各位前辈，小弟在做uboot移植过程中，利用tekkamanninja-u-boot-2011.06-for-MINI6410生成的u-boot-nand.bin，写入tiny6410的nandflash，可是 不能启动啊，不知是否遇到过此问题，如何解决？
详细操作如下：
1、实验环境：
u-boot代码：tekkamanninja-u-boot-2011.06-for-MINI6410-d9a2446.zip
编译工具：arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz
supervivi板本：superboot-20110722.rar
2、操作步骤：
（1）编译uboot：
make CROSS_COMPILE=arm-linux- mini6410_config
make CROSS_COMPILE=arm-linux-
（2）在uboot根目录下生成u-boot-nand.bin，利用supervivi写入nand flash。从SD卡启动，在spuerboot菜单下选择[f]，清除Flash；再选择[v]，下载u-boot-nand.bin，现象如下：

（3）断电，将启动模式换成从nand启动，上电，结果：串口无任何输出信息。
（4）利用步骤（1）、（2）将tiny6410自带的uboot（u-boot-mini6410-bin-20110601.zip编译生成）下载到nand flash，可以正常启动uboot：
