Other Parts Discussed in Thread: CC-DEBUGGER

Hi,

I am using  Minimum connection for debugging cc2540EMK as shown in CC Debugger User’s Guide SWRU197E

. ie DD, DC, Reset, Vdd, Gnd and Vsense

I was using this setup for about last 1 month. But now onward it is not able to find the target.

The LED (green - red indication ) indication works fine. But IAR is not able to find the target

What could be the problem?....Please help

Regards

Gautam

    Hello Gautam,

    Are you able to program the device using SmartFT Programmer?  That will narrow your problems down a bit.

    Is the device still running the code that is in it?  That will determine if the device is faulty.

    If the device and CC Debugger work, then you have a problem with the IAR configuration.

    Thanks,

    Also, make sure that the CC Debugger firmware is up to date.

    Additionally, measure the current being consumed by the board when in RESET mode. It should be close to 1.65mA.

    Another quick test is to try running the board through SmartRF Studio. If it runs fine, it is an indicator that you have issues on the IAR side.

    Hi Greenja and Chatto

    I am not able to detect CC-debugger on any of the ports of my PC ( Win XP). Tried on other PC as well. However (green/ red) LED works fine on finding the target. 

    Also, I am not able to find the target on Smart Flash Programmer ( i connect the device via CC- debugger ).

    But BLE device seems to be running when powered up by a DC power supply, as it consumes the same current as it did before.

    I am  not able to detect the device on SmartRF studio also.

    @Chatto i will measure the current consumption on RESET and come back here

    Regards

    Gautam

    Look inside you Device Manager and see if the Cebral Device is there.  Try reinstalling the USB driver for the CC Debugger.

    Hi,

    There is no  Cebal device seen in the device manager. Can I uninstall the drivers from anywhere else?

    I tried re-installing drivers but for no change.

    The debugger seems to be totally un-responsive except LED indicaion.

    It seems that it can only power the target board and sense the voltage (at Vsense). Other then this its un-responsive.

    Regards

    Replace the USB cable with another one.  If that doesn't fix the problem, the open up the CCDebugger and have a look.  Perhaps there is a cold solder joint, or maybe if it dropped, it caused the an open circuit on the D+/D- lines.
