come to think of it...now that you pointed it out...my sheeve plugs do that and i didnt realize that is what was happening here ....ill use the sheeve plug as a reference since im familiar with that.

Thanks for pointing that out :)....it isnt the fact that the file is on a ext2/3/4 partition..its raw data on the storage system and not a file on a partition..which explains why any file sytem mods i made did not affect the boot of the kernel....

I usually create a 100MB ext2 filesystem...put the kernel there...than boot to a ext4 filesystem as root. ill redo that and make the u-boot changes needed....now this makes entirely more sense to me.

Your default boot commant is not very friendly, loading the kernel from
raw blocks on the mmc controller (sd card etc).

I would recommend you make a new bootcmd_ext2 which uses ext2load to
load the kernel. Much easier to change kernel that way. Then change
bootcmd to refer to that one when verified working.
