Reconfiguration from PROM after power-up

Spartan-3 USB 2.0 Modules
1

Hi,

I have programmed PROM with my design. Now after the power-up I expected FPGA to be reconfigured but it doesn’t. When I press S1 (J2 closed) FPGA got reconfigured correctly (so PROM is programmed correctly and all connections are ok). Are there some settings I should set to FPGA be reconfigured after power cycle?

Thanks,
Dominik

The recommended settings are listed in the XEM3010 User’s Manual.

Hi,
All my settings are as in the manual. It looks like it doesn’t get reconfigured after power-up, but it does when I toggle PROG_B (using S1). Any clues?

Thanks,
Dominik
