Once again, thank you to all that may offer help:
Moved my ext2 rootfs from old drive to new, larger drive and still able to boot up Debian using kwboot, but it takes several tries before I get the timing right. My goal is to have Debian boot without any intervention using the serial cable. I do not want to go back and hate messing with the stock uboot, prefer to use new uboot but confused on installing that. As I am learning, I keep trying different things to boot with the stock uboot, but so far the only thing that works is kwboot and the serial cable.
Can I install the new uboot from the devices installed Debian and if so can you point me in the right direction?
If not here is where I am stuck now:
I tried several methods including the boot stock using
"3. Booting with stock u-boot that supports sata (ide command), ext2load, and run commands"
but it results with bad partition can not read ext2 error
