Hi All,

I want to test GPU function in INX8M Nano customer board without any display device.

I try to use the /opt/imx-gpu-sdk/ and /opt/viv_samples/ tool to test GPU , but most of the tools cannot be executed and return the following log.

vdk_create_display(955): wl_display_connect failed

 

Thanks,
