CCS/PGA900: The target failed to see a correctly formatted SWD header.

Nathanael Birrer

Part Number: PGA900

Tool/software: Code Composer Studio

When preparing the measurements with a oscilloscope I thought why not using another debugger like the "new" xds110 which is very cheap and has internal power supply and uart to usb bridge.

Surprisingly, I could debug my own board without any troubles! Obviously, the xds200 got a little damaged or has other specifications on SWD than the xds110.

I thought this information might be interesting to some of you.

Hi,

Sorry, I am not entirely sure what is the train of thought of your post. Is your intention to report that PGA devices work with the XDS110 Debug Probe as well? If so, thank you for reinstating that.

The https://www.ti.com/xds110 contains a list of supported devices and we made sure the PGA devices were listed there - after all, it is a less costly alternative to the XDS200.

If you mean to report the issue with the connection, the titile reflects issues between the debug probe and the target device. If you mean the XDS200 is at fault here, then I would definitely check the connections between the Debug Probe and the board - especially the cable and the small pin adapter board.

The error message is reported in the reference below. (just search for the error code)

Thank you,
