Error: Cannot fit kernel(s) on device

​​Hello everyone,

I want to implement some function of open source code with DE1SoC.

The project uses opencl kernel to program the FPGA and have a host program to call the kernel.

But when I build the project, there is an error said 'Error: Cannot fit kernel(s) on device'. While the host program and .aoco files were generated successfully. The details are as below:

Error: Cannot fit kernel(s) on device
make: ***  Error 1

And the last several lines in the log file shows below (Seems there is no error?):

I have build the hello-word demo and boardtest demo successfully which are contented in the de1soc_opencl_v02.pdf (http://www.terasic.com.cn/attachment/archive/836/de1soc_opencl_v02.pdf).

I use AOCL-16.1.0.196-windows and DE1 BSP for Altera SDK OpenCL 16.0.

I totally have no idea about this problem. I have found very little solutions about this.

Would you give me some suggestion?

Thank you!
