Honored ContributorOK, thanks everyone!
My whole board runs at 3.3V, which is supplied by a switcher from Linear (the LTC3031). I checked with the Linear engineer, and he confirmed that it would not harm the switcher to backfeed it (although he had some practical reservations). Having said that, I think that we may actually just build a little bed-of-nails programmer and supply the normal voltage to the board for programming. That seems like it is the best and safest way. The way I designed my board, supplying 3.3V via an intercept in the Blaster cable probably *would* work, but I think that it may not be the best way. However, it seems like this would be a common issue, and it would be cool if Altera could come up with an "official" way to do it! :) Robert
