EGLFS display output setup with Intel NUC



  • Hey guys,

    I have question about display output resolution setup with Intel NUC.
    I read the documentation:
    http://doc.qt.io/QtForDeviceCreation/qtee-customization.html
    and not find method to customize resolution with Intel NUC.

    I am working on application run under eglfs (boot2qt) on Intel NUC and it require to connect to a HDMI display EDID shows supports 1920x1080, 1280x720, 1024x768, and 800x600, (it's actually go through HDMI and MIPI converter) Is there anyway to setup resolution to 480x600? I've tried kernel command line:

    drm_kms_helper.edid_firmware=edid/480x600.bin

    480x600.bin is made by modeline2edid and modeline was generated by cvt on my host machine.

    and it's not working. Error occurs during boot:

    ERROR Requesting EDID firmware "edid/480x600.bin" failed (err=-2)

    I know this method could work because I've tried the sample edid.bin file (1280x1024.bin) and the display show picture with 1280x1080 set.
    (default/preferred is 1280x720)

    Or maybe there's other way to force resolution with Intel NUC?
