CC Debugger connection to CC2541

Other Parts Discussed in Thread: CC2541, CC2540

I'm working on my first CC2541 project and found myself at a loss on which pins should be hooked to the CC Debugger.

This is the pinout listed on the large to small pin adapter for the CC Debugger:

GND VDD
DC DD
CSN SCLK
RESET MOSI
VDD MISO

Which CC2541 pins should connect to the adapter pins highlighted in orange?

    Hi Danny,

    The answer is no!

    In order to be able to program cc254x devices you need to connect your device with the following signals:

    • GND - common ground (connector-pin #1), MUST
    • VDD - voltage level feedback to CC debugger (connector-pin #2), MUST
    • DC - Debug Clock (connector-pin #3), MUST
    • DD - Debug Data (connector-pin #4), MUST
    • RESET - Reset (conector-pin #7), MUST
    • VDD - Power (connector-pin #9), is optional, used in case if you want to power
      your target from CC debugger.

    To add to what Igor said.

    Check  Pg3 of the schematic in the CC2540 kefob ref design for additional conntection for CSN, SCLK, MOSI and MISO

    However, remember, you only require DD, DC, RESET, VDD and GND to debug or program a CC254x device
