Build commands
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
make socfpga_defconfig
make zImage
make socfpga_de0_nano.dts
2.Buildroot source code
The Buildroot source includes a prelimary SDL2 patch that theOpenCLdemo needed, perl, and X.
git:https://github.com/altcrauer/buildroot.git
branch: 2015_08_with_sdl2_with_xorg
git web link:https://github.com/altcrauer/opencl_soc_bsp/tree/de0_nano_with_display
Build commands
make altera_soc_defconfig
make
3.OpenCLBSP source / FPGA Project
The includes theOpenCLBSP used for this project. This is basically an FPGA project that is used base for theOpenCLcompilation.
git:https://github.com/altcrauer/opencl_soc_bsp.git
branch: de0_nano_with_display
git web link:https://github.com/altcrauer/opencl_soc_bsp/tree/de0_nano_with_display
Build commands
#To build with the BSP, you have to set AOCL_BOARD_PACKAGE_ROOT
export AOCL_BOARD_PACKAGE_ROOT=/path/to/bsp
#you should see the de0 listed with this command
aoc --list-boards
#if you recompile linux, you need to compile the driver in opencl_soc_bsp/c5soc/driver
make KDIR=path/to/linux/src
4.Mandelbrot application source code
This git repository includes theOpenCLkernel code and the application code. The source code is based Mandelbrot example from the AlteraOpenCLdesign examples page.

branch: master
git web link:https://github.com/altcrauer/mandelbrot_demo.git
Build commands
#set this env var
export AOCL_BOARD_PACKAGE_ROOT=/path/to/bsp
#build aocx with this command
aoc device/mandelbrot_kernel.cl --board de0_nano_sharedonly_with_spi_tft
#build host code
