2019-12-10 Touch not work!

I got a problem with the touch chip XPT2046.There is a strange problem with the chip IRQ pins.

I checked this pin with an oscilloscope and then compared it with a working touch display.

Working:

Not working:

It can be intuitively seen that the waveforms of the two are different, but I haven't found out why.

In order to better find the reason for the touch chip, a separate PCB board for the display screen is specially drawn, which is being produced in the JLC PCB factory. It is expected that the soldering test can be performed the day after tomorrow.
