Hi All,

I got the following error when trying to use Touch. I am using the IMX8QM board with Android 9 Automotive OS.

imx-dpu-crtc imx-dpu-crtc.1: flush - FrameGen requests to read empty FIFO

Thank You,

Vinoth S,

Hi Vinoth

checking internally I found that such error may happen due to

"ERR050183: DC: 4Kp60 performance limitations"  Mask Set Errata for Mask 1N94W

so recommendation to avoid  usage VPU and GPU altogether with 4K@60fps display.

Best regards
igor

Thank You Igor for the reply,

Do I need to do any configuration in Touch Driver to resolve this type of error?

Sometimes applications (not native application only custom application ) also got crashed when touch connected with a display.

Will you please give some input if you have any Idea regarding the application (not native application only custom application ) crashed when touch connected with a display.

Thank You,

Vinoth S,

Hi Vinoth

 

I think you should try to debug it using

Linux/Android   documentation
i.MX Software and Development Tools | NXP

Yes Igor,

We start already. One of my application developers found ANR (Application No response) from the Application manager. Maybe they subscribe to the touch input for this particular fragment. 

Thank You,
