Linux for CM-iGLX module is based on Gentoo Linux 2006.1. The
 
[http://www.compulab.co.il/iglx/download/iglx-linux.zip CompuLab
 
Linux package for CM-iGLX] includes ready to run USB NAND flash image,
 
Linux kernel configuration and source code patches, portage tree used
 
to create the image, packages database archive, and graphics and
 
touchscreen driver sources.  The [[CM-iGLX Linux:Getting started]] page gives brief introduction on how to setup and start
 
using the run-time Linux image. Here we describe in more detail image
 
structure, and also provide guidelines for image modification, and even
 
creation of your own Gentoo Linux for CM-iGLX.
 
 
 
The Linux image we provide is made as generic as possible. It includes
 
more then 200 packages, among them KDE, mplayer, thttpd web server,
 
and Samba Windows connectivity suite.
 
Still, it is impossible to fit into 512Mbytes each and every Linux
 
application and make it suitable for all possible designs based on
 
CM-iGLX.
 
 
 
Deafult image for CM-iGLX leaves moderate amount of the free space to
 
the user application. If you don't need printer support you can run
 
{{cmd|1=remove.printers}} script that will free ~30Mbytes. Moreover, if you're
 
not planning to use KDE, you can run {{cmd|1=remove.kde}} script that will
 
free more than 100Mbytes.
 
 
 
== Package contents ==
 
 
 
The CompuLab Linux package for CM-iGLX contains the following
 
components:
 
 
 
=== gentoo.img.gz ===
 
 
 
{{filename|1=gentoo.img.gz}} is ready-to-run disk image with Linux for CM-iGLX. It
 
can be installed onto the on-board NAND flash as described at [[CM-iGLX Linux:Getting started|Getting started]] page.
 
The {{filename|1=gentoo.img}} is a complete disk image, containing partition table
 
and two partitions: {{filename|1=/boot}} and {{filename|1=/}}. The {{filename|1=/boot}} partition is
 
~10Mbytes and it is used to store bootloader and Linux kernel.
 
The rest of the image is the {{filename|1=/}} partition containing root filesystem.
 
Each of the partitions can be loop-mounted and modified on the host
 
workstation, e.g. using {{cmd|1=image_mount.sh}} utility.
 
 
 
=== kernel ===
 
 
 
{{filename|1=kernel}} directory contains Linux kernel binary
 
({{filename|1=vmlinux-2.6.20-cm-iglx}}), a copy of {{filename1=.config}} used to build the
 
kernel ({{filename|1=linux-2.6.20.config}}) and the modification of the kernel
 
source made to support CM-iGLX devices. These modifications are
 
available as patch vs. standard
 
[http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2 Linux
 
kernel 2.6.20]. ({{filename|1=linux-2.6.20.pacth}})

Linux Kernel and Drivers
 
------------------------
 
Kernel compilation
 
05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)[[User:Mike|Mike]]
 
Linux kernel for CM-iGLX is based on version 2.6.20 with
 
addition of GeodeLX frame buffer drivers from AMD, and drivers for
 
on-board WM9715 touchscreen controller.
 
The changes and additions to the Linux kernel for CM-iGLX are available
 
as patch generated versus
 
link:http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2[Linux
 
kernel 2.6.20].
 
 
 
The following example demonstrates how to compile Linux kernel for
 
CM-iGLX:
 
 
 
-----------------------------------------------------------------------
 
# mkdir /path/to/cm-iglx/kernel/
 
# cd /path/to/cm-iglx/kernel/
 
# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2
 
# tar xjf linux-2.6.20.tar.bz2
 
# cd linux-2.6.20
 
# patch -p1 < /path/to/compulab/package/linux-2.6.20.patch
 
# cp /path/to/compulab/package/linux-2.6.20.config .config
 
# make menuconfig
 
# make && INSTALL_MOD_PATH=/path/to/target make modules_install
 
-----------------------------------------------------------------------
 
 
 
Note, that after the compilation is finished the drivers compiled as
 
loadable kernel modules will be stored in
 
`/path/to/target/lib/modules/<kernel version>/` directory. This
 
directory should be transfered to the CM-iGLX root file system.
 
