Wipy 2 first firmware upgrade failed

[dg66]

Just got my 2 wipy2 some days ago. Tried to upgrade firmware to latest (0.9.3.b2) and .... failed ;-)

What i did (i'm under ubuntu 16.04)

• download and unpack the firmware upgrader
• connect pin 23 to GND (expansion board)
• connect expansion board to a usb2 port (usb3 are known to have issue with some devices and this is not related to wipy)
• use the firmware updater (not using the bash script but bin/updater.py).

Here are some data:

• dmesg (see that the usb ftdi is available)

• check that device is available in /dev

 ls -la /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 nov.  14 09:18 /dev/ttyUSB0

• Try to update the firmware and boom !

/usr/bin/python2.7 bin/updater.py --port=/dev/ttyUSB0 --file=firmware/wipy_0.9.3.b2.bin 
Namespace(file='firmware/wipy_0.9.3.b2.bin', port='/dev/ttyUSB0')

Exception: Failed to connect to ESP32: Timed out waiting for packet header, on line 75

Any hint to help me ?

Thx

Oh ! did not noticied there was a missing jumber on the expansion board (realy missing at unboxing the expansion board).

Thx a lot, everything is working fine for now

@dg66, we've seen this happen a few times in the back, and they are related to missing jumpers in the expansion board. Can you please check that all the jumpers in the corner are in position and come back to me?
