Barebox

2011-10-28T09:08:06Z

Rschwebel: some cleanup

The Barebox bootloader was started in 2007 as an attempt to work around the limitations that U-Boot shows through its age. Originally dubbed U-Boot v2, it now has a different name because its design goals are different and it has it's own community in the meantime.

Barebox now supports arm, powerpc, mips, nios2, blackfin, x86 and a Linux userspace port called "sandbox".

[http://www.barebox.org Barebox]

[[:File:Hauer-U_BootV2.pdf|U-Boot-v2 Presentation from CELF Embedded Linux Conference Europe Grenoble, 2009-10-16]] (pdf)

[[:File:ELCE-2010-Barebox-Booting-Linux-Fast-and-Fancy.pdf|Booting Linux Fast & Fancy]] (pdf)

= Sandbox =

One of the great thinks with barebox is the sandbox.

Basically you can develop and debug generic feature on your host:

1) compile it

for other arch than x86 or ppc you need to use the next branch or the mainline

As I just recently fix the support for all host

ARCH=sandbox make sandbox_defconfig

ARCH=sandbox make

now just start it

= Menu =

It's on ather great feature

Add Menu Framework

Introduce a menu framework that allow us to create list menu to simplify
barebox and make it more user-frendly

This kind of menu is very usefull when you do not have a keyboard or a
serial console attached to your board to allow you to interract with
barebox

For the develloper part,
The framework introduce two API

1) C
that allow you to create menu, submenu, entry and complex menu action

2) Command
that allow you as the C API to create menu, submenu, entry and complex
menu action but this time the actions will be store in a function and
then be evaluated and excecuted at runtime.

barebox:/ help menu
Usage: menu [OPTION]...

Ktest

2011-10-28T08:38:41Z

Rschwebel: Steven's tree is not available right now, so use Linus'

[http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=tree;f=tools/testing/ktest;h=8a0059676b3d8aa368b1fc239462b4d778481a09;hb=HEAD ktest.pl] is a
perl script [http://lxr.linux.no/#linux/tools/testing/ktest/ in the kernel source tree] that reads a simple config file to perform kernel testing. If you have a target machine that can be remotely rebooted and have its console viewed
by a remote server, then you can use ktest.pl to perform automated tests. The tests that you can perform are:

* git bisecting
* config bisecting
* randconfig
* any .config boot/test
* patch checking

The tests allow you to perform build, boot or tests on each kernel that is tested. Although ktest is written in perl, you do not
need to know anything about perl to use ktest. ktest.pl takes a single config file for its input and will run the tests according
to that config file. ktest.pl has been included in the mainline Linux kernel under the directory tools/testing/ktest. There
exists a [http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob_plain;f=tools/testing/ktest/sample.conf;hb=HEAD sample config] that covers all the configurations that can be specified to use ktest.

= Sub Types of tests =

Each test that can be executed has three types of testing: build, boot and test. Some of these sub types
may perform differently with different test types.

== Build testing ==

Build testing will just build the kernel. This does not requier having another machine to do remote testing, although
some of the options may need to tell ktest that it can reboot this non-existent machine but if all you do is build the
kernel, it will never get to the point that it will require rebooting it.

== Boot testing ==

If you can supply ktest.pl with a way to remotely boot the target, as well as read its console via stdio, then
you can perform boot testing. This does currently require ssh (actually scp) connectivity to the target (not necessarily
with the kernel that was built) to be able to copy the boot image to the kernel (if one is needed) and perhaps the
modules that that kernel uses, again if one is needed.

After a successful build, ktest will copy the necessary files over to the target and reboot the target to that
kernel. It will watch the console for a specified string (default "login:") that will tell ktest.pl that the
boot succeeded. There's configurable timeouts that ktest.pl uses to determine if the boot locked up or not.

== Test testing ==

The config option "TEST" may point to any bash string (which could also call a script) that will be executed after
the build and boot has succeeded. The TEST bash line could ssh to the target to execute some test (perhaps even LTP).
The one requirement is that on success the bash command returns 0 to let ktest.pl know if the test succeeded or not.

