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。

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

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。
