OpenCl support on the pi for opencv

Hello,
I have installed and run Opencv on the Pi. Now I want to use its GPU using opencv as opencv has cuda and Opencl support.I have looked at many raspberry pi discussions on using the GPU with Qpu etc But is it possible to write an Opencl driver for the Pi?

Re: Unable to toggle GPIO pin in raspberry pi 2 board

We did a "git pull rebase" for the kernel and it worked like old. Thank you all.

I ran sudo apt-get update, sudo apt-get upgrade and sudo apt-get dist-upgrade but I am still not able to set the pin value using our C++ code which was working on the earlier raspberry pi ...

Re: Unable to toggle GPIO pin in raspberry pi 2 board

The kernel version is the latest 3.18.7 - 755. Is this sufficient or should we still update the gpio libraries. How do we update the GPIO libraries???

raspicam board connector pinout

Hello,

I am thinking of working with the strobe pin on the camera.There is a 24 pin tiny connector that sits on the camera board (not the flexible 15 pin connector).I need the pinout for this 24 pin connector.Could some one help me here.I searched online but I could not find it.
