Flashing SD-card

Find the device

lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0   3,7G  0 disk 
├─mmcblk0p1 179:1    0    11M  0 part /media/christoph/74C5-8858
└─mmcblk0p2 179:2    0   3,7G  0 part

So our SD-card is /dev/mmcblk0.

Unmount its partitions

sudo umount /dev/mmcblk0p1
sudo umount /dev/mmcblk0p2

Optional: Clear the SD-card by recreating the partition table. Fdisk will also tell you the sector size.
```
sudo fdisk /dev/mmcblk0
--> o
--> w 
```
Copy the image onto the device using dd. When your sector size is 512bytes, you can leave out the "bs=1M" in the following command.
```
sudo dd if=./wandboard-all-ubuntu-16.04-sdcard-20160525.img of=/dev/mmcblk0 bs=512 status=progress && sync
```
Checking file system
```
sudo fsck /dev/mmcblk0p2
```
