i.mx6q darknet opencl error: out of resource

I'm porting GitHub - lincolnhard/darknet-clblast: Run darknet using OpenCL backend with CLBlast sgemm

on i.mx6q board, I got some errors, here's the log:

CLBlast: OpenCL error: clCreateKernel: -5

the opencl error -5 means 'out of resource'

I traced the code that caused the problem was the attached file 'xgemm_direct_part3.opencl'

Is there any document about i.mx6q gpu for opencl resource limitation?

How can I optimize the xgemm opencl code to use less resources?

Any suggestion would be appreciated.

Hello Chris Lee,

There are a couple of GPU tools. There is a GPU Demo Framework SDK which you can find on the link below (please note you may need to login to download).

There is also a profiler tool for the GPU available on the link below (for Kernel 4.1.15)

Darknet is not currently supported on the i.MX6Q BSP. Maybe some Community users can comment on this but perhaps you should ask this question in forums more focused on Darknet.
