Boot to Qt doesn't recognize display

  • Hello,

    I am trying to get a 4.3" TFT display working on my Colibri board.

    I have a Colibri iMX7 with Boot2Qt and it does not recognize the display. I have an Colibri iMX6 with Boot2Qt, which does recognize the display.

    Is it possible that the iMX7 image does not support all display types yet? Or do I have to change some setting?

    Hi and welcome to devnet,

    That's a bit vague. What do you mean by "does not recognise" ? Do you have anything showing up on that display ?

  • Hey, I'll try to elaborate,

    With the iMX6 the system boots and the Qt sample application is show on the display.

    On the iMX7 the system boots, but I don't have any video output. My display is completely white (I think that is only the backlight).

    With "recognise" I mean it doesn't seem to make use of the display.

    I hope this makes more sense.

    Just to be sure I understand correctly, you don't even see any message from the kernel start ? If that's the case it might rather be something iMX7 specific and I'd recommend contacting the folks from Toradex.

  • No kernel output at all. I think it's an issue for Toradex indeed, I will contact them.

    Thanks for your help.
