    Hi,

    I have compiled QT 5.2.1 from git with opengl ES2 support for a imx51 platform.

    I have a QML quick2 project from earlier which has proven to run successfully on Linux/Win before and I tried to run the same project on the embedded platform and I get the following messages:

    @QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
    QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed
    EGLFS: Unable to query physical screen size, defaulting to 100 dpi.
    EGLFS: To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters)

    Color formats don't match. Falling back to copy forward swap.@

    At this point the application is displayed on the screen och everything is fine, except I can see some miss-coloration in some places.

    I tried fbset with a couple of diffrent options and testes -depth 16 32 och also to increase vertical size to 3/4 times but all it does seems to make the image even worth.

    Do you guys have any idea what this could be?

      bq. QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
      QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed

      when configuring Qt: -/configure … -no-iconv
