@Simon. Getting there.
as cmd line params -m thumb targets 16bit instructions.
Now compiling without error.
I thought someone said this was Risc :-)
Makes some CISC processors look quite trivial!

Re: Buying cables in preparation....

Thanks Abishur. Getting there.
The micro vs mini is a cable issue, so the 'Apple', at 1A is fine.
The HDMI to DVI cable I linked to is spec'd at 1.3a so should be fine.

Got there in the end.
