Papilio pro custom board UART problem

[Kaitou Kid 0]

I'v made a custom papilio pro board based on schematic and eagle pcb file that published, the board has 16mb flash spi instead of 64, I loaded the quick start bit file to the board and everything just go fine.both to SPI or FPGA.

the problem is when I tried to open the port of the FT2232 chip with putty as a serial monitor program, nothing show up,

I pressed buttons on keyboard and just some character show, and the rest are garbage( if I flashed to FPGA),

and putty go freeze if the bit file loaded to SPI (blank screen)

I use 32mhz OSC, voltage regulator just fine as I checked,

What more I need to check to solve this problem?

thanks all

sorry for my bad English
