AM3352 QT framebuffer error

Patrick Loef1
Expert 1230 points
Other Parts Discussed in Thread: AM3352, DA8XX, TPS65217

Hello,

I'm using an AM3352 processor with the TI SDK 07.00.00.00.

When I follow the QT wiki page and start the example I get an error:

QScreenLinuxFb::connect: No such file or directory
Error opening framebuffer device /dev/fb0

This is error repeats until I stop the programm.

In my menuconfig the following is turned on:

Device Drivers --> Graphics Support 

<*> Support for frame buffer device -->

    [*] Enable firmware EDID

    [*'] Framebuffer foreign endianness support

    <*> DA8xx/OMAP-L1xx/AM335x Framebuffer support

   [*] Simple framebuffer support.

But this does not help, what can I do?

Kind regards

Patrick

    Hi Patrick,

    Can you attach your boot log to check if there are any error messages related to the framebuffer?

    Best regards,
    Miroslav

    You need to make sure you have the configs enabled that are listed on the LCDC driver page.  Make sure you are aware of whether you would like to enable DRM or fbdev drivers.

    You also need to make sure you have the right device tree entries.  Look in the Porting section of the main LCDC page.
