Building the Intel SoC-FPGA kernel and devicetrees from source

The script method

We provide a script that does automates the build for SoC-FPGA using the Linaro toolchain.

The script takes up to 3 parameters, but if left blank, it uses defaults:

  1. <local_kernel_dir> - default is linux-adi if left blank ; use this, if you want to use an already cloned kernel repo
  2. <devicetree_file> - which device tree should be exported/copied from the build [argument is optional]
  3. <path_to_other_toolchain> - in case you have your own preferred toolchain [other than Linaro's or Intel's] you can use override it with this 3rd param

The script will:

  1. clone the ADI kernel tree
  2. download the Linaro GCC toolchain [if no other is specified]
  3. build the ADI kernel tree
  4. export/copy the Image file and device tree file out of the kernel build folder

Running the script in one line [with defaults]

wget https://raw.githubusercontent.com/analogdevicesinc/wiki-scripts/master/linux/build_socfpga_kernel_image.sh && chmod +x build_socfpga_kernel_image.sh && ./build_socfpga_kernel_image.sh

Checkout the Release branch

If not otherwise required always use the latest release!
Release names and Branches
altera_4.0

dave@hal9000:~/github-linux-build/linux$ git checkout origin/altera_4.14 -b altera_4.14
Branch altera_4.14 set up to track remote branch altera_4.14 from origin.
Switched to a new branch '2015_R2'

Setup cross compile environment variables

There are a few toolchains that can be used.

Other toolchains/compilers for ARM may work as well, but the ones described here have been tested and found to work.

Using the Linaro toolchain

Alternatively, the Linaro toolchain/compiler can be used to compile to kernel. Linaro compilers (that work with Intel SoC-FPGA) can be downloaded from: https://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linux-gnueabi/

Example: 

wget https://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linux-gnueabi/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabi.tar.xz
tar -xvf gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabi.tar.xz
export ARCH=arm
export CROSS_COMPILE=$(pwd)/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-