= Test types =

== Simple type ==

The simple test type usually just takes a standard config and builds, boots and tests depending on what the sub type
states.

== Git Bisect type ==

The git bisect type will perform a git bisect on the source tree (which ktest assumes is a git repository). Depending on
the test type, it will test build, boot or some other test. If a boot or test fails on build (or test fails on boot)
it will execute git bisect skip as ktest.pl assumes the current git commit has corrupted the environment, and the git
bisect skip should hopefully take the git repo to something that can successfully get past the problem areas.

The bisect test type also supports checking the initial good and bad commits before it wastes time doing a bisect
in those cases you are not sure the good and bad points or perhaps the test you set up is correct. When
BISECT_CHECK is set, the good commit is checked out and ktest.pl makes sure that the test succeeds, and then the bad commit is checked
out to make sure it fails the test.

In those strange cases that something just started working when it was broken before, you can enable
BISECT_REVERSE, where a ktest.pl will execute git bisect good on failure, and git bisect bad when the test
succeeds. This will find that commit that fixed the bug.

== Patch check type ==

For those maintainers that take patches from others, or simply want to run that last set of patches that
have been committed into git through some verification tests before sending the results upstream, the patch
check can help. It will checkout the git repo of one commit and incrementally checkout each commit leading up to
a final commit to check and for each commit it will execute the PATCHCHECK_TYPE subtype of test. This test
modifies what the build does (for all test subtypes). If warning appears in a file that the commit touches,
then it will fail the build. As there is no good reason that new code should add new warnings to the kernel.

== randconfig type ==

The randconfig test type will execute randconfig to create the config file for the build. You can also specify
a MIN_CONFIG that will hold the default configs that should be set for the config (both enabled and disabled
configs, so make sure you remove anything that you do not want to force in that file). This is a test that is
useful to use the ITERATE option of ktest.pl to iterate a single test type several times.

== config bisect ==

On those off occasions that you find that you have two configs for the same version of the kernel, yet
one works and the other does not and you have no idea which config is the problem config. ktest.pl supplies
a config bisect that will try various configs doing a semi bisect to find the culprit. It is a semi config
as the config dependencies prevents a true bisect to be done.

== make_min_config ==

When a user of your code has a bug it is common to ask the user for their config file. The problem is that
their config file may not boot on your machine. The solution is to add a minimum configuration that you
know is needed to boot your box. But if your minimum configuration is not the true minimum, it is likely
that one of your configurations might override the config that causes the bug. Having a true minimum
config limits this collision, and if the minimum still hides the bug, the bug is a machine specific bug
and not a configuration issue.

Using make_min_config, you can bring down a config that was made by localmodconfig from 1200 configurations
to 148 configurations. Even better, ktest.pl will keep track of the individiual configurations that were needed
otherwise the box did not boot. That is, just the ones that failed to boot and not set because another config
was set. This config ended up being 13 configs, and just adding these configs to an allnoconfig allowed it to boot.

Freescale IMX53QSB

2011-10-26T21:28:13Z

Rschwebel: Fix up spelling, clarify a few things.

== Topics ==
= Hardware=

The i.MX53 Quick Start Board (aka LOCO) is a 1 GHz ARM Cortex-A8 embedded computer on a 3-inch by 3-inch board.

The loco boots from SD Card with the boot loader at the first sector of it.

You can use Barebox on it:

http://git.pengutronix.de/?p=barebox.git;a=summary

= Barebox =

Barebox uses the same build (Kbuild) and configuration (Kconfig) tools as the Linux kernel.

1) First you need to clone the tree

git clone git://git.pengutronix.de/git/barebox.git

Most probably you want to use a released Barebox version, by running 'git checkout <version>'. Check which versions are available with 'git tag -l' and use the latest one.

