BeagleBone Initilization Scripts

[calzon65]

Here are a few scripts I use to partition an SD card, format/upload to the SD card, and initialize the eMMC memory in a BeagleBone Black. With some slight modifications, the scripts will probably work on other hardware platforms.

Partition SD Card:
$this->bbcode_second_pass_code('', '# This script partitions SD media for use as a boot device for a BeagleBone
# or BeagleBone black. The first partition (boot) is sized at 16MB. If you
# want a larger partition, change the code below (look for +16M). This script
# assumes the device you want to partition is located at /dev/sd?. Make sure
# you verify the correct device name before proceeding.

DEVICELIST=`ls /dev/sd? 2> /dev/null | sed s:/dev/::`
if [ -z "${DEVICELIST}" ]; then
echo "ERROR: No /dev/sd? devices"
exit
fi

clear
echo Device Choices: $DEVICELIST
echo
while true
do
read -p "Enter device name: " DEVICECHOICE
if echo "$DEVICECHOICE" | grep -q "$DEVICELIST"
then
break
else
echo "ERROR: You entered an invalid device name."
fi
done

echo
while true
do
read -p "Are you sure you want to use /dev/$DEVICECHOICE (answer yes or no)? " ANSWER
case $ANSWER in
yes ) break;;
no ) exit;;
* ) echo "ERROR: Please answer yes or no.";;
esac
done

fdisk /dev/$DEVICECHOICE << EOF

Format/Upload ArchLinux to SD Card:
$this->bbcode_second_pass_code('', '# This script is used to create a new (clean) install of ArchLinux for the BeagleBone or
# BeagleBoneBlack on a microSD card. Verify your media devices before you proceed. This
# script assumes your media device is /dev/sd?. Ensure you have partitioned (fdisk) your
# media before proceeding. You will need two partitions. The first partition does not need
# to be large, but needs to be set to bootable and must be type 'e' which is FAT 16.
# The second partition is a normal Linux partition, probably ext4. If you can't mkfs.vfat,
# download the dosfstools (pacman -Sy dosfstools).
