Hi, The FPGA doesn't have much RAM so there is no point in using it to store ROM images. This is the reason why I have switched to Papilio Pro board from Papilio One. The Papilio Pro has 64k usable internal SRAM which is more than the previous board has, however still not enough. That is the reason why I had to do this trick to store ROM images in the same flash chip which the FPGA uses to store its config. In case of the Papilio Pro the FPGA configuration flash chip is tied to IO pins of the FPGA so after the core has started up the flash chip can be used by internal user logic. It has more than enough space (64Mbit).

I understand they are uploaded from some Flash chip that is on the development board, not from the FPGA itself? Because otherwise, why the FPGA itself could not act as a ROM chip? Regards, Michau.
