sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot "board"

ssh into BeagleBone

 (R.Nelson, 2012)



apt-get update

apt-get upgrade


apt-get install libncurses5-dev lzma make gcc patchutils libproc-processtable-perl

create a swapfile

mkdir -p /var/cache/swap/ sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024 sudo 

chmod 0600 /var/cache/swap/swapfile 
mkswap /var/cache/swap/swapfile
swapon /var/cache/swap/swapfile

get sources and BeagleBone patches

mkdir /home/stuff

cd /home/stuff

wget http://rcn-ee.net/deb/precise-armhf/v3.2.21-psp16/defconfig

wget http://rcn-ee.net/deb/precise-armhf/v3.2.21-psp16/patch-3.2-psp16.diff.gz

mkdir /home/linux

cd /home/linux

wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.2.tar.bz2

tar xjf linux-3.2.tar.bz2 

cd linux-3.2

zcat /home/stuff/patch-3.2-psp16.diff.gz | patch -p1

cp /dir/downloaded/defconfig .config

edit the em28xx driver (Makarov, 2011)

cd drivers/media/video/em28xx/

sed -i 's/height >>= norm_maxh(dev)/height = norm_maxh(dev) >> 1/' em28xx-core.c

cd /home/linux/linux-3.2

make menuconfig

Device drivers > USB support > disable DMA (always use PIO)

make

make modules_install

apt-get install motion

Getting a decent picture out of the lifecam, but timeouts from the em28xx.


I AM STUCK NOW. TIME TO ASK THE INTERNETS.




Answer = use a syntek device!

This card is currently producing a 720x576 image in motion on the BeagleBone running ubuntu 12.04 - and no mucking about with the kernel.
