2020年02月27日 | SmartARM3250 CF卡使用说明

如果SmartARM3250的CF卡不能使用，请参考下面的步骤来解决。

（1）检查内核版本是否已经支持CF卡，请查看有无drivers/ide/arm/smartarm3250-ide.c以及drivers/ide/arm/smartarm3250-ide.h文件，如果没有，请点击下载新版内核：

SmartARM3250内核V1.05  http://u.115.com/file/f7fe72fc73

其中/file/后面的为文件提取码，如果遇到已经过期的错误提示，请联系技术支持，发邮件到技术支持邮箱。

（2）检查配置文件，主要看ATA、IDE、IDEDISK、VFAT等有没有被选中，如果没有，请选中，当然，为了简便，可以下载附件的配置文件。

 覆盖原来的默认配置文件或者直接作为.config文件，然后重新编译内核。

（3）更新内核，插入CF卡，启动系统。先看启动信息中有无发现CF卡，进入Shell后，先查看/proc/partitions文件，看看有无CF卡的分区，一般为hda或者hda1等，根据卡的分区情况而定。

（4）然后进行挂载，如果是FAT/FAT32格式，可在命令中指定-t vfat进行挂载。
