 ====== SD Card Creation ======
+This section of the Wiki describes how to create an SD card for Oxygen by formatting the card, creating disk partitions, and copying the file systems.
 ===== Format the SD card =====
+In Linux, start fdisk by running
+<code>
+sudo fdisk /dev/mmcblk0
+</code>
-sudo fdisk /dev/mmcblk0
+where // /dev/mmcblk0 // is the base device of the SD card in the computer.
-where /dev/mmcblko is the base device of the sd card in the computer
+In fdisk, complete the following steps in numerical order:
-Whit in fdisk
+  - Press //''p''// and then //''Enter''// to print the partition table and make sure the device is the SD card.
-p
+  - Press //''n''// and then //''Enter''// to add a new partition.
-to print and make sure the device is the sd card
+  - Press //''p''// and then //''Enter''// to designate the new partition as the primary partition.
-n
+  - At the //''Partition number''// prompt, press //''Enter''// to use the default partition number 1.
-new partition
+  - At the //''First sector''// prompt, press //''Enter''// to use the default first sector size of 2048.
-p
+  - At the //''Last sector''// prompt, enter //''+1G''// and press //''Enter''// to set the partition size as 1 GB.
-Primary
+  - Press //''t''// and then //''Enter''// to change the partition type.
-Enter for default number
+  - Press //''c''// and then //''Enter''// to select vfat32 as the partition type.
+  - Press //''n''// and then //''Enter''// to create another partition.
+  - Press //''Enter''// to select the default partition type of primary.
+  - At the //''Partition number''// prompt, press //''Enter''// to use the default partition number 2.
+  - At the //''First sector''// prompt, press //''Enter''// to use the default first sector size of 2099200.
+  - At the //''Last sector''// prompt, press //''Enter''// to use the default last sector size.
+  - Press //''w''// and then //''Enter''// to write the new partitions to the SD card.
-+1G
+===== Create the file systems =====
-for last sector
+First, create the boot file system on the 1 GB partition by running the following:
-n
+<code>
-t
-change the type
-c
-vfat32
-n
-for new partiation
-enter
-enter
-w
-to write the partition table
-===== Create the file systems
- =====
 sudo mkfs.vfat -n BOOT /dev/mmcblk0p1
+</code>
+Then, create the main file system on the main partition by running:
+<code>
 sudo mkfs.ext4 -L root /dev/mmcblk0p2
+</code>
-eject the sdcard and put it back in the computer
+Next, eject the SD card, remove it, and then put it back in the computer.  This step is important to get the OS to enumerate the card with these new file systems.
-Copy data to the sdcard
+===== Copy data to the SD card =====
-cd to the buildarea/temp/deploy/images/oxygen
+Change directory to //''buildarea/temp/deploy/images/oxygen''//, or where you have downloaded the image.  Then, run the following:
+<code>
 cp download.* /media/user/BOOT/
 cp boot.bin /media/user/BOOT/
 cp Image /media/user/BOOT/
 cp oxygen.dtb /media/user/BOOT/
+sudo tar -xf rwt-sdr-image-oxygen.tar.gz -C /media/user/root/
- sudo tar -xf rwt-sdr-image-oxygen.tar.gz -C /media/user/root/
 sudo tar -xf
+</code>
