  • LCD replacement and KERNEL/Driver modification needed (Need Help!)

    I need help in re-configuring the default or built-in Screen resolution of an RK3066 Fnf iFIve tablet.
    The Tablet 7" original LCD broke, I manage to interface or connect a 15" LCD from a Laptop.
    The 7" was tagged "Normally Portrait" with [email protected] resolution, while the 15" LCD replacement
    was tagged "Normally Landscape" with resolution of [email protected]

    Yes there was at least 80% success since it is able to show a fine crisp 800(480-missing)[email protected]

    I cannot find the source-code for the RK3066 specifically for the Fnf mini 2, I have seen and downloaded source code from GIT pertaining to RK30 with indications that the wifi may not work, and that it is still in progress. If I am to dwell on the given source, I may be able to setup the Display configuration, yet with no wifi.

    I am hoping someone may be able to guide me on how it is best for me to tackle my project 15" LCD remake.

    I have seen an update zip that alters the HDMI resolution. But I am afraid without the source code I will not be able to derive
    an update.zip to fix the internal or default Resolution.
    #!/system/bin/sh
    #!/system/xbin/sh

    # Display MOD ver. A (Refresh Rate 50Hz) by BuLLeT_93

    mount -o remount,rw /
    mount -o remount,rw rootfs
    mount -o remount,ro /system
    busybox mount -o remount,rw /
    busybox mount -o remount,rw rootfs
    busybox mount -o remount,ro /system

    #Orginal Strings from the update.zip
    #sleep 7
    #busybox echo powersave > /sys/devices/platform/g3-display.0/devfreq/g3-display.0/governor;
    #busybox echo 50 > /sys/devices/platform/g3-display.0/devfreq/g3-display.0/max_freq;
    #busybox echo 50 > /sys/devices/platform/g3-display.0/devfreq/g3-display.0/min_freq;
    #busybox echo 0 > /sys/devices/platform/g3-display.0/devfreq/g3-display.0/polling_interval;
    #busybox chmod 444 /sys/devices/platform/g3-display.0/devfreq/g3-display.0/polling_interval;
    #busybox chmod 444 > /sys/devices/platform/g3-display.0/devfreq/g3-display.0/polling_interval;

    #My theorize strings, not yet tested
    echo "U:1280x800p-59" > /sys/devices/platform/rk-fb/graphics/fb0/modes
    #since the MODES files generates U:800x1280p-59 thru CAT MODE
    Yes, the Tablet also has an HDMI output. So I thought I could apply to the Default Display as well

    I have setup the tablet for wireless ADB and VNC for control.

    I specifically wanted to either Rotate the Screen orientation thru the Driver not via the Virtual display (afaik, Surfaceflinger)
    I am able to find and confirm that the default display was thru the FB0 via $cat /dev/urandom > ../fb0

    So, just to confirm. Where to I best make the Screen resolution adjustment?
    Thru BOOT = may require me to input boot arguments.
    Thru KERNEL = lack of source code
    POST boot/Kernel = kindly suggest any alternative

    What I have tried:
    Make use of Screen Resolution Changer = mostly FC's and the Displayed screen width and lenght does not change. Only the DPI change when I setup a diff Density.
    Screen Rotate = Only the 800x800 pixels reacts, not the other 480 pixels.

    What I have:
    Windows 10x64 alongside Ubuntu 15 with Build environment and complete dependencies
    Have Downloaded GIT resources from OMEGAMON and the REST of Source Code providers for RK30
    Some Update.zip that alters a 02bl93_LCD
    Complete CWM ROM backup
    Official ifive-mini2-1.3.7.tw.app.1.3 Firmware
    RKtools/CRC

    Your Help will be greatly appreciated since I have been woking on this for weeks no and sleepless nights.Click image for larger version
