The previous u-boot version I use is U-boot 1.2.0, an ancient version. So I upgrade the u-boot to 2009-08. The platform is MPC8247. About build warnings, some warnings in printf for not proper type, and yes, I get the 64-bit printf warning :
nand_util.c:45:2: warning: #warning Please define CONFIG_SYS_64BIT_VSPRINTF for correct output!
After I change the loff_t from long long to unsigned long, it works fine now.

My u-boot version is u-boot-2009-08. In my U-boot, after I entered "nboot 800000 0 0", the following messages shows:

The image in nand is written in linux 2.6.22 using nandwrite -p /dev/mtd3 uImage This command works fine before.
What u-boot verison is "before"? What platform?
Are you getting any build warnings about 64-bit printf, BTW?
I looked into the source tree, and u-boot should read out the first block in my nand flash to show the information of my image. But, after that, U-boot just think all the following blocks are bad blocks, so it read failed.
Perhaps u-boot and your version of Linux disagree about NAND layout.
