USB drive, TF card mount

When a USB flash drive or TF card is inserted, the storage device will be recognized as a node similar to /dev/sdb1 or /dev/mmcblkp1, which is the same as in the desktop PC Linux environment.

The file system supports FAT, FAT32, EXT2/3/4, NTFS. EC-A1684JD4 does not support automatic mounting, so mount needs to be manually mounted. After completing the data writing, please use sync or umount in time, and please use the sudo poweroff command when shutting down to avoid violent power-off and shutdown to avoid data loss.

USB drive mount

Insert the USB drive, use dmesg to know the sd device corresponding to the USB drive:

Mount the USB drive:

# create mount directory
mkdir disk
# mount
sudo mount /dev/sdb1 disk
# View the files in the USB drive
ls disk

TF card mount

The TF card mounting is similar to the USB drive, use dmesg to know the mmcblk device corresponding to the TF card:

[16220.776440] [4] mmcblk1: p1

# create mount directory
mkdir media
# mount
sudo mount /dev/mmcblk1p1 media
# View the files in the TF card
