Variscite Yocto Daisy release 1 Alpha for Freescale i.MX6.
Installing required packages
Follow the link below and install all required packages on your machine.
www.yoctoproject.org/docs/latest/yocto-project-qs/yocto-project-qs.html
For example, if your building machine is an Ubuntu machine:
sudo apt-get install gawk wget git-core diffstat unzip texinfo build-essential chrpath libsdl1.2-dev xterm lzop
Variscite Yocto build was tested with Ubuntu 12.04 LTS only!
Download Yocto Daisy for i.MX6 with Variscite VAR-SOM-MX6 support
Use "repo" to fetch Yocto and apply Variscite's patches for the BSP support:
- Install the `repo` utility:
$ mkdir ~/bin (this step may not be needed if the bin folder already exists) $ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo $ chmod a+x ~/bin/repo Add the following line to the .bashrc file to ensure that the ~/bin folder is in your PATH variable $ export PATH=~/bin:$PATH
NOTE:
Reference repo is available on FTP.
Reference repo is available on FTP.
- Clone Yocto Daisy from Freescale's git:
$ cd ~ $ mkdir var-som-mx6-daisy-v6 $ cd var-som-mx6-daisy-v6 $ git config --global user.name "Your Name" $ git config --global user.email "Your Email" $ repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.10.31-1.1.0_beta $ repo sync
- Download ftp.variscite.com/VAR-SOM-MX6/Software/Linux/Yocto/Release5/var_yocto_v6a1.tar.bz2
- Extract tarball:
$ cd ~/var-som-mx6-daisy-v6 $ tar xvf ~/Downloads/var_yocto_v6a1.tar.bz2 $ variscite/install
Comment:
This method will preserve the git repositories. It will enable you to track Variscite's changes, and your own.

Setup and Customize your Yocto build
Setup the environment and use build_var folder
$ . ./setup-environment build_var
Comment:
If you close your terminal and wish to build Yocto again, you should change directory to ~/var-som-mx6-daisy-v6 and run the above command again. build_var is your build directory and all bitbake commands should run from it

local.conf customizations
Edit you local.conf file:
$ gedit conf/local.conf
Change parallel build and download directory:
Set the build parameters to fully utilize your host machine's resources
BB_NUMBER_THREADS = '4'
PARALLEL_MAKE = '-j 6'
BB_NUMBER_THREADS should be your host machine's number of threads minus 2 or same. PARALLEL_MAKE should be the number of threads your host machine has plus two.
Change packages download directory: By defualt the path is set to "/opt/yocto_dl". Change ownership settings:
$ sudo mkdir /opt/yocto_dl $ sudo chown <uname>.<uname> /opt/yocto_dl
Build your image
$ bitbake fsl-image-qt5
Other image build options:
The resulted images are locaated in tmp/deploy/images/varsomimx6.
Looking at tmp/deploy/images/varsomimx6 you will find 6 main files that are linked to the actual file

Under development. Coming soon.
Next steps
In sections 1-6 we explained how to build Yocto for VAR-SOM-MX6. We explained the results for nand (UBI) and for sd-card.
At this point you should have a bootable sd-card with UBI images on it. You should be able to boot from the sd-card using the boot select button and flash the nand.
Next steps:
- Build and deploy the compiler and tools.
- Fetch u-boot and compile it out of Yocto tools.
- Fetch Linux kernel and compile it out of Yocto tools.
Toolchain installation for out of Yocto builds
Build the toolchain by:
$ bitbake meta-ide-support $ bitbake meta-toolchain
The output will be located at tmp/deploy/sdk/. On a 64 bit Ubuntu you will get:
sdk/poky-eglibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.6.1.sh.
Install the tools by running:
$ tmp/deploy/sdk/poky-eglibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.6.1.sh
Reply to all defaults 'y'
The toolchain name depend on your build machine and may change.
Build U-Boot out of Yocto tree
Note:
This is a single u-boot image that supports all VAR-SOM-MX6 SOM's.
This is a single u-boot image that supports all VAR-SOM-MX6 SOM's.
Obtain sources:
$ cd ~/var-som-mx6-daisy-v6 $ git clone git://github.com/varigit/uboot-imx $ cd uboot-imx/ $ git checkout -b imx_v2013.10_beta_var4 remotes/origin/imx_v2013.10_beta_var4
- follow above procedure for installing the toolchain
Build u-boot:
$ export PATH=/opt/poky/1.6.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi:$PATH clean tree: $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- mrproper Choose build for SD-Card or NAND Flash: $ make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- mx6var_som_sd_config or $ make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- mx6var_som_nand_config Build U-BOOT: $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi-
Flash u-boot to the sd-card:
$ sudo dd if=SPL of=/dev/sdxxx bs=1K seek=1; sync $ sudo dd if=u-boot.img of=/dev/sdxxx bs=1K seek=69; sync
In case of UBI copy it to the sd-card:
$ sudo cp SPL /media/rootfs/opt/images $ sudo cp u-boot.img /media/rootfs/opt/images
Eject SD-Card gracefully from host machine
Build Linux out of Yocto tree
Get sources:
$ cd ~/var-som-mx6-daisy-v6/ $ git clone git://github.com/varigit/linux-2.6-imx.git $ cd linux-2.6-imx/ $ git checkout -b imx_3.10.31_1.1.0_beta2_var1 remotes/origin/imx_3.10.31_1.1.0_beta2_var1
Build the Linux kernel:
$ export PATH=/opt/poky/1.6.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi:$PATH $ make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- mrproper $ make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- imx_v7_var_defconfig $ make -j6 LOADADDR=0x10008000 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- uImage $ make -j6 LOADADDR=0x10008000 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- modules Build the device tree for Dualite/Solo $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- imx6dl-var-som.dtb Build the device tree for Quad/Dual $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- imx6q-var-som.dtb
Copy the uImage and device tree to the sd-card boot partition or to the opt/image in order to be flashed to the nand. Copy modules to the sd-card
$ sudo make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- modules_install INSTALL_MOD_PATH=/media/rootfs/
