mw.b 0x80000000 0xff 0x1c0000
tftp 0x80000000 u-boot-vrreader-am35.bin
nand erase 0x80000 1c0000
nand write 0x80000000 0x80000 1c0000

Kernel / FS Loading

• make sure kernel size is < 0x300000 or change script below!
• make sure ETHADDR is set correctly!

setenv ethaddr 00:50:c2:7c:57:00
setenv get_kernel nand read.i 0x80000000 0x280000 0x300000
