LAUNCHXL-CC2650: CC2650 LaunchPad USB connection issues

Hello Sang Min Bae,

Could you perhaps try UniFlash? I did a small test with my own Rev 1.3 CC2650 launchpad, and was able to open a session with UniFlash and read the memory. 

Thanks,

Hi Alex F.

I tried to connect using uniflash, but I couldn't connect as shown in the picture below.

Are there any other solutions?

Thanks,

Sangmin.

Hello Sangmin,

I wanted to ask if this board was programmed before, and when programed before it may have been set debug locked? One issue that occasionally happens is if the device was it disconnected while flashing it may cause a similar issue.

Thanks,
Alex F

Hi Alex F.

I have never set it to debug lock.

I think there were a few times when the device was disconnected while flashing.

Please check if there are other solutions.

Thanks,

Sangmin

Hello Sang Min Bae,

Are all the jumpers placed correctly? Looking back at your first image GND and 3.3 V seem to be disconnected (among 3 others); could you re-connect all these as these are required for debugging/flashing. 

Thanks,
Alex F

Hi Alex F.

As shown in the capture photo below, USB connection is not possible even if power is supplied after connecting the jumper as you said.

There seems to be no solution.

Thanks,

Sangmin
