飞凌2440开发板挂载SD卡时出现错误,请教各位
飞凌2440开发板在挂载SD卡(2G)时出现如下错误:插上SD卡时,超级终端显示:# mmc0: host does not support reading read-only switch. assuming write-enable.
mmcblk0: mmc0:aaaa SD02G 1931264KiB
/dev/mmc/blk0:<3>mmcblk0: error 2 transferring data

当输入挂载命令时显示:

当我换成1G的MMc卡时,插上后,超级终端根本一点反应也没有,在dev目录下没有mmc文件,各位给说说,是怎么回事啊 你用的哪个内核? 回复 2# 飞凌-alexlee
2.6.18内核的啊,板子自带的,在wince下就能读写操作!
