LoPy Firmware updates fail on Win10

Oh OK sorry, I was going by the second screen where he tried it..

Can you try another microUSB cable? I know you said it worked before but maybe it was another one. There are many "power only" cables out there which could explain these symptoms.

I dont think Pycom actually send USB cables, at least I never got one.

Also try connecting to a different port on your computer. Until it's detected as a device it won't really work.

Neither do I.

For comparison, I checked what happens when I plug and unplug an arduino. Then, "Arduino Uno (COM6)" pops up in device manager when I plug it in, and it immediately disappears when I unplug it.

I assume that for Arduino test you've used different USB cable as UNO have USB B type connector.

@rskoniec and @jmarcelino,

Just now I tried updating with a different USB cable (of my phone, of which I was sure the data channels were connected), and a couple of things happened:

• A new device popped up in device manager
• The firmware update worked perfectly fine
• I thanked you guys silently for preventing me from wasting any more time.

So, solved! It amazes me how such a tiny mistake can cost so much time (in total, I spend a whole day on this).

Thanks!

@Jakko We're happy for your success. It's pretty regular that small mistakes sometimes make huge problems. ;o)

I've created a new topic https://forum.pycom.io/topic/763/firmware-upgrade-troubleshooting-checklist
I think it will be helpful for the others having similar issues.
I don't know if place in forum hierarchy is right - if not I hope Forum Admins will do the job. ;o)

I have also the "Connecting ......... Failure !" problem with windows10 for the update of Lopy 1.4 to 1.6 !

The solution is :

• set the connection between G23 and GND,
• connect the LoPy expansion board to the computer with a USB cable
• !!! use the RESET buttom on the Lopy !!!
• use the firmware updater (1.1.1.b1)

It works for me on my 2 Lopy !

"use the RESET buttom" is not necessary for the WiPy2
