The bad new I think from other places in the forum is there isn't a way to backup u-boot nand installs.
If your hda install is good, just reflash u-boot?
Its more simple by running "nanddump /dev/mtd1 /mnt/cf/mtd1_full_nand" will much safer.
then I will simply write it back.
I've huge pain following the steps in the forum. Following
this way, I am able to get the debian up running using 2.6.20 kernel and thats without uboot.
No matter what kernel I use, as long as I install uboot, my zaurus won't boot.... I wonder whats going on there.
Maybe If you can provide me exact steps to get debian installed on your c3100 will be nice.
Thanks,
