IMX6Q的opencl使用问题

[wwfdzh2012]

请问有没有IMX6Q的opencl方面的详细指导书，官方的文档实在太多，分不清楚？

Hi,

As start point, You should try the openCL hello world:

OpenCL Hello World 

It demonstrate how to create a basic OpenCL based application. Other basic and Complete code is on: opencl/ocl_hello_world at master · andreluizeng/opencl · GitHub 

For information related to the OpenCL EP API, access the Khronos website: https://www.khronos.org/registry/OpenCL/specs/opencl-1.2.pdf 

I hope the information shared in this post can help and give you some directions in your future projects.

regards

I refer to the document： White Paper | Get started with OpenCL on i.MX6 , and do it step by step,,I found it works default for linux-3.0.35,but my I.MX6 board's linux kernel version is 3.14.52, I use the arm-linux-gnueabihf-gcc to compiler the linux kernel, because of the faster than arm-linux-gnueabi-gcc. So I tried to use the compiler to compile the BSP source: L3.0.35_4.1.0_130816_source.tar.gz, but I failed, it tells me about that my configuration was wrong.

how to compile the BSP of linux kernel 3.14.52 with arm-linux-gnueabihf-gcc compiler, how to config?Thank you!

translate to English：I want to use the OpenCL to compute many 2D data(no standard video or Image)，but I can not find the documentation about that，so, please tell me about how to use it. thank you!
