标题: Uboot nand 错误。急需请教！！！！！！！
通过DNW + USB, 将uboot下载到RAM，后启动暂时的uboot.
无论是输入nand scurb 还是在 fastboot下向ROM中再次烧写uboot.
都提示  no devices available.

为什么NAND  显示 0 MB

DNW输出信息如下：
1.
U-Boot 1.3.4-dirty (Nov 15 2012 - 16:29:10) for x210

CPU:  S5PV210@1000MHz(OK)

      APLL = 1000MHz, HclkMsys = 200MHz, PclkMsys = 100MHz

MPLL = 667MHz, EPLL = 96MHz

         HclkDsys = 166MHz, PclkDsys = 83MHz

         HclkPsys = 133MHz, PclkPsys = 66MHz

         SCLKA2M  = 200MHz

Serial = CLKUART

NAND: 0 MB
