Upgrading uboot on Globalscale Sheevaplug

#So I downloaded ubuntu and booted the macbook from the cd. I reformatted the usb stick, with 3 partitions, SDA1, SDA2 & SDA3. (1.0 Gig, 1.5Gig and 1.5 Gig, respectively)All are FAT 16 and SDA1 is bootable.

Bad Magic Number

#I have successfully upgraded uboot by using TFTP Server. However, run bootcmd still returns 'bad partition 1' and
'bad magic number'. I'm thinking that perhaps I have formatted and partitioned the stick wrong. There are many options within Ubuntu's disk utility for formatting options. I selected Master Boot Record and FAT 16. Perhaps something else would work better?

OK, since yo upgrade u-boot, we can do some debugging. lets start by building some common understanding. What is your u-boot version? where do you think you root file system is? i.e usb device? NAND? or SD card? what is your kernel version? do you know if your kernel need initrd/initramfs?
