CC2650: doubts on designing debugging/programming CC2650 circuit

Part Number: CC2650

Hello

I followed information regarding the CC2650 debugger but wasn't able to find out which debugger fits my requirements and how are pin connections.

in the uTag schematic I see only two wires used for debugging while in SensorTag it's 5 (including TDI and TDO). May you please let me know what is the difference and explain me all the things I need to debug my MCU.

In the discussion, somewhere it is said that XDS110 doesn't support cJtag, another board said it is possible.

Also for serial connections, can I connect my I2C and SPI and maybe other types to any pins or there are certain pins? (sorry maybe my question is elementary, but I've seen things which mad me confused).

Thank you

Amir

Hello Amir,

Which guide did you follow? cJTAG is supported in the most recent CCS emulation package for XDS110.
Also, I suggest reviewing the Complete Tools Overview wiki article on the TI BLE Wiki.

Best wishes

cJtag uses 2 lines TMS and TCL and Jtag uses 4 lines which TDI and TDO are extra. CCS supports both cJtag and Jtag connection. Since uTag targets for compact size, it uses cJtag connection to save space. For CC26XX, you can configure any pin to I2C and SPI.

Hi
Thanks for the reply. I followed this discussion:

It would be great if you remove older discussions that are not valid anymore, as it takes to much time to follow whole the conversations.

Thank you
Amir
