Honored ContributoruClinux boot from epcs ?
If someone like me wants to run uCLinux on a Nios2 but the fpga must not be a bga type then the biggest fpga available is EP2C20 with QFP 240 pins. That one can be handsoldered http://forum.niosforu...

you can use u-boot in such a design ... as it supports cf as well as epcs. if your
epcs is large enough, you could fit the entire kernel ... u-boot can load, decompress,
and boot a gzip/bzip kernel image (same goes for cf of course).
currently, i load u-boot from epcs and then boot a gzipped kernel image (~520 kb)
either from parallel flash, a tftp server, or an nfs server. same goes for the cramfs
filesystem (which gets stuffed into sdram as well).
