Hello, Mr Gao:
There was one known hardware issue which may impact touch screen interrupt.
Some information are FYI:
Applies to CPU Cards: MCIMX6QAICPU1 and MCIMX6DLAICPU1
The processor never receives the LVDS touch panel interrupt. A buffer has its power pin unconnected.
Connect interrupt buffer U1514 pin 5 to power rail P3V3_DELAYED.
Thank you very much.
I had close this issue follow your resolution.
And I think it's better to update this to freescale's documents.
Many of my customers haven't know about this.
Glad to see it's helpful.
I will consult with hardware team whether this information was published into the formal document.
We are working on the document. It will be released soon. I will tell the customer.
The document is now available on Community. See SABRE-AI_Touch_Int_Bulletin_v1.pdf.
We are working on the document. Thank you for your feedback.
