Hello,
How do you determine the offset of the gpioxx.
#!/bin/bash
#This appears to work with fpga.bin loaded
echo "++ Exporting switches "
for i in 0 1 2 3 4 5 6 7;
do
sw=$(($i+65));
echo $sw > /sys/class/gpio/export;
done;
#!/bin/sh
value=0;
for i in 0 1 2 3 4 5 6 7;
do
sw=$((72-$i));
sw_tmp=`cat /sys/class/gpio/gpio$sw/value`;
value=$(($value*2));
value=$(($value+$sw_tmp));
done;
printf "0x%x %d
" $value $value;
This work with the system.ucf.

I can not get the LED to work.
Thanks
