How to Do

Environment

  • Operating System : Ubuntu 18.04 x64
  • Quartus Prime : Quartus Prime Lite 18.1 (QuartusLiteSetup-18.1.0.625-linux.run standalone)
  • OpenCL SDK : Intel FPGA SDK for OpenCL 18.1.0.625 (AOCLSetup-18.1.0.625-linux.run standalone)
  • Quartus Path : /opt/intelFPGA_lite/18.1
  • SDcard Image : c5soc_opencl_lxde_fpga_reconfigurable_20201027.zip
  • FPGA Board : Terasic DE10_Nano Version C
  • OpenCL BSP Name : de10_nano_sharedonly_hdmi
  • OpenCL Demo : Mandelbrot
  • MSEL[4:0] : 01010 -> SW10(1 to 6) on,off,on,off,on,N/A

Tools install

Windows x64

  • Quartus Prime Lite 18.1
  • Intel FPGA SDK for OpenCL 18.1
  • SoC Embedded Design Suite (EDS)

It's easy to use linux commands (arm-linux-guneabihf-gcc,make) in Soc_EDS_command_shell.bat on windows.

Linux (Ubuntu 18.04 x64)

  • Quartus Prime Lite 18.1
  • Intel FPGA SDK for OpenCL 18.1
  • arm-linux-gnueabihf-gcc
  • arm-linux-gnueabihf-g++
  • u-boot-tools
sudo chmod 777 /opt
./QuartusLiteSetup-18.1.0.625-linux.run --mode text --installdir /opt/intelFPGA_lite/18.1  --accept_eula 1
./AOCLSetup-18.1.0.625-linux.run --mode text --installdir /opt/intelFPGA_lite/18.1  --accept_eula 1
sudo apt update
sudo apt install minicom u-boot-tools gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf libncurses5-dev make lsb uml-utilities git

Write Image to MicroSD card

  1. show sdx device
ls /dev/sd*
  1. insert sdcard to PC and show the sdx device again, the new device is sdcard

  1. unzip the Image and write it to sdx with dd (change /dev/sdx to the new device in step 2)
unzip c5soc_opencl_lxde_fpga_reconfigurable_20201027.zip
sudo dd if=c5soc_opencl_lxde_fpga_reconfigurable.img of=/dev/sdx status=progress bs=1M

Compile OpenCL Kernel

  1. copy the hardware bsp to /opt/intelFPGA_lite/18.1/hld/board/c5soc/hardware
git clone https://github.com/thinkococ5soc_opencl.git
cd c5soc_opencl
cp -rf de1soc_sharedonly_vga /optintelFPGA_lite/18.0/hld/board/c5soc/hardware
cp -rf de10_nano_sharedonly_hdmi /opt/intelFPGA_lite/18.0/hld/board/c5soc/hardware
cp -rf de10_standard_sharedonly_vga /opt/intelFPGA_lite/18.0/hld/board/c5soc/hardware

  1. source environment and check bsp

About environment，write the following to env.sh file and change the paths for your situation. Source it using "source env.sh" before compiling .aocx and .rbf.

export INTELFPGAOCLSDKROOT="/optintelFPGA_lite/18.0/hld"
export QSYS_ROOTDIR="/optintelFPGA_lite/18.0/quartussopc_builder/bin"
export QUARTUS_ROOTDIR_OVERRIDE="/optintelFPGA_lite/18.0/quartus"
export PATH="$PATH:{QUARTUS_ROOTDIR_OVERRIDE}/bin:{QUARTUS_ROOTDIR_OVERRIDE}/linux64:{INTELFPGAOCLSDKROOT}/linux64/bin:{INTELFPGAOCLSDKROOT}/bin:{QSYS_ROOTDIR}"
export LD_LIBRARY_PATH="{INTELFPGAOCLSDKROOT}/host/linux64lib:${AOCL_BOARD_PAKAGE_ROOT}/linux64lib:${LD_LIBRARY_PATH}"
export AOCL_BOARD_PACKAGE_ROOT="{INTELFPGAOCLSDKROOT}/board/c5soc"
export QUARTUS_64BIT=1

  1. compile the Mandelbrot kernel on PC
cd c5soc_opencl/application/mandelbrot
aoc device/mandelbrot_kernel.cl -o bin/mandelbrot_kernel.aocx  -board=de10_nano_sharedonly_hdmi -v -report 


aoc device/grayKernel.cl -o bin/grayKernel.aocx -board=de10_nano_sharedonly_hdmi -v -report
aoc device/sobel.cl -o bin/sobel.aocx -board=de10_nano_sharedonly_hdmi -v -report
aoc device/mandelbrot_kernel.cl -o bin/mandelbrot_kernel.aocx  -board=de10_nano_sharedonly_hdmi -v -report 
aoc device/camera_sobel.cl -o bin/camera_sobel.aocx -board=de10_nano_sharedonly_hdmi -v -report
  1. compile ok
ls bin/mandelbrot_kernel/top.rbf
ls bin/mandelbrot_kernel.aocx

Update the MicroSD card

  1. delete the opencl.rbf and socfpga.dtb in the sdcard

  1. copy the de10_nano_socfpga.dtb to sdcard and rename

  1. copy the top.rbf to sdcard and rename

  1. make a foldor mandelbrot_run in sdcard and copy mandelbrot_kernel.aocx to it

Build the mandelbrot host on DE10_NANO

  1. boot the de10_nano and connect serial port (USB-UART) to PC
sudo minicom -D /dev/ttyUSB0 -8 -b 115200

  1. login with user:passward(root:root)

  1. source the env on de10_nano and build the mandelbrot host
cd /root
source init_opencl_18.1.sh
cd /mnt/application/mandelbrot
make host

  1. copy the host to work dir
cp bin/mandelbrot /mnt/mandelbrot_run

run mandelbrot on desktop environment

  1. login on desktop environment with (knat:knat)

  1. open LXterminal

  1. source the intel fpga opencl sdk env
cd /root
source init_opencl_18.1.sh

  1. run mandelbrot
cd /mnt/mandelbrot_run
./mandelbrot -w=800 -h=640 -c=32

  1. the result

run demo by aocl program

  1. connect UVC usb camera and USB-UART to DE10_NANO.then,open the uart terminal on PC
sudo minicom -D /dev/ttyUSB0 -8 -b 115200
  1. stop lightdm and program by aocl program(USB-UART terminal)
cd /root
source init_opencl_18.1.sh

cd /mnt/camera_sobel_run

service lightdm stop

rmmod -f altvipfb
rmmod cfbfillrect
rmmod cfbimgblt
rmmod cfbcopyarea

aocl program /dev/acl0 camera_sobel.aocx
 
modprobe altvipfb
service lightdm start
export DISPLAY=:0

  1. login again

  1. open LXterminal

  1. source the intel fpga opencl sdk env and run camera_sobel
cd /root
source init_opencl_18.1.sh
cd /mnt/camera_sobel_run
./camera_sobel -v

  1. the result
