Hi - after fixing the touch screen orientation, touch input is not not rotated to match the display. Can you assist? Thanks!

[iGridAU]

touch screen input not matching screen rotation is only broken on Raspberry Pi OS 32 bit. 64 bit works without issue.

Hello, thank you for feedback! here is the solution we provide for you:

1. reboot you system and using the ssh to enter the address of " /etc/X11/xorg.conf.d/", and make a file named 50-goodix-map.conf
2. copy and paste the content below(we will offer you a screenshot):
   Section "InputClass"
       Identifier "Goodix Capacitive TouchScreen Setting"
       MatchProduct "Goodix Capacitive TouchScreen"
       Option "CalibrationMatrix" "1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000"
   EndSection
3. save and check the file is all right by: vim /etc/X11/xorg.conf.d/50-goodix-map.conf
4. open the terminal and paste the query: systemctl restart lightdm
5. reboot and check if the screen and touch

Note: After you add " echo arm_64bit=0 | sudo tee -a /boot/config.txt" you then need to reboot and then proceed with installing the drivers.

I have installed the OS on reTerminal DM and followed all steps of installation and drivers updates. The LCD works well and touch orientation, too. If I connect an external mouse via a USB port, that works ok. The only problem when I remotely access the pi via VNC the mouse orientation via the VNC is 90 deg oriented and so difficult to go anywhere. Please help.

Adding a note here -- I was able to follow https://wiki.seeedstudio.com/reTerminal-FAQ/#q12-troubleshooting-touch-screen-inaccuracy after installing raspbian 64 bit and this fixed my touch screen issues. 👍

Are there any instructions for booting with NVME SSD? Have cloned os from eMMC, updated bootloader to latest version, set BOOT_ORDER=0xf21546 (Try NVMe PCIe first, followed by, USB PCIe, USB SoC XHCI, SD/eMMC then network) and it says failed to open device 'nvme', and proceeds to boot from eMMC. The drive I'm using is (Seeed Studio SSD).

Much appreciated.

Could you update your eeprom follow this link, and then try reboot again.

[cgjgh]

Are these instructions specific to RPi 5, as the reTerminal DM uses RPi Compute Module 4?

[LJ-Hao]

It will work on both RPI5 and RPI Compute Module 4.

Just installing a 32bit OS and after the line

echo arm_64bit=0 | sudo tee -a /boot/config.txt

I had to do sudo reboot before installing the drivers.
Otherwise the driver install failed.

Not sure if that's specific to me but, if not, might be worth updating the Wiki.
