I have a couple of that neat boards with XO2-7000 and not much else.
I managed to burn the FPGA on one of them and since Farnell didn't have the exact 7000HE model that was on the board, I used 7000HC and bridged VCC so that chips gets 3.3V for core power that it wants.
But now I can't program it through FTDI. I've noticed several variations of the board. Some had XO2-1200 while mine have XO2-7000HE.
Shoould this with pin-compatible chip just work or do I have to have different EEPROM content for FTDI ?
BTW, trivial "blinkenled" example on _this_ board fails with:
Device#1 LCMXO2-7000HC: Failed to verify the ID
(Expected: 0x012BD043 Read: 0xFFFFFFFE).
ERROR - Check configuration setup: Unsuccessful.
ERROR: pgr_program failed.
ERROR - Programming failed.
If it doesn't work through FTDI, I'll use ISP cable on it, but it's nuisance...
