XDS100v3 Debugger setup for CC2640

If you use Flash Programmer 2, can it read your CC2640(5x5) with XDS100V3?

Hi YK Chen,

I can see the XDS100v3 listed but not the CC2640 as shown above.  Can you or your TI tooling colleagues provide a schematic/hookup diagram of how I can connect correctly the JTAG pins to a bare CC2640 board so that I can JTAG connect to it?  My XDS100v3 debugger has the TI_JTAG_20PIN connector.  So how should I connect up the pins like T_DIS, T_EMU0-T_EMU4, T_DIS, T_RTCK, T_RST_N, T_SRST_N, TVD  which I am unsure how to correctly.  For T_TMS, T_TDI, T_TDO and T_TCK I assume then connect directly to the corresponding JTAG pins on the CC2640.  Please show all the necessary, pullup/downs, termination, etc which are required for all the JTAG signals above in order for the XDS100v3 to be able to communicate successfully with the CC2640. 

On the software settings side, can you please provide all necessary configuration settings(ccxml) that I need to setup in CCS6 for this to work successfully too? 

Also, can you please advise if the XDS100v3 can only connect via CJTAG(1149.7) and not the full JTAG(1149.1) , or are both supported for connecting to the CC2640 family? 

Thanks! 

     

You can refer to the discussions in e2e.ti.com/.../421057. The signals needed to debug the CC2650 are TCK, TMS and SRST_N (RESET_N). In addition, the XDS100v3 needs the target voltage detect (TVD) signal connected to the target VDD. By the way, I am not TI employee. Just try to help anyone here.

Hi,

I have been trying to get my XDS100v3 Debugger to work with my CC2640 custom board.  However, no success in connecting.  I have used settings below and  have been getting the following error message when running "Test Connection" in CC6 to test the JTAG connection. 

 

[Start: Texas Instruments XDS100v3 USB Debug Probe_0]

Execute the command:

This error is generated by TI's USCIF driver or utilities.

The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.

The explanation is:
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

Also, I have probe the TMS and TCK line on the JTAG connection, an got the following oscilloscope capture

The yellow trace is TMS, the blue trace is TCK .  Looking at the signalling pattern, the TMS doesn't look correct.  Can someone please advise what maybe wrong and how can I rectify the problem so I can JTAG connect successfully to my CC2640 board?  Please help. 

Hi Mitw,

I think what you are looking for is something like this:
www.ti.com/.../swru321a.pdf

The link above provides the SmartRF06 evaluation board schematic. Note that the SRF06 board has the XDS100v3 attached to it. You can see how the JTAG pins connect to the CC2640 EVM from here. There are also a lot of descriptions and tables regarding jtag and debugging.

In order to complete the loop, you can find our EVM schematics online as well, here is a link the the 7ID EM.
