JFFS2文件系统警告
各位大神,我用的是TI的AM3505,内核是2.6.37,文件系统是JFFS2,从USB复制文件到本地后会出现如下打印信息,
[ 44.057525] jffs2_flush_wbuf(): Write failed with -5
[ 44.063507] Write of 1302 bytes at 0x023d14d8 failed. returned -5, retlen 0
[ 44.070953] Not marking the space at 0x023d14d8 as dirty because the flash driver returned retlen zero
这是怎么回事,有时候复制后会直接系统崩溃,打印信息如下
