Darknet in OpenCL on Beagleboard AI

Hi, today I have a very interesting single-board computer named Beagleboard AI.So far my favorite single-board computer was Darknet in OpenCL on Asus Tinker Board S. Let’s login via SSH on it on the flashed system on the SD card and configure it. I connected to it also hardware webcam Logitech C920… but just before I will show you the design and then command prompts to make it use Darknet on OpenCL

Let’s set up it now.

passwd #to change the default password
sudo su – # to become a root :D.
apt update
apt list –upgradable # optional to check what will be updated
apt upgrade
apt install cmake
apt install ocl-icd-opencl-dev
apt install opencl-headers
apt install libclblas-dev
# if there is kernel in update list do a reboot and start over
###
reboot # or exit from root command prompt
mkdir github
cd github
mkdir sowson
cd sowson
git clone git clone https://github.com/sowson/darknet.git
cd darknet
vi CMakeList.txt # or nano or joe or vim… set DARKNET_ARM=ON
vi src/opencl.h # add in ARM definition: #define CL_TARGET_OPENCL_VERSION 220
mkdir build
cd build
cmake ..
make
cp darknet* ..
cd ..
rm -rf build
mkdir ../../../weights
wget https://pjreddie.com/media/files/yolov2.weights
mv yolov2.weights ../../../weights/
# enjoy! :F

Keep in mind this computer is strong but, you have to use extra fan I did not have yet… over thermal kernel panic is possible… but this is my setup…

Beagleboard AI Mine

There is one more thing… two days ago OpenCL 3.0 was released at Khronos Group Site. And the last news is that Beagleboard AI computer has OpenCV support, I am not sure if you noticed that… Now you can play with Darknet on OpenCL 😀
