15 years agoSorry, I made a mistake in last post.
The Bank1-2 is powered by 3.3V instead of 2.5V. So the configuration "0010" is suitable. It turns out to be a hardware issue. I use a LED between conf_done and 2.5V power to indicate the process of configuration. But this LED will drag the voltage down, and make the FPGA can not boot correctly. Replace the LED with a 10K resistor could solve this problem. In terms of the "conf_done" pin, only pull up resistor is needed. Any other capacitor and LED are not soldered. Thanks Derek