 
 
Additional information about kernel build process can be found in
 
README file in the kernel source tree.
 
 
 
Graphics support
 
05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)~
 
 
 
Kernel
 
^^^^^^
 
We added driver GeodeLX frame buffer device. It's implementation
 
resides in  `drivers/video/geode` and `lib/cimmaron` in the kernel
 
source tree.
 
 
 
X11
 
^^^
 
X11-specific graphics driver included in CM-iGLX image was complied
 
from source files located at `drivers/xf86-video-amd.tar.bz2` in our
 
Linux package.
 
 
 
Custom LCD configuration
 
^^^^^^^^^^^^^^^^^^^^^^^^
 
You can adjust X server to support displays with non-standard resolution.
 
To do so you need to edit /etc/X11/xorg.conf configure file.
 
 
 
There are some fundamental things you need to know before hacking a xorg.conf. These are:
 
Your monitor's horizontal and vertical sync frequency options
 
Your video adapter's driving clock frequencies, or "dot clocks"
 
 
 
The horizontal sync frequency is just the number of times per second the monitor can write a horizontal scan line; it is the single most important statistic about your monitor. The vertical sync frequency is the number of times per second the monitor can traverse its beam vertically.
 
 
 
Sync frequencies are usually listed on the specifications page of your monitor manual. The vertical sync frequency number is typically calibrated in Hz (cycles per second), the horizontal one in KHz (kilocycles per second). The usual ranges are between 50 and 150Hz vertical, and between 31 and 135 KHz horizontal.
 
 
 
If you have a multisync monitor, these frequencies will be given as ranges.
 
For AMD Geode LX800 video adapter's driving clock frequency range is 25.18 to 229.50 MHz.
 
 
 
Now read carefully the "Timing Chart" section in your display documentation.
 
Find the typical values for "active time", "blanking time", "front porch",
 
"sync time", "back porch" both for the horizontal and vertical timings.
 
Your target is to create appropriate "modeline", for example:
 
 
 
---------------------------------------------------------------
 
#Modename clock  horizontal timing    vertical timing
 
"752x564"    40    752 784  944 1088    564 567 569 611
 
---------------------------------------------------------------
 
 
 
The horizontal section consists of four fields, which specify how each horizontal line on the display is to be generated.
 
 
 
The first field of the section (752) contains the number of dots per line which will be illuminated to form the picture - "active time". The second field of the section (784) indicates at which dot the horizontal sync pulse will begin. Difference between second and first fields called "front porch". The third field (944) indicates at which dot the horizontal sync pulse will end. Difference between third and second fields called "sync time". The fourth field (1088) specifies the total horizontal frame length. Difference between fourth and third fields called "back porch".
 
 
 
The vertical section also contains four fields. The first field (564) contains the number of visible lines, which will appear on the display. The second field (567) indicates the line number at which the vertical sync pulse will begin. The third field (569) specifies the line number at which the vertical sync pulse will end. The fourth field contains the total vertical frame length (611).
 
 
 
Note again that all of the horizontal numbers (752, 784, 944, and 1088) are divisible by eight!
 
 
 
Choose the desired refresh rate (for example 60 Hz) to obtain appropriate dot-clock frequency:
 
 
 
.......................................................
 
Dot-clock frequency = 1088*611*60 Hz = 40 MHz ("clock" field in "modeline").
 
.......................................................
 
 
 
Ensure that it in range of supported by CM-iGLX video adapter's frequencies. Ensure that horizontal and vertical sync frequencies are supported by your display.
 
 
 
Now it's time to edit your /etc/X11/xorg.conf.
 
