为了更新u-boot,需要启动tftp服务器.需要设置PC机的网关,IP等. 如下：
在Federo 4.0中点击运用程序->系统设置->网络,点击设备Tab,双击Ethernet,选择静态设置IP,设定
IP: 192.168.1.2
掩码: 255.255.255.0
网关: 192.168.1.1
保存后,则点击激活,则在u-boot下可以ping通192.168.1.2
[ makethyme@localhost.com ]# ping 192.168.1.2
testid = 57
rBWSCON 0x22111110
rBWSCON 0x2211D110
rBANKCON3 0x00001F7C
testid = 630e
host 192.168.1.2 is alive
先将u-boot下载到RAM中：
[ makethyme@localhost.com ]# tftp 0x33000000 u-boot.bin
testid = 630e
rBWSCON 0x2211D110
rBWSCON 0x2211D110
rBANKCON3 0x00001F7C
testid = 630e
TFTP from server 192.168.1.2; our IP address is 192.168.1.8
Filename 'u-boot.bin'.
Load address: 0x33000000
Loading: #########################
done
Bytes transferred = 125156 (1e8e4 hex)
再使用nand erase/nand write将u-boot烧写到flash中。
[ makethyme@localhost.com ]# nand erase 0x0 0x20000
in do_nand
NAND erase: device 0 offset 0, size 131072 ...
OK
[ makethyme@localhost.com ]# nand write 0x33000000 0x0 0x20000
in do_nand

当移植完毕Linux后，将zImage拷贝到u-boot/tools下，使用工具用工具mkimage生成uImage
mkimage -A arm -O linux -T kernel -C none -a 30008000 -e 30008000 -n linux-2.6.22 -d zImage uImage
然后将zImage拷贝到tftp的制定目录/tftpboot下
[ makethyme@localhost.com ]# tftp 0x33000000 uImage
rBWSCON 0x22111110
rBWSCON 0x2211D110
