This chapter provides a description on how to correctly insert a SD card into a {{{name}}} device.
The information in this page is updated in accordance with firmware version [[Media:{{{series}}}_R_00.07.02_WEBUI.bin|{{{series}}}_R_00.07.02]].
Compatibility[edit source]
Before installation, make sure your SD card is compatible with {{{name}}} devices:
- Maximum supported (tested) SD card capacity is 64GB.
- Supported (tested) formats are: FAT32, NTFS, ext2, ext3, ext4.
- SD cards with a fixed 1.8V voltage are not supported. Make sure your memory card supports 3.3V by referring to manufacturer's documentation.
- The device is compatible only with microSD size memory cards.

Results[edit source]
Once device is booted up with an SD card installed, you can confirm it is recognized by navigating to [[{{{name}}}_USB_Tools#Mounted_File_Systems | USB Tools]] WebUI page. Under Mounted File Systems the SD card should be visible:
You may now use various functionality found in [[{{{name}}}_USB_Tools | USB Tools]] with the SD card instead of a USB device.
If you are having trouble with the device recognizing your SD card, please refer to the Troubleshooting section below.
Troubleshooting[edit source]
- Double check the SD card is [[{{{name}}}_SD_Card#Compatibility | compatible]] with {{{name}}} devices.
- Make sure the SD card is not corrupted. We recommend formatting it before first installation.
Formatting SD card using device[edit source]
If you are unable to format the memory card using other means, it is possible to do it directly on {{{name}}} device.
Pre-requisites[edit source]
- Device must have WAN access.
- SD card must be recognized by the filesystem.
Procedure[edit source]
- Connect to device's [[{{{name}}}_CLI | CLI]].
- Use command
ls /dev/ | grep mmc
to display recognized memory cards: - Once confirmed the SD is recognized, we may start the formatting procedure:
- Run commands
opkg update
andopkg install e2fsprogs
to download required tools. - Unmount the SD card with command
umount /dev/mmcblk0p1
- Start formatting with command
mkfs.extX /dev/mmcblk0p1
where X is either 2 (for ext2 format), 3 (for ext3 format) or 4 (for ext4 format). - A successful format procedure should look like this:
- Reboot the {{{name}}} device and refer to [[{{{name}}}_SD_Card#Results | Results]] section
root@Teltonika-{{{name}}}:~# ls /dev/ | grep mmc
mmcblk0
mmcblk0p1 ← SD card
root@Teltonika-RUT955:~# mkfs.ext2 /dev/mmcblk0p1
mke2fs 1.45.6 (20-Mar-2020)
/dev/mmcblk0p1 contains a ntfs file system labelled '64gb'
