Hello Huh,
Please check the QT page:
Qt for Embedded Linux | Qt 5.11
Also in
Device Drivers -> HID Devices -> Special HID drivers -> HID Multitouch panels as an embedded driver (*) in my Kernel configuration, and then added touchscreen's Vendor ID and Device/Product ID to the kernel drivers table and rebuilt the Kernel.
this is the config file:
#
# Input device support
#
CONFIG_INPUT=y
# CONFIG_INPUT_FF_MEMLESS is not set
CONFIG_INPUT_POLLDEV=y
# CONFIG_INPUT_SPARSEKMAP is not set
# CONFIG_INPUT_MATRIXKMAP is not set
#
# HID support
#
CONFIG_HID=y
# CONFIG_HID_BATTERY_STRENGTH is not set
# CONFIG_HIDRAW is not set
# CONFIG_UHID is not set
CONFIG_HID_GENERIC=y
#
# USB HID support
#
CONFIG_USB_HID=y
# CONFIG_HID_PID is not set
# CONFIG_USB_HIDDEV is not set
And when you do lsmod output does not show hid_multitouch module - because you built as an embedded driver (not as a module).
Regards
