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 .

Compatibility

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.

Installation

Make sure device is powered off before inserting SD card!

Results

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

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

If you are unable to format the memory card using other means, it is possible to do it directly on {{{name}}} device.

Pre-requisites

Device must have WAN access.
SD card must be recognized by the filesystem.

Procedure

Connect to device's [[{{{name}}}_Maintenance#CLI | CLI]].
Use command ls /dev/ | grep mmc to display recognized memory cards:

root@Teltonika-{{{name}}}:~# ls /dev/ | grep mmc

mmcblk0

mmcblk0p1 ← SD card

Once confirmed the SD is recognized, we may start the formatting procedure:
Run commands opkg update and opkg 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:

root@Teltonika-RUT955:~# mkfs.ext2 /dev/mmcblk0p1

mke2fs 1.45.6 (20-Mar-2020)

/dev/mmcblk0p1 contains a ntfs file system labelled '64gb'

Creating filesystem with 15132670 4k blocks and 3784704 inodes

Allocating group tables: done 
                           
Writing inode tables: done
                      
Writing superblocks and filesystem accounting information: done

Reboot the {{{name}}} device and refer to [[{{{name}}}_SD_Card#Results | Results]] section

Note: The Writing inode tables section might take a long time depending on the size of your SD card (10+ minutes with 64GB SD).