 
 
Find section named "Monitor" and add lines:
 
 
 
------------------------------------------------------
 
UseModes "Custom"
 
HorizSync 30 - 50
 
VertRefresh 65 - 72
 
------------------------------------------------------
 
(Don't forget to specify values of your display!)
 
 
 
Find section named "Screen" and add lines:
 
------------------------------------------------------
 
SubSection "Display"
 
Depth    16
 
Viewport  0 0
 
Modes    "752x564"
 
EndSubSection
 
------------------------------------------------------
 
 
 
Add section named "Modes" with the following content:
 
 
 
------------------------------------------------------
 
Section "Modes"
 
Identifier "Custom"
 
ModeLine  "752x564" 40 752 784 944 1088   564 567 569 611 +hsync +vsync
 
EndSection
 
------------------------------------------------------
 
 
 
Save the file and restart X server.

Kernel
 
^^^^^^
 
 
 
Wolfson WM97xx touchscreen controller
 
+++++++++++++++++++++++++++++++++++++
 
 
 
The kernel driver for WM97xx touchscreen controller can be found in
 
`drivers/input/touchscreen/wm97xx.*`.
 
The driver has several parameters, that can be modified to adopt the
 
driver behaviour to particular touchscreens and application needs:
 
 
 
* `*dejitter_history*` - touchscreen dejitter filter history length
 
* `*enable_btn*` - enable/disbale BUTTON_* events.
 
* `*abs_x*` - touchscreen absolute X min, max, fuzz
 
* `*abs_y*` - touchscreen absolute Y min, max, fuzz
 
* `*rpu*` - set internal pull up resitor for pen detect
 
* `*pil*` - set current used for pressure measurement
 
* `*pressure*` - set threshold for pressure measurement
 
* `*delay*` - set adc sample delay
 
 
 
NXP UCB1400 touchscreen controller
 
++++++++++++++++++++++++++++++++++
 
 
 
There are older CM-iGLX board assembled with UCB1400 touchscreen
 
controller. We provide two drivers for this controller - `ucb1400_ts`,
 
the driver present in the kernel mainline, and also older version of
 
that driver, `ucb1x00_ts`, being in use for a while on ARM-based
 
platforms. By default the `ucb1400_ts` driver is loaded automatically
 
at the system startup (see `/etc/modules.autoload.d/kernel-2.6`)
 
 
 
X11
 
^^^
 
X11-specific touchscreen driver included in CM-iGLX image was complied
 
from source files located at `drivers/xf86-input-evtouch.tar.bz2` in our
 
Linux package.
 
 
 
Calibration utility
 
^^^^^^^^^^^^^^^^^^^
 
The touchscreen calibration utility `ev_calibrate` is a part of the
 
image.  Please consult `/usr/share/mnt/xf86-input-evtouch/README` for
 
touchscreen calibration instructions.

Software management and development
 
-----------------------------------
 
The software packages for CM-iGLX were prepared in a way very similar
 
to described below. If you setup your host workstation in the way we
 
describe here, you'll be able to add/remove Gentoo packages for your
 
target system using Portage environment, develop and test your
 
application of the host workstation, and finally choose what packages,
 
and files you want to deploy to your production target.
 
 
 
Host side workstation setup
 
---------------------------
 
Setup a Linux PC workstation. Any modern Linux distribution (such as
 
Fedora Core, SuSe, Ubuntu) will work. We used Gentoo Linux on our
 
host, but it's not mandatory. We recommend installing ssh, and nfs
 
servers, so you can access the same files from both host workstation
 
and CM-iGLX.
 
 
 
Development file system setup

Download
 
link:http://distfiles.gentoo.org/releases/x86/2006.1/stages/stage3-i686-2006.1.tar.bz2[Gentoo
 
stage3] and link:http://distfiles.gentoo.org/releases/snapshots/2006.1/portage-2006.1.tar.bz2[Portage tree] from prefered Gentoo mirrors.
 
