VAR-SOM-MX6 - Yocto fsl-3.14.38_6qp Fido R2 u-boot 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 U-Boot out of Yocto tree
Note:
This is a single u-boot image that supports all VAR-SOM-MX6 SOMs.
This is a single u-boot image that supports all VAR-SOM-MX6 SOMs.
Obtain sources:
$ cd ~/var-som-mx6-yocto-fido $ git clone https://github.com/varigit/uboot-imx $ cd uboot-imx/
- follow above procedure for installing the toolchain
Build u-boot:
$ source /opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
clean tree:$ make mrproper
Choose build for SD-Card or NAND Flash: $ make mx6var_som_sd_config or $ make mx6var_som_nand_config
Build U-BOOT: $ make
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.
