21 years agoHi MRks,
If your're using a cyclone device with enough memory in the epcs to hold the u-boot monitor, you can load a ramdisk & kernel via tftp (if you have an ethernet device) or serial port with 'loadb' (kermit) or 'loads' (srecord). u-boot is somewhere in 64K - 132K range depending on the features that you enable. Otherwise, you might want to take a look at how the old germs monitor worked ... and do something similar. As I recall, germs was small enough to fit into a 4k on-chip rom. Regards, --Scott
