There is the following description.

Connect the touchscreen ribbon to the board's touchscreen interface, paying attention to the wire sequence.
Then execute:
/opt/touch.sh # Load the touchscreen driver
Followed by:
echo 2 | evtest
Touching the screen will display specific coordinates in the terminal.
For reading coordinates and touch events, refer to the input section in /opt/src/vendortest.

In release of the repository here, 2024-05-28-17-33-82a0b7.img.xz is empty under the opt folder.

I want /opt/touch.sh and /opt/src/vendortest files, so I would like them to be made public.
