i'm not an expert in this field, so sorry if i'm wrong with some terms, and i need some help with my problem.
Using buildroot-at91, i succeeded to create a bootable SD card with AT91 bootstrap + U-boot + linux kernel 4.14.73 (linux4sam 6.0).
Also i succeeded to install Qt 4 and relative demos.
The problem is that when i start one of the Qt demos, the lcd screen show the Qt application but the touchscreen doesn't work (but the touch buttons K1, K2, K3, K4 yes).
During my investigations, i saw that the /dev/input/touchscreen0 (where i think should be the touchscreen input device because the factory image) doesn't exist.
Also i check the make configuration running from the buildroot-at91 folder:
Code: Select all
that i think should be there if i check the old linux kernel options here: https://how-to.fandom.com/wiki/How_to_c ... vers/input.
Maybe the linux kernel 4.14 doesn't have this option? Or i'm mistaking somewhere?
