  * sudo fdisk -u /dev/mmcblk0
  
  * Print the current partitions with 'p'
  
  * Make note of the starting and ending sectors of the second partition

  *<code>
   Device            StartCHS    EndCHS      StartLBA   EndLBA      Sectors   Size    Id   Type
   /dev/mmcblk0p2    1023,3,16   1023,3,16   172032     204799      32768     16.0M   83   Linux
   </code>
   
  * Delete the second partition with 'd'

  * Create a new second partition with 'n' with same starting sector (StartLBA) and higher ending sector
      * You might want to reserve some space (e.g. 1 or 2 GB) for swap space on devices with low amount of memory.\\ This is only needed if you expect to run out of memory e.g. during compiling a large program.\\ Normally this is not needed.

  * Below the old and new second partition below each other.

   </code>\\ You can delete (d) and re-create (n) the partition at this point if needed. 
 

  * Write the new created second partition with 'w'

  * Reboot to use the new partition table.
      * sudo reboot

  * Enlarge the second partition to the new size with:
      * sudo resize2fs /dev/mmcblk0p2

  * Verify the result with:
      - df -hT\\ To actually configure and use the swap partition a few additional steps are needed. Current swap size can be verified with:
      - free
