USB drive, TF card mount

When a USB drive or TF memory card is inserted, the storage device will be recognized as a node, typically represented as /dev/sdb1 or /dev/mmcblkp1, analogous to the Linux environment on a desktop PC.

The file system supports FAT, FAT32, EXT2/3/4, NTFS. 3DV-EdgeAI-32 does not support mounting, so you need to mount it manually. After writing data, please use the sync or umount command to safely disconnect, and use the sudo poweroff command to perform system operation to avoid data corruption due to sudden power failure.

Mounting a USB drive

Insert the USB drive and use the dmesg command to identify the corresponding device (e.g., sd):

[15460.953423] [5] sdb: sdb1

Then follow the steps below:

(1) Create a mount point:

mkdir disk

(2) Mount the USB drive:

sudo mount /dev/sdb1 disk

(3) List files on the USB drive:

ls disk

Mounting a TF Card

The mounting a TF card is similar to mounting a USB drive. Use the dmesg command to obtain information about the corresponding mmcblk device:

[16220.776440] [4] mmcblk1: p1

Then follow the steps below:

(1) Create a mount point:

mkdir media

(2) Mount the TF card:

sudo mount /dev/mmcblk1p1 media

(3) List files on the TF card:

ls media
