PS Configuration with Commodity Flash

Thanks Frank,

I am planning on using the SPI flash similar to how it is set up in the configuration documentation for PS configuration. The microcontroller will be driving the clk and address lines of the the serial flash chip and the data out line will feed directly into the FPGA, so the microcontroller will not be able to do anything to the bit stream. Upon reading about the .RBF again, it looks like this file is simply a bit stream and not broken up into bytes. I will just have to be sure it is initially loaded into flash correctly, which I'm going to have to write code for anyway as the Altera flash programmer only works with their chips or CFI flash from what I understand. It's too bad we can't just use commodity SPI flash in place of Altera's EPCS chips (very pricey). I'm going to look a bit more into the HEX and TTF file formats as well as these may be easier to program into the flash initially using the microcontroller. Perhaps this is where your table idea could come in handy.