Download CompuLab
 
link:http://www.compulab.co.il/iglx/download/iglx-linux.zip[Linux
 
package] to your Linux workstation and create a directory that you will
 
be using for CM-iGLX development, say `/mnt/gentoo`:
 
 
 
-------------------------------------------------------------
 
# mkdir /mnt/gentoo
 
# wget http://distfiles.gentoo.org/releases/x86/2006.1/stages/stage3-i686-2006.1.tar.bz2
 
# tar xjf stage3-i686-2006.1.tar.bz2 -C /mnt/gentoo
 
# cd /path/to/compulab/package
 
# wget http://www.compulab.co.il/iglx/download/iglx-linux.zip
 
# unzip iglx-linux.zip
 
# tar xjf portage.tar.bz2 -C /mnt/gentoo/usr
 
# cp /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
 
-------------------------------------------------------------
 
 
 
Now you have basic Gentoo system on your host workstation that can be
 
used for software development and management for CM-iGLX. To use this
 
system you just need to `chroot` into the Gentoo environment:
 
 
 
-------------------------------------------------------------
 
# mount -t proc proc /mnt/gentoo/proc
 
# mount -o bind /dev/ /mnt/gentoo/dev
 
# mount -t sysfs sys /mnt/gentoo/sys
 
# chroot /mnt/gentoo /bin/bash
 
# env-update
 
-------------------------------------------------------------
 
 
 
Target file system extraction
 
05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)[[User:Mike|Mike]] 05:05, 10 March 2008 (EDT)
 
The CM-iGLX Gentoo image contains partition table, `/boot` and `/`
 
partitions. Each of the partitions can be loop-mounted using
 
`image_mount.sh` script, and it's contents can be copied to a
 
directory on your host workstation.
 
 
 
-------------------------------------------------------------
 
# cd /path/to/compulab/package
 
# gunzip gentoo.img
 
# mkdir gentoo.img.mnt
 
# ./scripts/image_mount.sh gentoo.img root gentoo.img.mnt
 
# mkdir /opt/glx
 
# cp -a /path/to/compulab/gentoo.img.mnt /mnt/gentoo/opt/glx
 
-------------------------------------------------------------
 
 
 
At this point your host workstation has two Gentoo systems, one is
 
fully functional, that can be used for development and testing, and
 
the other one is exact copy of Gentoo Linux image on CM-iGLX.
 
The directory tree on your host will resemble the following figure:
 
 
 
-------------------------------------------------------------
 
.

|-- boot
 
|-- dev
 
|-- etc
 
|-- home

NFS setup
 
05:05, 10 March 2008 (EDT)[[User:Mike|Mike]] 05:05, 10 March 2008 (EDT)
 
CM-iGLX can use networked file system as its root filing system. It
 
allows faster turn-around for software updates, development and
 
testing. Using the same files on both host and target computers,
 
without need to reflash entire file system to the target greatly
 
simplifies development for embedded systems. That's why we recommend
 
setting up NFS server on your host workstation, and using
 
NFS-exported files as root file system on CM-iGLX.
 
 
 
1. Set up the NFS server on your host Linux system. If you are using
 
Gentoo Linux
 
+
 
-----------------------------
 
# emerge nfs-utils
 
# rc-update add nfs default
 
-----------------------------
 
+
 
If you're using other Linux distribution, refer to its manuals to find
 
out how to setup NFS server.
 
