1. Download and install the SDK to obtain the cross compiler/toolchain
   SDK
2. Source the toolchain
   

   source /opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
   

3. Download U-Boot from our partners GIT repository:
   

   git clone https://git.isee.biz/arm-boot/u-boot-fslc.git
   cd u-boot-fslc/
   git checkout remotes/origin/isee-imx-patches-2015.04-next -b isee-imx-patches-2015.04-next.local
   

4. Configure U-Boot for MitySOM-iMX6 (IGEP) SMARC iMX6 device.
   • iMX6 Quad or Dual
     

     make CROSS_COMPILE=arm-poky-linux-gnueabi- mx6q_igep0046_defconfig
     

   • iMX6 DualLite
     

     make CROSS_COMPILE=arm-poky-linux-gnueabi- mx6dl_igep0046_defconfig
     

   • iMX6 Solo
     

     make CROSS_COMPILE=arm-poky-linux-gnueabi- mx6s_igep0046_defconfig
     

5. Then build u-boot.imx image file in current directory
   

   make CROSS_COMPILE=arm-poky-linux-gnueabi-
