External touch screen display not working with Android 11 on board 2S

Recommended Posts

Hello! Exciting to be using the Tinker Board 2S! My application requires Android 11 with an external touch screen display. The issue I am facing is that the touch screen input to Tinker board 2S via the USB does not work. Touch input is not detected. The same setup works fine on a Blackberry Pi 4 running Emteria Android. So, I have concluded that it must be some issue/setting on the Android 11 running on the Tinker Board 2S.

FYI, a wireless mouse/keyboard work just fine on 2S.

Anyone with experience using an external touch screen monitor via USB?

Thanks!

I am facing the same problem with my ASUS Tinkerboard 2S.

My observations so far:

  • Touch interface through USB doesnt work.
  • If I connect keyboard/mouse BEFORE the touch usb, keyboard/mouse work.
  • Once I connect the touch USB, nothing works.

Any help with this problem would be great.

Thank you

Has there been any updates on this topic? I am running into the same problem. (Tinkerboard 2)

@tooz it is impossible to get any information out of the Tinkerboard, it completely stops working and needs a power cycle before it can operate again.

I am using a 7" Hicenda HF7SMP-7CTP TFT diaplay with touch, attached is the HDMI driver board that has a Micro USB 5V and a Micro USB 5V + Touch.

When i connect it to the one with touch is when all the problems start happening.

Thanks!

hello @wesselTOP

we will need more logs to debug the issue

1. to collect logs via tty uart: 

 

2. to collect kernel logs with adb shell command: 

adb shell dmesg > kernel.log
