FPGA Central

Hello,

to talk to the SPI flash on the s3e starter kit board, I have some code that
invokes the BSCAN_SPARTAN3 primitive and additional sets and locates
DAC_CS = AMP_CS = SF_CE0 = FPGA_INIT_B = 1 and AD_CONV =0;

NET "DAC_CS" LOC = "N8" ;
NET "AMP_CS" LOC = "N7"
NET "AD_CONV" LOC = "P11" ;
NET "SF_CE0" LOC = "D16" ;
NET "FPGA_INIT_B" LOC = "T3";

That way I can talk to the SPI device. The first access however often fails.

After an SPI access through that core, a press on the PROG button of the
board triggers reconfiguration, and the DONE leds lights up after a short
while, but the inital program scrolling the LCD doesn't start. It only
starts after repowering the whole board.

Any idea on what contention I hit and how I can solve?

Thanks
