Still struggling to get the firmware upgrade to work on linux.
Note, I'm not using an expansion card but a Serial USB cable which powers the device up and allows me to connect to the wifi
I'm also able to connect to the serial port with minicom and I get the following python version:
>>> print(sys.version)
3.4.0
>>>
When I try and update the firmware I get the following error.
Namespace(file=None, port='/dev/ttyUSB0', speed=115200, tar='/tmp/tmp.zR12S6HK0s/update.tar.gz')
Connecting...
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 115200
Changed.
Exception: empty file, on line 131
This what I am doing exactly:
As root Downloaded and extracted pycom_update_1.0.0.b3.tar.gz
cd into pyupgrade
run ./update
select WiPy 2.0
Disconnect device from USB
Put G23 into GND
Plug in USB cable
Press and hold the the reset button for about 3 seconds
Press enter on the update
Type in the serial path :-> /dev/ttyUSB0
Deselect high speed
Then it fails with the "Exception: empty file on line 131.
Just to be sure my EMS32 connectivity is good, whilst connected via minicom, if I plug in G23 to GND hit reset, I see the device is waiting for a download

rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download
Perhaps someone can point me to the firmware file and a command line script I can use to test the install. I really would like to complete the upgrade and get on with using the device :)
