Tiny Core Base > Raspberry Pi

piCore 16.0 and Raspi Touchscreen.

(1/4) > >>

MrPorcine:
I'm trying to get the Raspberry Pi 7" touch screen to work (not the newer Touch Display 2). It displays text and graphics fine. So far no touch input.

I have a working piCore13 where the display does touch correctly. When I look at the Xorg.0.log, with the piCore 13, Xorg loads a module called "raspberrypi-ts". Here's the line in the log:

--- Code: ---Adding input device raspberrypi-ts (/dev/input/mouse0)
--- End code ---

There is no such line in the log for the piCore 16. When I look at the list of optional tcz in each version (13,16) the list is exactly the same.

If anyone knows how to make this work it would be really helpful.

I split this topic off.

Comparing piCore 13 to 16 is like night and day in regards to video drivers.

You need to be using the vc4 driver base in piCore16.  What do you have in your config.txt, and what extensions do you have load3d?

MrPorcine:
cmdline.txt has:
--- Quote ---dwc_otg.fiq_fsm_mask=0xF dwc_otg.lpm_enable=0 console=tty1 root=/dev/ram0 rootwait quiet nortc loglevel=3 noembed
--- End quote ---
config.txt is:
--- Code: ---# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# RPi PI0-1-2 are not supported on this image.

I'm using a pi 3B+.

Paul_123:
You need to uncomment this line in config.txt


--- Code: ---#dtoverlay=vc4-kms-v3d
--- End code ---

You also need more extensions.


--- Code: ---touchscreen-KERNEL.tcz   (This will load graphics-KERNEL.tcz as well)
flwm.tcz   (You need some sort of window manager)
aterm.tcz 
Xorg.tcz   (I would use Xorg-3d.tcz)

--- End code ---

MrPorcine:
Maybe a missing module? When I look at Bookworm for the Raspberry Pi (same hardware), Xorg appears to be using a module "edt_ft5x06". I haven't located it in piCore16.
