QT swaps Red and Blue channels using linuxfb



  • Hi. Trying to make QT5.4.1 work on Atmel sama5d3 device. Device uses BGR color format. Other applications, for example fbi, writes to /dev/fb0 directly and colors are displayed correctly, but QT swaps R & B channels. Looking at qlinuxfbscreen.cpp I can see what where is no way to change format to BGR. Looks like it is not supported in QT5. Uboot displays logo in correct colors. What I am missing? Any solutions? Software QT rbg switching is very slow.
