Digging up this old thread, I'm taking a first look at Luke-Jr's Icarus board. (Literally have had it < 15 minutes).
Preliminary checks show a pretty significant voltage drop (well below what the LX150 FPGAs want) on the power output to the chips.
First thoughts are just one of the small power components have failed, possibly due to heat or surge or a faulty power supply. Going to test some of these and go from there.
Definitely using a sufficient power source for testing, so, that's not the issue.
More when I figure it out.
