2#li_thomas谢谢回复！
EBI部分每个片选区域为256M，那么我如果寻址超过这256M，linux系统会不会去其他外设寻址呢？我试了下，不修改驱动，能进入linux shell界面，但不断打印了大量的jffs2错误信息，麻烦你能帮我看下吗？谢谢！！！
主要为这几种信息：
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x149623e8: 0x4387 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x149623ec: 0x4387 instead
Further such events for this erase block will not be printed
jffs2_scan_inode_node(): CRC failed on node at 0x149627c4: Read 0x79c6fb8d, calculated 0xf366c483
