各位大侠，我开发板是s3c2410，内核选的是linux2.6.24.7，根文件系统是做的是jffs2的，现在系统能跑起来，可是在启动信息里出现了以下的信息，而且是出现了很多次，这是为什么啊？
Empty flash at 0x0172da10 ends at 0x0172dc00
jffs2_scan_dirent_node(): Node CRC failed on node at 0x017889e4: Read 0xffffffff
, calculated 0xdfe1f07b
具体的启动信息如下：
Press Return to start the LINUX now, any other key for vivi
