FiPy on Expansionboard 2.1A stopped functioning
I have just started using my FiPy on an older expandion board (only one available to purchase in Australia). It worked fine when I first powered it up. But on second use; I no longer get any Comm port enumerate in device manager when I connect the board.
Tried all combinations of power supply options (just powering with USB, also powering with lithium battery, external regulated 5V to the Vin) - multiple laptops, multiple serial cables - no dice.
The device does appear to power up and start blinking its blue light - which suggests to me it running its default code.
Any advice / known issues I should be aware of with this hardware? Recommended tests? This device is not too easy to debug given the lack of schematics - am I missing a repo or something?
Thanks in advance
Well - this is embarrassing..
I first tested this at home, I had 3 micro USB cables - the first one I used worked. I travelled to site; bringing 2 micro USB cables with me - and I'm sure you already know where this is going..
Those cable appear to power up the FiPy only - and not allow the comm's to function. I borrowed a 3rd cable yesterday - and it worked immediately..
Thanks for your support - cutting all my "power only" micro-USB's in half..

@Antman Are all jumpers closed?
@Antman The expansion board should show up as a USB device even without the FiPy installed.
- Did you change any of the switches?
- Have you tried to upgrade the expansion board firmware (though I'm wondering if that applies to the 2.1 version or only 3+, don't remember when they switched to a PIC for the serial/USB connection)
- What OS are you using on your computer?
Also you mention serial cables, you mean USB cables, right?
