tjohann/arm926_sdk

This is my sdk for usage with slackware on arm926 devices like aria g25 and arietta (see http://www.acmesystems.it/)

ARM926_SDK

NOTE: This repo is deprecated, i wont do any updates. Because both devices are so different (at least for my usecases) that i split it to two different repositorys (https://github.com/tjohann/arietta_sdk and https://github.com/tjohann/imx233_sdk).

This is my arm926te sdk for usage with x86_64 or armv7hf host to develop for devices like arietta or imx233. For more info follow me on google+ and see sourceforge . Also read ./UPGRADE_HINTS and ./docs/info_arm926_sdk.txt .

Usage

Clone the repo into your home directory:

    git clone https://github.com/tjohann/arm926_sdk.git

After cloning, "source" the env file to set the necessary environment variables. You can either set this to run automatically via a .bashrc entry as outlined below..

    # setup the arm926 environment
    if [ -f ~/arm926_sdk/armel_env ]; then
        . ~/arm926_sdk/armel_env
    fi

.. or do it manually everytime you want to work with the sdk.

    . ./armel_env

Note: the env file also extends the PATH so it may cause errors when building other projects/repositories

Download and installation of the toolchain, kernel and image are done via small scripts in $ARMEL_HOME/bin. To download and install the toolchain, type

    make get_toolchain

Now you should have a working compiler to cross compile for an armv5te target like the Arietta.

Additional Commands

To download the images for the target, type

    make get_image_tarballs

To download the latest non-rt and rt kernel, type

    make get_latest_kernel

Useful make tags

make get_toolchain -> download (and install) toochain from sourceforce
make get_external_repos -> clone additional repos (see ./external/README)
make get_latest_kernel -> download latest supported kernel version as tarball and install it to ./kernel/linux-$ARMEL_KERNEL_VER
                          download latest of RT-PREEMPT supported kernel and latest supported RT-PREEMPT-Patch
make get_image_tarballs -> download minimal image from sourceforce to ./images/
make clean -> clean all dirs and subdirs
