@T_Eng Also to say that my GUI is Qt Quick Qml code and I am trying to fill a TextField qml type

What PDA device ?

I have faced the same issue, however I resolved it by following the instructions from the below link: http://pifuge.com/ubuntu/cPB-error-gnutls-handshake-failed-when-connecting-to-https-servers

@SGaist Thank you for reply. As you said, we shall optimize Qt and DFB. Thank you.

Cross-compiling is one thing, how did you install Qt on your board ?

I finally got to solve this by myself. I only had to add 'libqgfxtransformed.so' to my target's /usr/lib/qtopia/plugins/gfxdrivers folder. I then ran my app using the '-qws -display transformed:rot90' switch and I got my rotation done!