2) Then you need to configure it:

make freescale_mx53_loco_defconfig

3) Compile it

make

4) Now you need to generate your SD Card:

Plug the SD Card into your laptop and copy barebox.bin to it:

dd if=barebox.bin of=/dev/sdb bs=512
sync

5) plug the SD card into the board and boot it (press the boot button)

Now that you have flash, you will see Barebox booting and trying to start the kernel from the SD card.

barebox@Freescale i.MX53 LOCO:/

= Kernel =

You can use the mainline kernel, but take into account that not all IP cores available in the MX53 are already supported there. It is also possible to use Freescale's kernel, which can be found here:

http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git;a=summary

1) First you need to clone the tree:

a) Mainline

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

Note that, like with Barebox, if you aim for stability, you should take a released kernel revision instead of some random version from git.

b) Freescale

git clone http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git

git checkout -b work imx_2.6.38_11.09.01

or

To speed up the clone, first clone the linus tree, then fetch freescale as this

or use any already cloned kernel

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

git remote add freescale http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git

git fetch freescale

git checkout -b work freescale/imx_2.6.38_11.09.01

2) Then you need to configure the kernel:

make imx5_defconfig

3) Compile it

make

If you have a machine with more than one core, add -j <number-of-parallel-builds>.

4) now you need to generate your SD Card:

Plug the sd card on your laptop and copy barebox.bin on it

dd if=arch/arm/boot/uImage of=/dev/sdb bs=512 seek=768
sync

5) Plug the SD card into the board and boot it (press the boot button)

Now that you have flashed everything, you will see barebox booting and trying to start the kernel from the SD card.

CAN Bus

2010-01-04T21:04:32Z

Rschwebel: updated CAN infos

=== Overview ===

The CAN bus is an ISO standard bus for vehicles. It manages the Chassis Electrical System Control
and is responsible for critical activities like engine electrical, and skid control. This system is also used
to provide vehicle diagnostic information for maintenance. A multi-star configuration seems typical of
this bus with a primary bus line that branches into sub bus lines at its extremities then attaches to
multiple device nodes. Differential voltage is applied over twisted pair at 1.5 to 2.5V and 2.5 to 3.5V
for noise resistant signaling. Communication occurs at 500 kbps with 1-8 Bytes of data inside of each
transmitted packet.

(Jeremiah J. Flerchinger [[media:avc-lan.pdf|Source]])

=== CAN Support in Linux ===

Talk:CAN Bus

2010-01-04T20:54:22Z

Rschwebel: start discussion

This article contains bugs (i.e. the bitrate is *not* 500 kBit/s, bit timing is much more complicated with CAN; packets can also have 0 byte payload).

Wouldn't it be much better to just refer to http://en.wikipedia.org/wiki/CAN_bus here?

Bootloader

2010-01-04T20:33:27Z

Rschwebel: U-Boot-v2 was recently renamed to Barebox

Briefly, a bootloader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to the operating system kernel software (such as the Hurd or the Linux). The kernel, in turn, initializes the rest of the operating system (e.g. GNU).

== Introduction ==

Besides the Linux kernel, one of the advantage of embedded Linux is the ability to leverage hundreds if not thousands of existing free and open source packages to easily and quickly add new features to devices. These packages range from graphical libraries, multimedia libraries, network libraries, cryptographic libraries, network servers, infrastructure software and more. However, integrating all these components together requires a relatively deep knowledge of the components. Hence, embedded-specific distributions and build systems have been created to ease this process.

Toolchains

2009-03-05T13:42:17Z

Rschwebel:

A [http://en.wikipedia.org/wiki/Toolchain toolchain] is a set of distinct software development tools that are linked (or chained) together by specific stages such as GCC, binutils and glibc (a portion of the [http://en.wikipedia.org/wiki/GNU_Toolchain GNU Toolchain]). Optionally, a toolchain may contain other tools such as a [http://en.wikipedia.org/wiki/Debugger Debugger] or a [http://en.wikipedia.org/wiki/Compiler Compiler] for a specific programming language, such as ,[http://en.wikipedia.org/wiki/C%2B%2B C++]. Quite often, the toolchain used for embedded development is a cross toolchain, or more commonly known as a [http://en.wikipedia.org/wiki/Cross_compiler cross compiler]. All the programs (like GCC) run on a host system of a specific architecture (such as x86) but produce binary code (executables) to run on a different architecture (e.g. ARM). This is called cross compilation and is the typical way of building embedded software. It is possible to compile natively, running gcc on your target. Before searching for a prebuilt toolchain or building your own, it's worth checking to see if one is included with your target hardware's [http://en.wikipedia.org/wiki/Board_support_package Board Support Package (BSP)] if you have one.

