研发客服接上面（5）在串口终端出现如下：
U-Boot 1.1.6 (Nov 25 2009 - 22:15:51)
DRAM: 64 MB Flash: 1 MB NAND: 64 MiB *** Warning - bad CRC, using default environment
还存在警告，这个警告不是错误，而是新的环境变量起作用，
只要在OPENJTAG但是我在下面输入saveenv、reset之后还存在警告。。。
网友henry.li说:估计是你的环境变量保存的位置不正确，环境变量实际上没有保存。 我想想还是很有道理的，否则不会保存不上。。。。也就是没有保存到nandflash上去。。。于是再利用韦东山的补丁u-boot-1.1.6_OpenJTAG_env_on_nand.patch又打上去。。。这个补丁就可保存变量到nandflash上去，这下再试下。。。第一次上电，在dnw下显示如下：
U-Boot 1.1.6 (Nov 27 2009 - 19:33:59)
