Remote side unexpectedly closed network connection May I ask what I need to do to solve this problem? I have repeatedly installed the same error message several times. My device is PI4 and the system is 2023 02 21 raspios bulleteye arm64.img

Hi I installed the May 64bit RPiOS with Pi4B and LCD(C) then did: 1 sudo apt update 2 sudo apt-get full-upgrade -y 3 sudo reboot 8 git clone https://github.com/waveshare/LCD-show.git 9 cd LCD-show/ 10 chmod +x LCD35C-show 11 ./LCD35C-show 12 sudo apt update 13 sudo apt-get full-upgrade -y 14 sudo apt --fix-broken install

Both the LCD and touch driver worked fine Install messages are here: https://github.com/TobiasVanDyk/RaspberryPi-GPIO-Displays/blob/master/ili9486/pi4B-lcdC-2023/install2.txt

Hi @TobiasVanDyk Are you using Bookworm 2023-05-03 version?

[Toh-git]

which one of these ? please suggest. https://www.raspberrypi.com/software/operating-systems/#raspberry-pi-desktop

[TobiasVanDyk]

Ignore please

[TobiasVanDyk]

Hi Sorry I have not tried it yet with the new Oct bookworm

[TobiasVanDyk]

Hi Sorry I thought it was about the soundhat

I have not tried it yet with the new Oct bookworm

got it running on Pi 4B with kernel 6.1 on bullseye and bookworm (Raspberry PI OS 64-bit version) following [waveshare wiki instructions] (https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(C)#Install_the_touch_driver)
(example for C version)

also assuming x-org is used (and not wayland on bookworm)
do not mind calibration errors, on install
setup afterwards as @TobiasVanDyk mentioned:

14 sudo apt --fix-broken install

following must be run with root privilege:

./LCD35C-show

# now
sudo  ./LCD35C-show

then updating (or creating) /usr/share/X11/xorg.conf.d/99-fbdev.conf as mentioned here:
https://forums.raspberrypi.com/viewtopic.php?t=161512#p1048180

...
  # output to LCD screen
  Option "fbdev" "/dev/fb1"

  # or replace with this to output to HDMI instead
  Option "fbdev" "/dev/fb0"
...

@JimJ92120 Thank you, it worked perfectly for the A version on a Pi 4B with bookworm. The only thing I'm strungling with now is how to rotate the display. When I launch sudo ./LCD35-show 180 it inverts the touchscreen but not the actual display. I tried many things from X conf file, xrandr options, raspberry config.txt file. Nothing appears to be working. Any solution ?

[mymatenige]

Are you using X11 or Wayland? You may find that xrandr works with X11 but not Wayland.

[JimJ92120]

@tuxrinku maybe this? https://www.makeuseof.com/how-to-rotate-your-raspberry-pi-screen-without-moving-the-display/

the display_hdmi_rotate worked for me

[tuxrinku]

I tried everything mentioned in this article. Every orientation option is greyed out in the desktop screen option. When I try using xrandr it returns the following error xrandr: output default cannot use rotation "inverted" reflection "none". I tried config.txt options like display_rotate=2, lcd_rotate=2, display_lcd_rotate=2, display_hdmi_rotate=2. None of them worked. I guess it has something to do with fbdev since it was a workaround to make the lcd screen working on bookworm.

I'm using X11, the lcd screen wouldn't work on wayland apparently

Hello! I got this screen: i've been trying with different os, and testing with all ./LCD commands here... I can't make it work into my Raspberry Pi4b. Did some 1 succesfully set up this type of spi tftlcd in a RASPI4b? Helllllp!!

Hi Tobias! Thanks for the fast response, i've seen that, but cant find the way to make it work.. im in a fresh instalation...

this is what i get when i run ./fbcp-ili9341 but the screen stillls white.. (ofcourse the screen works, i've tested with some kedei's programs and on a raspi 1b with their custom image and the screen works.. but in my Pi4b doesn't.. really, I won't give up till it works (or i get bored of lying around xD). I'ld love to got my pi4 with this screen xd
