clpeak not working on i.MX8M Plus

HME15769 · ‎01-18-2023

Has anyone successfully tested clpeak on i.MX8M Plus?

I built clpeak on my host PC and copied clpeak binary to my i.MX8M Plus.

When I run clpeak, the Platform, Device, Driver version, Compute units, and Clock frequency are displayed, but all tests have a segmentation fault immediately.

I want to make sure that OpenCL is working properly on i.MX8M Plus.

Note that the OpenCL demo in gtec-demo-frameworks (/opt/imx-gpu-sdk) outputs incorrect results and there is no clinfo in /opt/viv_sample.

I got a same result below.

Hi @Zhiming_Liu

I am using LF5.10.35_2.0.0 with RSB3720 made by ADVANTECH.

I followed these steps to build the image.
