Devkit not working

[Henryw]

I found someone else with the same error I had in this forum:

Dev Kit programming - dev board no longer flashes green when connected

After completing user guide #3 I received the following on the spotter console: Node c26a1077e2872d6a update status: 1, 0 Update finished: c26a1077e2872d6a success: 1 err:0 On the Dev Kit console it reads: serial.serialutil.SerialException: read failed: [Errno 6] Device not configured Following this, the dev kit no longer flashes green when connected to power. It does not accept power from the wall charger and will only get power when connected to the spotter. When I enter the Dev Kit cons…

I saw the fix was to upload new firmware so that is what I did. However, when I am trying to upload the new firmware to the devkit I am not able to use bm topo to get the ID to push the firmware. When I use bm topo on the spotter terminal I get told it is not a valid command. When I use it on the devkit I get “bm topoTimed out waiting for ready flag!” I assume this means I am not able to get the ID for the node I need. This means I am not able to push the new firmware update that fixes the problem.

I believe bm topo only works from the mote presently.

What method for firmware upload are you using and how far did you make it into that process (link me to a step in the guide where you got to last).

I managed to get it working, when I used the bm topo in the terminal for the devkit terminal it appeared at some point and I was able to use that to install the new firmware. The devkit now works

I used the bottom of this guide once I found the ID

Great! DFU-Util is a nice little tool and is well documented here if you get stuck anytime using that method: Ubuntu Manpage: dfu-util - Device firmware update (DFU) USB programmer
