    But I don't get it done to copy files directly to the USB stick hooked up to the BOSS2 via SAMBA or whatever it takes. Do you know how to do that?
    I'm working on it now.

    I'll start a new thread

    As far as I can tell, the first touchscreen works fine on everything but PiCorePlayer, which suggests to me an incompatibility specifically with something in the PiCorePlayer build.

    The manufacturing date of the first (problem) touchscreen appears to be 2012, and the second (working) one appears to be 2009. Attached is a picture of the numbers printed on the back of the screen.

    I've also tested it on the following versions of Tiny Core (downloaded directly from tinycorelinux.net), and it works with no issues. I get the rainbow screen on boot, followed by the boot process text.
    TinyCore 12.0 64 bit
    TinyCore 13.0 32 bit
    TinyCore 13.0 64 bit

    Any suggestions? I'm out of ideas for things to try.
    What rpi board are you using? If you are using the rpi4, what is the bootloader version?
    piCorePlayer a small player for the Raspberry Pi in RAM.

    How about trying pCP 6 (or older)?
    I agree, very odd!

    You are correct, I can repeat it just by switching the SD card and not touching anything else. Today I tested using the same SD card, just writing a new image to it.

    pCP 6.1.0 - same behaviour - grey screen
    pCP 5.0.0 - no boot, black screen (doesn't support Pi 4?)
    back to Tiny Core 12.0 64 bit (on the same SD card) - works

    I'm using a Pi 4B. The bootloader version is Sep 3 2020 13:11:43
    I also tried on a second Pi 4B running bootloader version Apr 29 2021 17:11:25, with the same results.

    Thanks

    Just another idea to check ():
    There are two generations of these displays: With the newer one you can control the brightness of the backlight while the first generation has only an on/off capability. In both types, the backlight is controlled by the content of the file '/sys/class/backlight/rpi_backlight/brightness'.
    For the first generation, a value greater than '0' will switch on the the backlight while '0' means 'backlight off'.
    The second generations accepts values between 0 and 255. The higher the value the higher the brightness. Now comes the important part for you, kbpro: values lower than 10 (or 11) lead to a black (or dark) display what is similar to the behaviour of your display.

    Hence, I suggest to check the value in the file '/sys/class/backlight/rpi_backlight/brightness' whether it is in the range of 1 ... 10. If yes, then choose an higher one (50 is more than sufficient.

    Thank you for the suggestion jd68. I just checked and it is set to 255.

    One note from the distributor (thanks buyapi.ca) - they don't think that the numbers on the back of the panel correspond to a manufacturing date, so that may be a red herring.

    Does your SSD have a GPT partition table? Then it is easy to get it to work.
    You have to install "util-linux.tcz" to get it to work!
