Solve the problem that the arm Development Board cannot mount a USB flash disk

Insert the USB flash drive into the Development Board. A prompt is displayed, but it is not displayed. The folder udsik is available in the manual but cannot be found.

Solution:

1. CD/Dev, we can see sd1. This is the prompt SD: sda1 when inserting a USB flash drive.

2. Create node mknod sda1 B 8 1 in the dev directory

3. CD/mnt/

4. mkdir udisk

5. mount Mount-T vfat/dev/sda1/mnt/udisk

If no message is displayed, the mounting is successful. You can view the files in the USB flash drive by entering/mnt/udisk.
