    Actually, now I have had a chance to connect a CRO to it, I am getting nothing via GPIO at all. Seems my .ld and .s is wrong for the toolchain, any hints on how to use ST Lib 3.3 with codesourcery?

    Just to confirm my assumption... the code works with other usarts?

    i should be volatile, or compiler can optimise out the delay loop.

    Found the problem, was iterating an array with sizeof, not the number of elements... duh! *face palm*
