u-boot + stratix EP1S40 + issue

hi scott,

It didn't work properly......here are the steps after I download the u-boot on EP1S40 board using "nios2-download" under XP.

after I reboot & start my debian linux...with "kermit -c" ....I followed ur instuction.....& here what I got.

DK1S40 > tftpboot 1100000 uImage

Using MAC Address 00:07:FFFFFFED:0C:04:FFFFFFBD

TFTP from server 10.0.0.1; our IP address is 10.0.0.51

I am not sure if it's something to do with mkimage utility ........because....if I download the linux kernel alone....using "nios2-download -g vmlinux"....it display the booting process on hyperterminal.....Any idea.....what's wrong????

BTW, here is the command that I used to create uImage.

./tools/mkimage -A nios2 -O linux -T kernel -C gzip -a 0x01000000 -e 0x01000000 -n "Linux Kernel Image" -d linux.bin.gz uImage

Thanks,
