CCS/CC2640R2F: CCS/CC2640R2F:

Part Number: CC2640R2F

Tool/software: Code Composer Studio

Hello,

I have the SaBLE-x-R2 development board and the XDS110 debugger. I connected the debugger via USB to my PC, and used the DEBUG connector of the XDS110 to connect it with my JTAG 10pin connector on the SaBLE-x-R2 development board. I then used the CC2640R2F.ccxml configuration to configure my XDS110. I selected the CC2640R2F Board and then did a Test Conections with the following output:

----------------------------------------------------------------------------------------------------------------------------

An error occurred while hard opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

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

The value is '-267' (0xfffffef5).
The title is 'SC_ERR_XDS110_TARGET_SUPPLY'.

The explanation is:
The controller could not detect valid target supply. Check target
JTAG connection and/or connection setting specifying voltage level.

[End: Texas Instruments XDS110 USB Debug Probe]

I should also mention that my SaBLE-x-R2 dev. board is not displaying any LED lights when connected via the JTAG connector, so i probably should add a power supply. Can I use the TGTSUPPLYOUT pin of the AUX. FUNCTIONS connector for that purpose, or should I use a rather simple USB power source?
