Error: CONF_DONE failed to go high in device 1.

Before anyone comments on this, I have searched the forum and read everything I have found on the internet with people getting this error message. :) I'll try to post as much relevant information ...

Hi,

according to my datasheet (which might be not the most recent) the combination

MSEL0(H13)=2,5V, MSEL1(H12)=GND, MSEL2(G12)=GND

is defined as Active Serial, Standard. (my configuration is MSEL0(H13)=2,5V, MSEL1(H12)=GND, MSEL2(G12)=2,5V, i.e. Active Serial fast...). As this is just the frequency of DCLK I would assume this not being anything to worry (except you need "fast mode")...

Maybe you should use a DMM and measure the resistance of CONF_Done to GND (w/o board powered) - maybe there is a "hard short"?
