What do you mean by "doesn't work"? That's very vague. > something wrong with FPGA. but the clock of FPGA and ADCs are all OK, and > FX2 to FPGA connections are also ok. it seems rbf cann't load to FPGA, why? > can you give me some guide? thank you again. How do you know that the rbf isn't loaded? Does $ usrper load_standard_bits give you some kind of error? If you're using a different model of Cyclone, the precompiled rbf won't work for you. You'll need to build one that's appropriate for your device. Take a look at the Cyclone datasheet and read up on how it's loaded. With a logic analyzer, you should be able to watch all the relevant signals between the FX2 and Cyclone. It's been a long time since I looked at that datasheet or code, but there's some combination of signals that indicates "start loading", "loading completed successfully" and "loading failed".
