[Solved] LoPy firmware update issues

[Burgeh]

Greetings,

I just have received a LoPy SOIC and a Pytrack expansion board, and I am new to the system. However, I have been following the Pycom.io tutorial succesfully. I only have one issue, I cannot seem to upgrade the firmware on my LoPy using the Pytrack expansion board.

The Pytrack has the correct driver of libusbK(V3.0.7.0), I confirmed through use of the Zadig software.
The current LoPy OS info is release =1.0.0.b1, version =v1.8.6-237-g9d21f17
My PC OS is windows 10, and I am using the windows Download from here: https://docs.pycom.io/chapter/gettingstarted/installation/firmwaretool.html

COM port appears correct COM3 in my case, I connect to it through ATOM, and it is set on the firmware software. I've tried unchecking the high-speed box, making sure atom is not up, below will be the settings I used.
Thanks in advance!

@burgeh You can start by manually downloading the latest LoPy firmware and flashing it with the latest firmware updater (select "Flash from local file").

To get your board updated for online flashing please run the following command on your board:

import machine,binascii                                                     
binascii.hexlify(machine.unique_id())

and send the output to support@pycom.io asking for your board to be changed from LoPy4 to LoPy.

@burgeh
you must send info to pycom support, they store device info for updater tool in internal database

Thanks you helped me refocus my efforts towards the DFU files, not just the drivers. I needed to use the cmd console to update the dfu files...That worked!

-Additionally, it appears I programmed one of my LoPy 1 devices as a LoPy 4, and I cannot re-select that board type when I download the firmware, any suggestions? Or is there little difference?

@burgeh
did you updated firmware of your Pytrack first?

only after above step you can do update of your lopy throught pytrack
