My supply voltage is 3.3V, but when I was getting an occasional 0x15, I had some fairly long lines that extend out to the pads that will hold the other FPGAs attached with no series resistors or caps.

I had a bit of other work to do, but right now I'm going to start connecting those other lines through resistors one by one to see if it works, and if it doesn't, try to isolate the problem.

Will update with the results.

Thanks for the info!
