Firmware Update

That's what I have when I connect the Wipy !

You are missing a jumper on TX, is it in the bag it comes in.

[Meide]

I have no jumper in TX and also in CHG, do you think the error can come from that ? What those jumpers are for ?

[Frida]

TX and RX are for communication via USB.

i do not see details on your picture - is the wire connected with second pin on the left and 4 pin on the right?
but maybe try first without the wire
and look if your Windows see it
and check if your usb port work on computer plugging some flash disc

Ok so, I added a jumper on TX and tried again. Same problem as before, I can't see the device on the device manager.
The wire is well connected between G23 and GND if it was your question.
Put the wire or not don't change anything, my computer doesn't see the WiPy in both cases.
And my usb port work with an USB key without problem ..
Any other idea ?

I think this is a good question, that's why I've created new topic https://forum.pycom.io/topic/310/expansion-board-2-0-feature-selection-jumpers

I've just noticed that @cappy2112 created such topic https://forum.pycom.io/topic/143/documentation-for-expansion-board-2-0-jumper-settings over three weeks ago, but without any respond.

@Meide
it is not visible or it show as "unknow device" ?
and what port have you on computer USB2.0, USB3.0 or old USB1.1?
Try with another port if you have - especially on back side if ypur ports are also on the front

[Meide]

It's not visible at all.
I have usb 2.0.
I am working on a laptop and I tried in all the 3 usb ports I have, same result for all of them

[Frida]

Have you tried another USB cable?

[Meide]

I tried to change the cable and ..... IT WORKS !!
My computer finally recognized the device and I could make the Update.
Thank you for all your help :D :D

And for those that interest, the connection works also without the TX Jumper
