1、spi nor版本u-boot
注：没有基础的朋友，请自行在论坛上查找刷写方法，如果没有特别要求最好不要随意更换自己的Uboot。
自己编译的版本，找了一些资料就是没有找到让这个uboot支持内存256MB，这个版本只支持128MB内存。
2、ram版本u-boot
这个版本大家随意使用没有危险，载入地址0x81000000
（1）在u-boot中使用
tftp 0x81000000 dw33d_u-boot_ram.bin
go 0x81000000
（2）在breed中使用
wget 0x81000000 http://192.168.1.x/dw33d_u-boot_ram.bin (x为你电脑的ip)
mem crc32 0x81000000 0x31078 （我也不知道为什么breed中使用ram版的uboot为什么需要校验下，如果不校验有较大概率死机）
boot raw 0x81000000
3、nand版本的u-boot
可以将dw33d的nor flash的第10脚与第16脚短接后上电，就能进入nand启动模式。
