My u-boot version is u-boot-2009-08. In my U-boot, after I entered "nboot 800000 0 0", the following messages shows:
Loading from NAND 1GiB 3,3V 8-bit, offset 0x0 Image Name: Linux-2.6.22.sac.rd Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1045865 Bytes = 1021.4 kB Load Address: 00000000 Entry Point: 00000000 NAND read from offset ffffffff failed 0 ** Read error The image in nand is written in linux 2.6.22 using nandwrite -p /dev/mtd3 uImage This command works fine before. 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. But when booting linux using nfs with linux image in norflash, there is no bad block shown when linux scan nand for bad blocks. How could this happen? I have no idea right now.
