大家好，最近我在micor2440上开发东西，用uboot1.1.6，是我以前移植的，支持64M 的flash，现在我把ubo0t写到norflash中，然后从norflash中启动，可以识别256M的nandflash，然后我tftp下载内核和文件系统，内核可以正常bootm，可是却发现不能正确加载文件系统，我现在就想不明白，内核能启动，说明uboot支持对256Mflash的读写，可是为什么文件系统却不行能？nand write.jffs2 nand write.yaffs分别是写内核和文件系统命令，加文件系统和不加文件系统启动信息是一样的，启动信息如下：

哪位高手知道说明原因啊？我也知道uboot不支持2048页的nandflash，可是内核启动了啊，就是这点搞不明白
