im building a LDO rev d voron 2.4 and it uses a BigTreeTech Pi TFT43 v2.1. ive followed the steps in the LDO documentation (https://docs.ldomotors.com/en/guides/btt_43_rotate_guide) to rotate the screen but it hasn't worked. my config file seems different to theirs though.

here is my config.txt file before making any changes

@acoustic python When posting configs or logs, please surround with code fences (```) so that Discord formats them correctly. Example:

For anyone coming across this thread looking for a fix. this is my full guide to steps to fix

Step 1: Edit the cmdline.txt file

Open the Raspberry Pi boot configuration file

sudo nano /boot/firmware/cmdline.txt

This opens the file in the nano editor for editing

Step 2: Add boot text rotation

Added the following parameter to rotate the boot text 180 degrees

fbcon=rotate:2

Saved the file and exited the editor (Ctrl+O, Enter, Ctrl+X)

Step 3: Create X11 monitor configuration

Create the X11 configuration file for your display

sudo nano /usr/share/X11/xorg.conf.d/90-monitor.conf

This opens a new file in nano where you can define the display settings

Step 4: Fill the X11 configuration file

In 90-monitor.conf, pasted the following content to set display rotation and resolution:

Section "Monitor"
    Identifier "DSI-1"
    # This identifier should match the name of the connector printed by xrandr
    # For example: "DVI-I-1 connected primary" → Identifier "DVI-I-1"
    # Or: "Unknown19-1 connected primary" for some GPIO screens → Identifier "Unknown19"

    Option "Rotate" "inverted"
    # Valid rotation options are normal, inverted, left, right

    Option "PreferredMode" "800x480"
    # Set the preferred resolution if needed

EndSection

Saved the file and exited the editor (Ctrl+O, Enter, Ctrl+X)

Step 5: Fix touchscreen orientation

Create a udev rules file to correct the touch input orientation

sudo nano /etc/udev/rules.d/51-touchscreen.rules

This opens a new file in nano

In the file, pasted the following content:

ACTION=="add", ATTRS{name}=="10-0038 generic ft5x06 (00)", ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 -1 1 0 0 1"

think this had to be on one line. so be careful

Saved the file and exited the editor (Ctrl+O, Enter, Ctrl+X)

Just wanted to say thanks @acoustic python came acrross this and it fixed my issue.
Updating the cmdline.txt did fix my boot text, but actually stopped the rest of the system from booting for some reason. But I really dont care if the boot text is upside so I'm leaving it as is, rest of it worked.

Thanks!
