Failed firmware upgrade: LoPY on Mac OS X 10.11

[borjam]

I am trying to update the firmware, no success. I have verified that the serial port indeed works and the FTDI drivers are in place.

The LoPy is installed on an expansion board.

The PyCom upgrade says, Result:

This is the log of the upgrading process:
Connecting....

Failure!

And this is what I see on /var/log/system.log. Of course I have no clue wether it's normal or not, the "troubleshooting" section on the documentation seems to mean that absolutely no trouble can happen. Ever.

I can confirm firmware upgrade tool works fine on 10.11.6 which I am running on a MacBook Pro. I had one failure of the type reported on this thread (I am flashing 14 LoPys) but retired it and it worked fine second attempt.

I retried, no luck. And yes, it took several seconds. I will maybe try updating a couple of WiPy I got, although they are shelved for now. I need the LoPy units to actually play with LoRa.

On the bright side, I loved to see this on a SDR receiver:

@borjam, no clues. It should work on 10.11 (I'm running 10.11.6 now). I know is a silly question to ask, but, did you retry? Does it fail instantly or takes a few seconds before failing?

[borjam]

It just worked on 10.12, different machine. The 10.11 is a Mac Pro, the 10.12 is a Macbook Air.

I guess there is some requirements information missing. Any clues? I can try to find out if you give me some pointers.
