[SOLVED] RPI 3 - Touch Functionality Issue

[ElGomo]

Hello my dear tinkerers,

i am quite new to the whole RasPi thing and have now spend a few days to find a solution to the follwing:

I have a RasPi 3B and several (3.5 / 5 / 7 inch) touch screens which seem to be from the waveshare family. (just other noname brands)
The configuration script that was delivered with them is basically the same as for the waveshare screens.

So booting to TC on PiCore 9.0.3 is working without any issues. The screens (Output) are working fine.
I just really can't get the touch functionality to work.
I have persistently(/opt/.filetool.lst) added the conf files in
   /etc/X11/xorg.conf.d/
and
   /usr/share/X11/xorg.conf.d/
as well as
   /etc/inittab
which came with the screens on disks/dowloads

then i also edited the config.txt and the cmdline3.txt on the sd card as described by the manufacturer and tried also many other configurations as suggested in other posts.

The screens are not even listed under evtest. But My Usb Keyboard is listed twice o.o

I have read many older topics that suggested solutions with a certain tft.tcz file and so on but that file is nowhere to be found and it seems that this was for older versions of the board.

I managed to get the original 7" RasPi touch to work easily but the other screens (connected via GPIO) just dont want to work.

Even though this topic might have been up a couple times i would be really thankful for a hint where to look.

Many thanks in advance

Hi ElGomo
Did you try using the search page:
http://forum.tinycorelinux.net/index.php?action=search
to look for:

Code: [Select]

waveshare

also try the picoreplayer forum - lots of info there ...

Thanks for your replies,

i will try to dig up some more information that way and hopefully be able to resolve that issue.

Hello again,
i have been sifting through both forums and only found the same entries i have already found during days of google search.
Some only manage to get the screen output working (witch is already working fine for me). Others are using older versions of the board or the files provided are no longer online. And then there are those that suggest the Setup like i already did it.

If anybody reads this and has by any chance gotten the touch feature to work on the TC Desktop i would be really happy if you shared what i am missing.
Especially why the screen is not popping up as an input device via evtest

Okay i found the solution.
Sorry to not having had enough patience and having started a new thread.

The solution was actually basic.

I forgot to load the input driver modules.

i created my own tft.tcz extension with the files listed here:

i was using the files from the latest kernel
http://tinycorelinux.net/9.x/armv7/releases/RPi/src/kernel/

after creating this and installing it the screen now works like a charm.

Hi ElGomo

... This thread can be closed / deleted

I think I'll mark it as solved instead, just in case someone else runs into a similar problem.
