1/1/2013 Happy New Year!

Today I am thinking that this will be used as a car computer.

I got a heavy duty 7 port USB hub for it, a nice cast al box, and now I want to make it work with my Lilliput 7" DisplayLink monitor.

To do that I will need to compile a kernel (ugh! back to doing that again!)

Distro

Try the arch linux option. Gave up on it and went with Debian. Still the best.

DisplayLink kernel build

Some help with kernels and DisplayLink http://karuppuswamy.com/wordpress/2012/08/17/lilliput-displaylink-usb-monitor-um-70-17e902a9-with-raspberry-pi-on-raspbian/

Following Mitchtech kernel compile instructions with a few variations. I am using Linux Mint 14 as my build host. This installs the newest (4.7) compiler and creates symlinks. This step (building a working ARM tool chain) used to take days to figure out. Ah, progress! I love the Linux world I live in!

sudo apt-get install gcc-arm-linux-gnueabi git-core ncurses-dev

Fetching code

mkdir -p ~/src/raspberrypi
cd ~/src/raspberrypi
git clone https://github.com/raspberrypi/tools.git
git clone https://github.com/raspberrypi/linux.git
cd linux
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- bcmrpi_cutdown_defconfig
# enabled the DisplayLink module and disable many things I will never use
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- menuconfig
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -k -j5
mkdir ../modules
make modules_install ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- INSTALL_MOD_PATH=../modules/
cd ../tools/mkimage/
# Create kernel.img
./imagetool-uncompressed.py ../../linux/arch/arm/boot/Image
cp kernel.img /media/bwilson/8B12-9112/
sudo rm -rf /media/bwilson/29b6c2f5-5469-49f2-abd5-daa9149021cc/lib/modules/
sudo rm -rf /media/bwilson/29b6c2f5-5469-49f2-abd5-daa9149021cc/lib/firmware/
sudo cp -a lib/modules/ /media/bwilson/29b6c2f5-5469-49f2-abd5-daa9149021cc/lib
sudo cp -a lib/firmware/ /media/bwilson/29b6c2f5-5469-49f2-abd5-daa9149021cc/lib

Zoom zoom away we go. Put SD card in Pi. Connect monitor and boot. Worked on first try for me! Fabulous.

X11

Before diving in to the above instructions on how to get X11 going, I typed "startx" and it came up! Okay. Moving on. I need the touchscreen to work. It acts like it works but is not calibrated. I am using a mouse at the moment.

Wifi

Bluetooth keyboard
