USB Drive, TF Card, SSD Mounting EC-A1688JD4 supports a range of storage device interfaces (PCIE, SATA, USB, TF card). When a storage device is inserted, it will be recognized as "/dev/sdb1", "/dev/nvme0n1p1", or "/dev/mmcblkp1", similar to nodes in a desktop PC Linux environment. The file system supports FAT, FAT32, EXT2/3/4, and NTFS. The EC- A1688JD4 does not support automatic mounting, so manual "mount" is required. After completing data writing, please promptly use "sync" or "umount" operations. When shutting down, please use the "sudo poweroff" command to avoid a forced power-off, which may lead to data loss. USB Drive (SATA Hard Drive) Mounting Insert the USB drive (SATA hard drive) and use "dmesg" to find the corresponding "sd" device: [15460.953423] [5] sdb: sdb1 Mount the USB drive (SATA hard drive): # Create mount directory mkdir disk # Mount sudo mount /dev/sdb1 disk # View files in the USB drive (SATA hard drive) ls disk TF Card Mounting Mounting the TF card is similar to the USB drive; use "dmesg" to find the corresponding "mmcblk" device: [16220.776440] [4] mmcblk1: p1 Mount the TF card: # Create mount directory mkdir media # Mount sudo mount /dev/mmcblk1p1 media # View files in the TF card ls media PCIE SSD Mounting Generally, the mountable PCIE node is: /dev/nvme0n1p1. Mount the PCIE SSD: # Create mount directory mkdir nvme_dir # Mount sudo mount /dev/nvme0n1p1 nvme_dir # View files in the PCIE SSD ls nvme_dir
