VAR-SOM-MX6 - Yocto fsl-3.14.38_6qp Fido R2 Linux out of tree
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-1.8.sh
Install the tools by running:
$ tmp/deploy/sdk/poky-eglibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.sh
Reply to all defaults 'y'
The toolchain name depend on your build machine and may change.
Build Linux out of Yocto tree
Get sources:
$ cd ~/var-som-mx6-yocto-fido $ git clone https://github.com/varigit/linux-2.6-imx.git $ cd linux-2.6-imx/ $ git checkout -b imx_3.14.38_6qp_ga_var01 remotes/origin/imx_3.14.38_6qp_ga_var01
Build the Linux kernel:
$ export PATH=/opt/poky/1.8/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 all device tree: $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- dtbs Build device tree for a specific device 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 Build the device tree for VAR-SOM-SOLO $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- imx6dl-var-som-solo.dtb Build the device tree for VAR-SOM-SOLO on VAR-SOLOCustomBoard $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- imx6dl-var-som-solo-vsc.dtb Build the device tree for DART-MX6 $ make -j6 ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- imx6q-var-dart.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/ $ cp arch/arm/boot/uImage /media/BOT_varsomi $ cp arch/arm/boot/dts/*var*.dtb /media/BOT_varsomi
Update your Linux out of Yocto tree
$ git fetch origin $ git pull
