This should work:

setenv bootargs $(bootargs_console)
usb start
ext2load usb 1:1 0x00800000 /uImage.bak
ext2load usb 1:1 0x01100000 /uInitrd.bak
bootm 0x00800000 0x01100000

But before you do that, can you try:

setenv bootargs $(bootargs_console) earlyprintk=serial,ttyS0,115200
usb start
ext2load usb 1:1 0x00800000 /uImage
ext2load usb 1:1 0x01100000 /uInitrd
bootm 0x00800000 0x01100000

or maybe:

setenv bootargs $(bootargs_console) earlyprintk
usb start
ext2load usb 1:1 0x00800000 /uImage
ext2load usb 1:1 0x01100000 /uInitrd
bootm 0x00800000 0x01100000

to see if you can get more debug info.