 
 
2. Export target file systems - add the following lines to your `/etc/exports`:
 
+
 
-------------------------------------------------------------
 
/mnt/gentoo/ 192.168.1.0/255.255.255.0(sync,no_root_squash,rw)
 
/mnt/gentoo/opt/glx 192.168.1.0/255.255.255.0(sync,no_root_squash,rw)
 
-------------------------------------------------------------
 
+
 
 
 
3. Start the NFS server
 
+
 
-------------------------------------------------------------
 
# /etc/init.d/nfs start
 
-------------------------------------------------------------
 
 
 
To setup CM-iGLX to boot with NFS-root you need to add the following
 
entry into `/boot/grub/grub.conf` on the CM-iGLX USB NAND flash:
 
 
 
-------------------------------------------------------------
 
title Gentoo Linux (NFS root)
 
kernel vmlinuz-2.6.20-cm-iglx root=/dev/nfs nfsroot=<server_ip>:/mnt/gentoo ip=::::cm-iglx:eth1:
 
boot
 
-------------------------------------------------------------
 
 
 
The `/boot/grub/grub.conf` file can be modified either on running
 
Linux system on the CM-iGLX.
 
 
 
More information about using NFS root can be found in Linux kernel
 
documentation in `Documentation/nfsroot.txt` in the kernel source tree.

Package management
 
------------------
 
 
 
Development Gentoo system
 
05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)
 
You can use
 
link:http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1[Gentoo
 
Portage] installer to add, remove and modify packages on both
 
development and target file systems. After you performed all the steps
 
describe in the previous section, you can `*chroot*` to the
 
development Gentoo system, and use `emerge` utility to manage software
 
packages on it.
 
 
 
Here's the contents of `make.conf` we used to create the CM-iGLX
 
image:
 
-------------------------------------------------------------
 
CFLAGS="-Os -mtune=k6-2 -pipe -fomit-frame-pointer"
 
CHOST="i686-pc-linux-gnu"
 
CXXFLAGS="${CFLAGS}"
 
FEATURES="noman nodoc noinfo buildpkg"
 
USE="-opengl bitmap-fonts truetype-fonts type1-fonts X alsa"
 
-------------------------------------------------------------
 
 
 
You can copy these settings to the `/mnt/gentoo/etc/make.conf` file and
 
add or modify them, esspecially USE flags, to create packages that
 
suit most your application needs.
 
 
 
 
 
Target System
 
05:05, 10 March 2008 (EDT)05:05, 10 March 2008 (EDT)[[User:Mike|Mike]]
 
 
 
The target system extracted from `gentoo.img` needs some additional
 
information to allow proper usage of portage. Due to size limitations,
 
the packages database of the target file system, is shipped in a
 
separate archive: `var-db-pkg.tar.bz2`. To make use of it you need to
 
extract it into appropriate place:
 
 
 
-------------------------------------------------------------
 
# tar xjf /path/to/compulab/package/package_management/var-db-pkd.tar.bz2 -C /mnt/gentoo/opt/glx/var/
 
-------------------------------------------------------------
 
 
 
Next, after `*chroot*`\`ing into the development Gentoo system you can `emerge` packages into the target file system:
 
 
 
-------------------------------------------------------------
 
# ROOT=/opt/glx emerge <package spec>
 
-------------------------------------------------------------
 
 
 
 
 
NAND flash image creation and deployment
 
----------------------------------------
 
Last step in embedded software development is deployment of the file
 
system to the device. There several ways to do it.
 
 
 
First of all, you can loop-mount the `gentoo.img` file, copy the files
 
from updated target file system back to the image, and use the way
 
described in link:Installation_and_Features.pdf["Installation & Features"].
 
 
 
Another way is to use `/mnt/gentoo` as NFS-root, and than mount the
 
NAND flash, and copy the files from `/mnt/gentoo/opt/glx` directly to
 
the NAND flash.
 
 
 
Yet another way is to create bootable USB-stick, copy the target files
 
to it and than transfer entire contents of the USB-stick onto the
 
CM-iGLX on-board NAND flash.
 
 
 
Known problems and limitations
 
------------------------------
 
 
 
* Some USB mass storage devices cause incorrect mount of root file
 
  system. Instead of using on-board USB NAND flash as root, Linux
 
  kernel will try to mount an external USB storage device.
