Repository:

• git://support.criticallink.com/home/git/linux-socfpga.git
• https://support.criticallink.com/git/linux-socfpga.git

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
   

   source /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
