You can activate several devices by flashing and cloning your sd card. This article explains how to clone your SD card on linux.
Note: You will need to undertake a couple of steps beforehand. Take a look at our tutorial.
- Insert the SD card into your PC, through a USB or a built-in card reader.
- Open Terminal and enter the following command:
sudo fdisk -l
This will list all drivers on your system.
- Search in this list for the drive name of the inserted SD card.
In our example it is: sdd.
- If you want to write the backup to a backup drive instead of the system drive, you have to first mount this drive.
In our example it is: sdb1.
- Create a mount point:
sudo mkdir /mnt/sdb1
- Mount the backup drive (sdb1) to this point:
sudo mount -t auto /dev/sdb1 /mnt/sdb1
- To write the image to your backup drive use the dd command. The current date will be attached to the file name:
sudo dd if=/dev/sdd of=/mnt/sdb1/emteriaBackup'date +%d%m%y'.img
- Insert the new SD card into your PC.
- Before you restore the image, it is important to make sure that the SD card’s partitions are unmounted. To verify this, open the Terminal, and execute the following command:
sudo mount | grep sdd
Here sdd is the new SD card’s device name.
- Use the dd command to write the image to your new SD card:
sudo dd if=/mnt/sdb1/emteriaBackup'date +%d%m%y'.img of=/dev/sdd