== Note about C libraries ==
Realistically, there are two options for the C Library: [http://en.wikipedia.org/wiki/Uclibc uClibc] & [http://en.wikipedia.org/wiki/Glibc glibc]. GLibc is what your PC is probably using. It's a bit of a brute, very powerful but a bit bloated. If flash space and memory footprint is an issue, using uClibc is likely to be the better option. However, the space advantages gained using uClibc are becoming less important as the price of memory & flash continues to drop. There are a few "gotcha"s when using uClibc. At time of writing(uClibc 0.9.28), locales are a bit ropey and the new Application Binary Interface (ABI) for ARM architectures (EABI) introduced with GCC 4.1.1 requires patches to be applied. This situation is likely to get better quickly as uClibc is under heavy development.

== Available Toolchains ==
Creating a cross development toolchain from sources can be a real pain. There are version dependency issues, patches required to make something work etc. etc. Check out the [http://kegel.com/crosstool/crosstool-0.43/buildlogs/ build matrix] for crosstool and look at all the red "failed" entries. Fortunately, there are several groups of people who have done all the hard work for you, producing scripts to create a toolchain or releases of binary toolchains.

=== DENX ELDK ===
The DENX Embedded Linux Development Kit (ELDK) provides a complete and powerful software development environment for embedded and real-time systems. It is available for ARM, PowerPC and MIPS processors and consists of:

* Cross Development Tools (Compiler, Assembler, Linker etc.) to develop software for the target system.
* Native Tools (Shell, commands and libraries) which provide a standard Linux development environment that runs on the target system.
* Firmware (U-Boot) that can be easily ported to new boards and processors.
* Linux kernel including the complete source-code with all device drivers, board-support functions etc.
* Xenomai - RTOS Emulation framework for systems requiring hard real-time responses.
* SELF (Simple Embedded Linux Framework) as fundament to build your embedded systems on.

All components of the ELDK are available for free with complete source code under GPL and other Free Software Licenses. Also, detailed instructions to rebuild all the tools and packages from scratch are included.

The ELDK can be downloaded for free from several mirror sites or ordered on CD-ROM for a nominal charge (99 Euro). To order the CD please contact office@denx.de

Detailed information about the ELDK is available [http://www.denx.de/wiki/DULG/ELDK here].

=== Buildroot ===
Buildroot is a complete build system based on the Linux Kernel configuration system and supports a wide range of target architectures. It generates root file system images ready to be written to flash. In addition to having a huge number of packages which can be compiled into the image, it also generates a cross toolchain to build those packages from source. Even if you don't want to use buildroot for your root filesystem, it is a useful tool for generating a toolchain. It should be noted however that it only supports uClibc. If you want to use glibc, you'll need something else. Link: [http://buildroot.uclibc.org/ Buildroot homepage]

=== Scratchbox ===
Scratchbox provides toolchains for ARM and x86 target architectures (with PowerPC, MIPS and CRIS in experimental stages). Both uClibc & glibc are supported. Scratchbox simplifies cross compiling software which is built using GNU autotools - Code tests performed by configure are run in an emulator or even on the actual target. The toolchains scratchbox ships with are based on gcc 3.3 and as such are quite old, but stable and well tested. It should be pointed out that scripts to build custom toolchains are also provided with scratchbox allowing more recent gcc versions to be used. Link: [http://www.scratchbox.org/ Scratchbox]

=== Crossdev (Gentoo) ===
Crossdev is specific to developers using Gentoo for their development PCs. It is a script which generates a cross toolchain using the portage build scripts for gcc etc. There are numerous architectures which are supported and both uClibc and glibc toolchains can be built. Link: [http://gentoo-wiki.com/HOWTO_Cross_Compile Gentoo Cross-Compile HOWTO]

