Linux Kernel

Repository: Kernel Branch:
  • socfpga-4.9.78-ltsi
Kernel defconfig:
  • mitysom_a10s_defconfig
Device Tree:
  • mitysom_a10s_devkit.dts

The following steps will recreate the kernel and device tree for the MitySOM-A10S development kit. This will use the yocto SDK that is provided on the files section. Please note that the kernel and dtb will normally be built through the yocto build but the steps here are provided for development.

  1. Source the yocto SDK
    . /opt/poky/2.4.3/environment-setup-cortexa9hf-neon-poky-linux-gnueabi
    
  2. Checkout the kernel source
    git clone https://support.criticallink.com/git/linux-socfpga.git -b socfpga-4.9.78-ltsi
    
  3. Change into the kernel source
    cd linux-socfpga
    
  4. Set the defconfig
    make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- -j8 mitysom_a10s_defconfig
    
  5. Build the kernel
    make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- -j8 zImage
    
  6. Build the device tree
    make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- -j8 dtbs
