VIM1
41

try this

42

Thanks! So how can I build such image for EMMC for example ? What module and how should I enable to add touchscreen support ?

43

try this image if this works. Then just need to change one file in the files provided by khadas…

I will post the entire steps tomorrow

44

Alright. I will test it tomorrow morning.

45

Well, I’ve tried new image, but for some reason modprobe still doesn’t see module

root@Khadas:~# uname -a
Linux Khadas 4.9.224 #2 SMP PREEMPT Fri Jun 5 09:51:04 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

root@Khadas:~# modprobe -r usbtouchscreen
modprobe: FATAL: Module usbtouchscreen not found.

And touch doesn’t work

46

Can you try lsmod command?

47

try this image

I have confirmed the module is there

48

Sorry for long answering.

Alright! Thanls , I’ll test

50

So module seems to present now

root@Khadas:~# modprobe -r usbtouchscreen
modprobe: FATAL: Module usbtouchscreen is builtin.

But touch doesn’t seem to work again. Should I enable something else?

51

We need to find out what kind device it is, Can you connect it to computer and open device manager, try to see What kind of device it is touchscreen or pointing device ?

52

It is HID sensor monitor device as I can see in Win10 Device Manager

53

Could you show me a screen shot, I believe it is a pointing device

54

HID compatible touch screen

My Win10 is in Russian
image

55

ok could you read this article and try what they have given in it, it is for Arch but maybe it could work in ubuntu,

First,

xinput list --long

once you have identified the device,

xinput disable/enable <device_id>

or

xinput disable/enable <“device_name”>

56

Oops make a mistake in build… It should have been a module…
Can you give 45 mins to rebuild…?

57

Sure, no problem. Thanks

58

meanwhile can you try this command
echo "blacklist usbtouchscreen" | sudo tee -a /etc/modprobe.d/blacklist.conf

@ClownMik Also can you try ‘lsusb’ on Rpi with the sametouch screen…?

Showing just as STmicro is a bit weird can you check once in RPI

59 
root@Khadas:~# echo "blacklist usbtouchscreen" | sudo tee -a /etc/modprobe.d/blacklist.conf
blacklist usbtouchscreen

I dont have RPi =(

60

then where did you test the touch screen…?
