Discovery 3000 PROM programing

Hi,

I`m currently developing new imaging device using a DLP Discovery 3000 board.  When trying to upload software into the prom (xcf08p), it stops after only 4% without any error message.  So I have to reload the software manually on the FPGA each time I turn on the board.  Does someone have any idea of what could be the cause of this problem?

Thanks,
