To place a new u-boot image in the alternate flash bank and then boot
with that new image temporarily, use this:
tftp 1000000 u-boot.bin
- erase ef780000 ef7fffff
- cp.b 1000000 ef780000 80000
+ erase ef740000 ef7fffff
+ cp.b 1000000 ef740000 c0000
Now to boot from the alternate bank change the SW4[8] from 0 to 1.
To program the image in the boot flash bank:
tftp 1000000 u-boot.bin
protect off all
- erase eff80000 ffffffff
- cp.b 1000000 eff80000 80000
+ erase eff40000 ffffffff
+ cp.b 1000000 eff40000 c0000
