A pullup can make D1 ON when in manufacturing mode[default] which is actually for diagnosis to know if power supply circuits work well in factory while/before no any f/w ported in. * if we want to experiment with a DVI input, the clock signal (currently on > W14/Y14) should be connected to pins with a dedicated route to the global > clock buffers (BUFG).

Swapped. :-) applied to: http://downloads.qi-hardware.com/hardware/milkymist_one/sch/20120323/Milkymist%20One%20R4%20-%2020120323.pdf Thanks, - adam
