Hi team,

When I use CCS Target Configuration file to test the connection of XDS110 debugger of LAUNCHXL-F280039C, it will show:

The jumpers for JTAG are all connected. And FTDI driver is also installed in my PC. How to solve this problem?

Hi Will,

Please make sure that the target configuration is set up to use cJTAG in 2-pin advanced mode.

Refer to Launchpad user's guide.

Is it okay that the JTAG communication method is different between F280039C and F280049C?

With F280049C, I was able to communicate with "JTAG (1149.1) SWD and cJTAG are disables".

Astro,

Yes, it is okay to have different JTAG configuration between different devices. Actually, F280049C Launchpad, you will need to use cJTAG 2-pin advance mode like F280039C. Only on F280049C controlCARD, we use XDS100v2.

Thanks & Regards,

Santosh
