Firmware upgrade troubleshooting - checklist/procedure
-
I had issues trying to update my wipy 2.0 with a standard TTL serial programmer I use for Arduino. For some reason the low baud rate update in the software selects 38400 but the WiPy sold with old broken firmware has it set to 115200 which isn't even an option through the firmware update tool.
To change this you can edit C:\Program Files (x86)\Pycom\Pycom Firmware Update\Upgrader\bin\updater.py and set "SLOW_BAUD_RATE=115200". Then the firmware updater works just fine.

One should also check that all of the jumpers have tight connections. I couldn't get communication to work with my expansion board until I replaced the jumpers provided with new ones as the originals were quite loose.

I stress the need to reset LoPy boards after they have been connected to pc by data USB cable, and before you try to run the upgrade....

Unfortunately, this is currently not working for upgrading a module through either the Pysense or Pytrack boards using any GNU/Linux distribution.
