简介Widora出厂固件默认支持了VFAT,EXFAT,EXT4等文件系统格式。如果U盘或TF卡不是这几种格式,请格式化成此种格式。
一般U盘对应的设备文件在/dev/下sda,sdb,sdc这些,而SD卡则是mmcblk0,mmcblk0p1等。
挂载插入U盘,默认串口控制台会打印如下: root@Widora:/# [ 2531.690000] usb 1-1: new high-speed USB device number 2 usingm[ 2531.840000 usb-storage 1-1:1.0: USB Mass Storage device detected [ 2531.850000 scsi host0: usb-storage 1-1:1.0 [ 2532.850000 scsi 0:0:0:0: Direct-Access SanDisk Cruzer Blade 1.27 P6[ 2532.860000 sd 0:0:0:0: [sda 15330304 512-byte logical blocks: (7.84 GB/7.3)[ 2532.870000 sd 0:0:0:0: [sda Write Protect is off [ 2532.870000 sd 0:0:0:0: [sda Write cache: disabled, read cache: enabled, doA[ 2532.900000 sda: sda1 [ 2532.910000 sd 0:0:0:0: [sda Attached SCSI removable disk [ 2533.190000 FAT-fs (sda1): Volume was not properly unmounted. Some data may .U盘会自动挂载至“/tmp/mounts/“目录: root@Widora:/# cd /tmp/mounts/ root@Widora:/tmp/mounts# ls USB-A1 此时进入USB-A1可以看到U盘的文件列表: root@Widora:/tmp/mounts# cd USB-A1/ root@Widora:/tmp/run/mountd/sda1# ls test 1.mp3 TF卡挂载同理,也会挂载至”/tmp/mounts/“目录。
