I have a Saxo board and I am trying to use the PA0/INT0 as a GPIO output (PA0) to the FPGA. This FX2 pin seems to connected to several configuration pins on the FPGA. Anytime I set the FX2 OEA = 0x01 then FPGA device loses its configuration or at least goes tristate. I saw this pin in the pinout file so I assume you can use it.

What am I doing wrong?

By the way, I am using PA1/INT1 as a GPIO without a problem, this only happens with PA0.

Any help would be appreciated.
