Cyclone3: Flash programmig via JTAG

Hi, I’m a student and I started my first FPGA project a few weeks ago. I want to create a “Bootloader” which programs my external flash memory via JTAG. At that point I program my flash memory...

I haven't really used CFI flash chips... But the programmer seems to be looking at the correct place.

Did you create an .sdc file with timing constraints for TimeQuest? You should at least declare your clock inputs so that it can get the internal timing right. Then you'll probably need to constrain the CFI interface too. (and use the derive_clock_uncertainty to get rid of the critical warnings, but don't think those are related to your problem)
