Alpine Linux Install Script for Allwinner H3 single board computers

burnimg.sh

#!/bin/bash
#this script grabs dependencies for the armhf alpine image for H3 allwinner chips
#you will need to modify  your script.bin with the fex files and sunxi-tools
#use fex2bin to modify and create and place it in the H3-Distro directory

#TODO: check dependencies for dosfstools sunxi-tools

echo "run this script with your sd card as the argument"
echo "if unsure, check with: ls /dev/sd*"
echo "use only the last part, like: ./burnimg.sh sdh"
