Black display and unable to update firmware



  • The display of my a 4.3" PanelDue stays black. There is no blacklight or any indication of it being on when plugged into the PanelDue Display Controller Board v3.0a connected to my Duet Wifi. Issue persists when connected via the 4 pin PanelDue connection as well as the serial cable to the LCD port as well as when connected with both cables.

    I connected it via usb instead of the Duet WiFi for power and the display still does not turn on.

    Followed https://miscsolutions.wordpress.com/paneldue/ to try and update the firmware from a Raspberry Pi with the following steps and results, and the backlight remained off the whole time:

    Connected to Raspberry Pi via USB
    Pressed and held the Erase button of the PanelDue for at least one second, then
    released the Erase button, then pressed and released the Reset button.

    Terminal:

    pi@protoPi:~/PanelDueFirmware $ wget https://github.com/dc42/PanelDueFirmware/releases/download/1.21.3/PanelDue-v3-4.3.bin
    pi@protoPi:~/PanelDueFirmware $ dmesg
    [ 781.614164] usb 1-1.1: new full-speed USB device number 6 using dwc_otg
    [ 781.747885] usb 1-1.1: New USB device found, idVendor=03eb, idProduct=6124
    [ 781.747910] usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
    [ 781.753224] cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device
    pi@protoPi:~/PanelDueFirmware $ bossac --port=ttyACM0 -e -w -v -b PanelDue-v3-4.3.bin
    No device found on ttyACM0
    pi@protoPi:~/PanelDueFirmware $

    If I short the Always on solder pads together the backlight comes on but nothing is displayed.

    The display worked with no issues since purchased a couple months ago until now.

    Are you using the correct version of bossac? You need version 1.8 to program a version 3 PanelDue.

    It's normal for the display to be black when the PanelDue controller is not programmed.



  • @dc42 The newest version of bossa-cli i could install via aptitude or apt-get was 1.1 so I decided to use the GUI version of BOSSA on my Mac, checking the options to Erase All, Boot from Flash, and Lock, and that worked! Thanks!



  • I do have the same Problem with two Panel DUE 4.3"
    we had the problem that when we pressed settings the macro tab would open so my college erased the frimware.
    Now I flash the panel due but the display is still black, the comand window reported Verify successful.

    the bossa GUI is not able to write, while writing i ll get "flash comand failed"
    the bossa GUI also dosn t give me write options where I can set or unset boxes.

    I have no Idea what to try nexted.

    PS.
    It took me several hours to find out that the comandline does not accept path with spaces like "...\3D Printer..."

    Check that you downloaded the correct firmware, either the v2 or the v3 4.3" version depending on the revision of your PanelDue controller board, from here https://github.com/dc42/PanelDueFirmware/releases and that the downloaded file size matches the size shown on that page.

    This is a known issue with using Bossa on computers with high-resolution displays.

    It took me several hours to find out that the comandline does not accept path with spaces like "...\3D Printer..."

    it may work if you enclose the path in double quote characters. You may also have to use / in the path instead of .



  • hey,

    we have the panel Due v3.0a and i tried "PanelDue-v3-4.3-nologo.bin" and "PanelDue-v3-4.3.bin" FW
    for the final flash I used:
    "C:\Program Files (x86)\BOSSA\bossac.exe" --port=COM14 -e -w -v -b C:\PanelDue43Zoll\PanelDue-v3-4.3-nologo.bin
    which reported very successful

    What happens next if you press the Reset button or power the PanelDue down and up again? The Bossa port should disappear from Device Manager and the display should work. But you have to reset the board first, because Bossac is unable to reset a SAM4.



  • Hello

    When I press the reset button the bossa port disappears, but the Display is still black. The display is also black when pluged into the DUET WIFI.
    after pressing the erase button and then pressing reset the bossa port is back again.

    This is for both displays

    best regarts

    Please check that the size of the downloaded binary you are trying to install matches the size given on the Releases github page that you downloaded it from.



  • @dc42 perfect it worked (my downloaded file has 201 Kb but an git it only has 90) re downloaded the file and then it worked, thanks
