We are excited to share what we learned with our readers. Building the Linux Kernel was very easy, but creating a bootloader to boot Linux off of the on board SPI flash was a little more involved. Surprisingly (or not!) it turned out to be fairly easy to do. Recently we spent some time trying to figure out how to build Linux for Saturn.
Though a low cost FPGA board, Saturn Spartan 6 FPGA Module is perfectly capable of running Linux with Xilinx’s popular Microblaze 32 bit soft processor.
