Problem with CC Debugger on CC2540 ( USB dongle hardware )

Other Parts Discussed in Thread: CC2540

Hi ,

I am having problem with setting breakpoint with CC Debugger. I am working on the software BLE stack 1.2 which runs on the CC2540 mini keyfob development kit. When I try to setup a breakpoint in the software for the USB dongle, the software can’t run, with a message “Unable to execute: driver error” pop up.

The device can then run without the CC Debugger if I cycle the power, which means that it is actually programmed and the hardware connection is fine. It just fails to run in debug mode with a breakpoint.

 I have to remove the breakpoint in order to have the software run in debug mode. But even if it runs, the same error will appear if I pause the debugging by “break” button on IAR and then run the program again (without resetting the device )

Anyone has similar problem and can give me some advice?

Thanks.
