LAUNCHXL-CC2650: FLASH XDS FIRMWARE

If you run xdsdfu.exe again, does it recognize LAUNCHXL-CC2650?

Have you tried mass erase with Flash Programmer 2?

No, it doesn't. Even the windows doesn't do nothing about inserting a new USB.
When i run xdsdfu -e it says no devices connected.

No. I can't do nothing because the board doesn't show up in Connected Devices.
Maybe there is any way I can force write the firmware on USB COM even without showing ? I know the COMs connected when it worked.

It sounds like the XDS debugger has died.

Do you have only one launchpad? If you have two you can try to use the debugger from one board to program the CC2650 on the other board.

Yes, only one.
There is no way I can repair it?

I suspect that you at least need to re-flash the Tiva which would require a special cable and the correct image.

Why did you use xdsdfu to flash the CC2650? This is a xds tool, to flash the CC2650 try Flash Programmer 2 or Uniflash.

Well, let me explain again: I used xdsdfu to update the firmware for xds, it says OK and I guess the USB port moved a bit and the the update failed, or it had a bug and didn't write on correct address. By that time, the Launchpad doesn't get recognized by the PC anymore.

And yes, I used FlashProgrammer or or Uniflash to program the cc2650. That worked very well before.

I did some research and I have to reflash the xds through P8 pins on the back of Launchpad.

Now my questions are : 1) The firmware provided in xdsdfu directory from CCS is full firmware or just the update?

2) From which address starts the firmware in xds? I didn't find this in any docs.

Thank you very much again for your time!

Hi,

I have a similar problem and I have a second launchpad. How would this procedure be like? Do I need any special cable for this purpose? I've searched the web for this but I cant find anything, maybe my search terms are not appropriate.
