Despite playing with my miniSpartan3 board for quite a while, I’d never attempted to write my FPGA designs to the SPI flash on the board. This means that the FPGA board didn’t do anything until I deployed my design onto it manually - quite useless if you were using the board for a real project, and on power-on you needed it to go to work immediately. Turns out though, it is fairly simple to do, as long as you have the larger XC3S200A variant with an Atmel AT45DB041D flash chip - that’s ...
