Unsolved Qt5 +weston +keyboard on embedded device (IMX6)

[zedroid]

Hello!
My question is mainly not about development. I am integrating Liri-files inside system based on weston.
When I run application (here and below liri-files) as main in the system (here and below system based on IMX6 built by Yocto rocko release, qt5,9 or 5.12) the keyboard handled perfectly. When I start application from launcher in weston as (/app -platform wayland) keyboard is not handled at all. I have tried:
-set QWS_KEYBOARD='linuxinput=/dev/inpunt/event0'
-set -plugin evdevkeyboard=/dev/inpunt/event2
and such things without any effect.
How can correctly handle keyboard for weston based systems?
