you should at least copy to 0xbf020000, that's where your flash is located.

you are using wrong addresses.. you see that the first erase gone wrong?? then you did a second erase with the right address.. but you also have to do the cp.b with that address!

erase 0xbf020000 +0x3c0000
cp.b 0x81000000 0xbf020000 0x3c0000
