reverse order, increasing the chances of failure):

C:\ti\ccsv6\ccs_base\common\uscif\xds2xx>xds2xx_conf update xds2xxu 0 xds200_firmware_v1008.bin
C:\ti\ccsv6\ccs_base\common\uscif\xds2xx>xds2xx_conf program xds2xxu 0 xds200_cpld_v1008.xsvf
C:\ti\ccsv6\ccs_base\common\uscif\xds2xx>xds2xx_conf boot xds2xxu 0

4. After that, run the command in step 2 again to check if the correct firmware was loaded.

C:\ti\ccsv6\ccs_base\common\uscif\xds2xx>xds2xx_conf get xds2xxu 0


If connectivity issues persist, please go through the XDS200 Wiki to find out more information.
