PyTrack CORE DUMP LOOP

[Glagnar]

I have an empty LoPy ( i.e. no code on it ) and it core dumps when inserted into my PyTrack v1.1. When connected to an old Expansion Board 2.1a it works fine.
I have tried upgrading and downgrading the PyTrack to versions:
pytrack_0.0.2.dfu
pytrack_0.0.3.dfu
pytrack_0.0.4.dfu
pytrack_0.0.6.dfu
pytrack_0.0.7.dfu
pytrack_0.0.8.dfu
...
none of them help.

@glagnar Hey,

Pretty sure I just responded to your rma a short while ago you can go ahead and ignore my request to confirm its running the latest firmware in that now I realise its linked to this thread :). Ill update the RMA shortly :)

@paul-thornton Thank you, I am very grateful. I have created an RMA as I seem to have narrowed it down to a defective board. My second PyTrack running 0.0.8 of the formware works perfectly.
I have also ordered 5 new PyTrack boards, so we can continue our development :)
