Before you start

Using the prebuilt image we provided to test hardware.

How to make a bootable SD card

1. Insert the SD card into your computer, if using virtual machines, please make sure the SD card mounted to the Linux operating system.

2. Confirm the SD card mount point “/dev/sdX”, usually it should be “/dev/sdb”. You can use this command to find out what the “X” is in the Linux system.

$ sudo fdisk –l

3. Copy the file “prebuilt-angstrom-bbb-lcd-audio-exif-2014-12-25.tar.gz“ somewhere(such as $HOME).

4. Extract the file “prebuilt-angstrom-bbb-lcd-audio-exif-2014-12-25.tar.gz“

$ tar xzvf prebuilt-angstrom-bbb-lcd-audio-exif-2014-12-25.tar.gz

5. Go to the folder “prebuilt-angstrom-bbb-lcd-audio-exif-2014-12-25“

$ cd ~/prebuilt-angstrom-bbb-lcd-audio-exif-2014-12-25

6. Flash the Angstrom OS to the SD card

$ sudo ./mksdcard.sh --device /dev/sd<?>

Notes: The SD card should be at least 2GB, and you’d better to use Sandisk Class4 level SD card or or above.
