LAUNCHXL-CC26X2R1: cc26x2r1

Dattatray Hinge

I am using LAUNCHXL-CC26X2R1 for initial development, but I am wondering how to usecJTAG in the MCU without XDS100 debuger or with thrid party debugger. Pls advice jumper setting of lunchpad to isolate XDS100 debugger.

Secondly how to switch between JTAG and cJTAG? What is default mode?

Hi Dattatray,

Have you seen the "Advanced use of the LaunchPad hardware" section of the LP User Guide? http://dev.ti.com/tirex/explore/node?node=AEkWQJzOeou7V3Syra6w9w__FUz-xrs__LATEST

You can use the .ccxml target configuration file -> Advanced Setup -> Target Configuration of the CCS project to change JTAG modes (cJTAG is default) http://software-dl.ti.com/ccs/esd/documents/ccs_custom_target_config.html

As I know, CC26x2R1 doesn’t embed XDS debugger. You have to use XDS110 on LaunchPad or external debugger for development.

Yes, XDS110 is on Lunchpad

Can get the protocol details of cJTAG, basically I am reversing protocol used in cJTAG.

If possible please share cJTAG protocol details

You can refer to screenshots in https://sunmaysky.blogspot.com/2016/06/?m=1 to switch Jtag/cJtag in CCS.
