    Dear FS-Support,


    I have been testing on this pre-release and have problems getting any output on my display(Blank white screen). I'm following the instructions above.


    I'm using the picocoremx8mpr2-lcdif-j070wvtc0211.dtb which I guessed that was matching the display that comes with the evaluation kit.


    I have modified the imx8mp-lcdif-j070wvtc0211.dtsi. Please see attachment.


    Does this device tree match the display of the evaluation kits?


    Is the pre-release supposed to work on the imx8mp evalkit and running with wayland/weston?


    Br,

    Hello Paul,


    yes the j070wvtc0211 is supposed to work with the picocoremx8mp eval kit and the pre release.


    In your device tree you disabled lvds1 and lcdif1.

    For the picocoremx8mp the default LVDS port is DSI_B, which are the middle pins of the display connector.

    DSI_B is also connected to lvds1 and lcdif1 of the SoC.


    Do you have a cable, where the blue/white colored wires are connected to the middle of the connector, and not the edge?

    Installing the Pre-Release

    !!ATTENTION!!

    Please make sure to update your board to uboot-fsimx8mp-Y2023.03 and nboot-fsimx8mp-2023.05before installing the pre-release.

    The easiest way would be to follow the instructions at

    i.MX8M-Plus Recovery Tool


    You could also install the new pre-release uboot-fsimx8mp-Y5.15-pre.1 first, reset the board and install the nboot-fsimx8mp-2023.05.

    Installing nboot-fsimx8mp-2023.05 first will break the board!


    You may have to reconfigure the uboot environment so please make sure that everything is set corectly after installing the new u- boot.
