Version 0.9.0 vs. KeeToch 10.4” Monitor: "Input Not Support" Regression Issue

With version 0.8.1, RPI 3 models B and B+ work fine with a 10.4" KeeTouch monitor (model KOT-0104U-CA4P), but I am having the following problem when I use version 0.9.0: "Input Not Support".

This message appears a few seconds after the card is powered on. After that, the screen shows no images.

  • Thanks for reporting. Is it a fresh installation or update?

    Fresh installation.

  • Please try to flash again & wait for at least one minute. Check if device reboots itself once or twice.

    I waited for over 20 minutes. Nothing happened.

    Some notes:

    1. When the RPI is booted for the first time after flashing card:
      1.1. Coloured splash screen appears;
      1.2. Some system information appears on the screen;
      1.3. The monitor error message appears and then the screen goes completely black – and in over 20 minutes, nothing happened after that.

    2. During subsequent boot attempts:
      2.1. Coloured splash screen not appears;
      2.2. No one system information appears on the screen;
      2.3. The screen goes black and the monitor error message: appears for 3 seconds, disappears for 3 seconds, and reappears for 3 seconds. After that, the screen goes completely black – and in over 20 minutes, nothing happened after that.

  • Thank you for this information.
    Is it possible for you to mount the sdcard on you PC (is it Linux or Windows?) and check the contents of the /boot/config.txt file?

    Booting rpi3's v0.9.0 with the config.txt file from keto's v0.8.1

    • Coloured splash screen appears;
    • Some system information appears on the screen but stops at the following line.:

    [ 24.xxxxxx] init: Starting service 'exec 12 (/system/bin/bootstat)' ...

    Note: The "xxxxxx" indicates a number sequence that changes at each system startup, but the other information on the line does not change after reboot.
