Dear @LEADTECH,
Concerning your first issue I believe you issued this question here before. Were you able to try out my suggestions? 
There are generally three ways to run the Qt framework on Toradex modules:
- The Boot to Qt software stack (Getting Started with Qt | Toradex Developer Center)
- Toradex Torizon (Qt on Torizon OS | Toradex Developer Center)
- Toradex Reference Images for Yocto Project (Our multimedia reference image contains a Qt framework BSP Layers and Reference Images for Yocto Project Software | Toradex Developer Center)
Please let me know how you fare on these two subjects
Best regards
Collin
