Hello all,

So I finally managed to boot from the CFI FLash. My mistakes were the following.

1) In hw_select I had to choose to boot from sdram, because I was choosing to boot from CFI Flash.

2) input instructions as follows. 

$ elf2flash --base=0x00000000 --end=0x007fffff --reset=0x0 --input=/home/pancho/nios2-linux/uClinux-dist/images/zImage --output=ext_flash.flash --boot=/opt/altera8.1/nios2eds/components/altera_nios2/boot_loader_cfi.srec
~/nios2-linux/uClinux-dist
$ nios2-flash-programmer --base=0x0 ext_flash.flash --go

Did the trick!

Thank you

Francisco
