Other Parts Discussed in Thread: CC-DEBUGGER

Dear all

I am using cc2533f64 Microcontroller with IAR V7.60.1 compiler. when i tried to load the hex file using CC-Debugger is give the following error. "Fatal Error: Failed to identify device,check connections and/or reset hardware". The CC_debugger always show's red indication for both IAR and Flash RF studio. I suspect problem may be in hardware. here i am attaching the circuit diagram.please tell me any corrections required.

I would suggest changing the resistor between the reset pin on the debug connector and the reset pin on the radio to a zero ohm resistor. The debugger needs to toggle this line to setup the debug mode of the radio and the resistor and capacitor will interfere with this operation.

Try to reset the USB connexion with the button "USB RESET" on the evaluation board. It's working for me when there is this error.