=== Crosstool ===
Crosstool is a script which downloads source tar-balls and builds simple gcc/glibc cross toolchains. There is a build matrix which shows which versions of gcc/glibc work together with various architectures ([http://kegel.com/crosstool/crosstool-0.43/buildlogs/ link]). The inclusion of this matrix makes it easy to select which versions of gcc/glibc should be used to generate a toolchain for a particular architecture. Link: [http://kegel.com/crosstool/ Crosstool]

=== Crosstool-NG ===
Crosstool-NG is a fork of crosstool, targeted at easier configuration, re-factored code, and a learning base on how toolchains are built, with support for both uClibc and glibc, for debug tools (gdb, strace, dmalloc...), and a wide range of versions for each tools. Different target architectures are supported as well. Link: [http://ymorin.is-a-geek.org/dokuwiki/projects/crosstool crosstool-NG]

=== CodeSourcery ===
[http://www.codesourcery.com/ CodeSourcery] develops [http://www.codesourcery.com/gnu_toolchains/sgpp/ Sourcery G++], an [http://en.wikipedia.org/wiki/Eclipse_IDE Eclipse] based [http://en.wikipedia.org/wiki/Integrated_development_environment Integrated Development Environment (IDE)] that incorporates the [http://en.wikipedia.org/wiki/GNU_toolchain GNU Toolchain] (gcc, gdb, etc.) for cross development for numerous target architectures. [http://www.codesourcery.com/ CodeSourcery] provides a "lite" version for [http://www.codesourcery.com/gnu_toolchains/arm ARM], [http://www.codesourcery.com/gnu_toolchains/coldfire Coldfire], [http://www.codesourcery.com/gnu_toolchains/mips MIPS] and [http://www.codesourcery.com/gnu_toolchains/power Power] architectures. The toolchains are always very up to date. [http://www.codesourcery.com/ CodeSourcery] contributes enhancements it makes to the [http://en.wikipedia.org/wiki/GNU_toolchain GNU Toolchain] upstream continually, making it the single largest (by patch count) corporate contributor.

=== Crossdev/tsrpm (Timesys) ===
Crossdev is a project sponsored by Timesys, completely unrelated to the Gentoo cross toolchain generation system. The projects main focus is on a tool called tsrpm which is used to build cross development toolchains and generate cross-compiled software packages. Currently only x86 and select PowerPC architectures are supported. Link: [https://crossdev.timesys.com/ Crossdev]

=== Fedora ARM ===
Fedora ARM is a try to port Fedora to ARM.
It provides some tools as an ARM toolchain packaged in RPM format.
Link: [http://fedoraproject.org/wiki/Architectures/ARM Fedora ARM]

=== Embedded Debian cross-tools packages ===
For Debian users, the toolchains problem is fairly reliably solved.

For a debian-based box just install pre-built cross toolchains from emdebian. Instructions are given here:
http://www.emdebian.org/tools/crosstools.html

Supported build architectures are: i386, amd64, (and powerpc, ish)
Targets insclude nearly all debian-supported architectures
Compilers are gcc3.3, 3.4, 4.1, 4.2, 4.3. Lenny and sid are supported although the tools are inevitably slightly behind Debian proper.

http://www.emdebian.org/toolchains/search.php?section=devel gives a (long) listing of available packages.

emdebian-tools also provides the debian equivalent of crosstool
('emchain' to build your own version of current toolchain,
should a suitable pre-built one not exist.

=== OSELAS.Toolchain() ===
The OSELAS.Toolchain() project aims at supplying a complete build system for recent GNU toolchains. It uses the PTXdist build system, a userland build system based on Kconfig. The current version 1.99.3.1 of OSELAS.Toolchain() contains support for arm, x86, avr, mips and PowerPC. In addition, there are toolchains for bare metal platforms like Cortex-M3 and AVR-8-Bit.

=== Bitbake ===
Bitbake is the tool used by [http://wiki.openembedded.net/index.php/Main_Page OpenEmbedded]. There is a bitbake manual at http://bitbake.berlios.de/manual/, but the best way to get started is probably by just building an existing distribution that uses openembedded (e.g. Ångström, see http://www.angstrom-distribution.org/building-%C3%A5ngstr%C3%B6m for details).
