Firmware upgrade troubleshooting - checklist/procedure

I'd add making sure you have nothing connected to the board other than the serial, power and GND-G23 connection.

Point 4 added. :)

Very good list, certainly useful for beginners like me!

I don't know if it is relevant but when i wanted to update/connect through USB I had to install the USB driver manually. Mine called FTDI driver where VCP or D2XX are types of drivers. With one of the two it said it was installed but still i coudn't update/connect.

But you were trying to update using Expansion Board USB or xPy board + USB2TTL serial converter?

For Lopy "Connecting ......... Failure !"
see post https://forum.pycom.io/post/4518

between 3 and 4 : use the RESET buttom on the Lopy

@dClaus One more time - thanx! It's already updated. :)

OK. In a free time (I hope this weekend) I'll grab a fresh install Windows machine and try to investigate FTDI driver issue.

On linux remember to update/place a file in: /etc/udev/rules.d

I have these in my: 45-espruino.rules, then you don't have to use sudo su

# To go in /etc/udev/rules.d/
# Makes Espruino's serial port accessible to non-SU users, and stops the Modem Manager trying to enumerate it

OK, I took my notebook with Windows 10 Pro x64 with internet access and plug LoPy on Expansion Board to it for the very first time.
Here is Device Manager just after connection:

After about 30 seconds Windows Auto Update mechanism has done all the job:

As you can see it is pretty straightforward - at least on Windows 10.
What OS are you using?

@rskoniec

Aah thanks for the update. Really fast!!

Now that u mention that windows installs the update automatic, I remember that I disabled windows update on my windows 10... that explans a lot! How stupid...

Sorry for wasting your time, but thanks for the fast answer and for trying it out.

@rskoniec thank you
I did my updated

[rskoniec]

@mmarkvoort @maamar You welcome. :o)

[yunying]

Thank a lot.
Reply just for feedback.

Make sure your jumper at "TX"

[colinza]

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.
