Retropie doesnt boot with changed config

gilllig

Hello.
I have an raspberry pi4 B (4gb-ram), speaker expansion board and 3.5inch LCD Display (mpi3508).
I installed retropie according to some guide and replaced config in the /boot/config.txt. Im trying to rotate screen 180 degrees, bit there is an issue.
When I uncomment (add) line "dtoverlay=vc4-kms-v3d" the retropie boots, games boots, but the image is upside down. Seems settings in the config.txt doesnt work.
When I comment (delete) this line, image on the screen rotated as I need, but retropie doesnt boots - after all loading screens console starts only, with error: "Error creating SDL window! Could not initialize EGL. Renderer failed to intialize! Window failed to intialize!"
Can you help me please with this issue? I just want to rotate the screen.

This is config I've downloaded from some guide:

If you're using a recent RaspiOS, then the display_rotate parameters don't work anymore - rotation is either handled by the display's overlay (ads7846 in this case) or handled by the desktop (which is not included nor supported by RetroPie).

Removing the vc4-kms-v3d is not supported on the Pi4 with a recent RaspiOs, so you don't have much choices other than running the desktop and rotating image from the desktop utility (not sure how it's called now).

If you use the RetroPie provided image - which is based on an older RaspiOS - , you may still be able to use the display_rotate parameter for a 180deg rotation.

@mitu
Yes, I have retropie version 4.8

than running the desktop and rotating image from the desktop utility (not sure how it's called now).

Do you mean desktop on the raspberry (raspbian OS)? If I'll rotate screen image in this raspbian , it rotates in the retropie too?

Do I have to install raspbian (or another OS) for this?

Hm, that's strange - is this installed from the RetroPie image ? It looks like a Buster but with 64bit kernel, which was never released - the 1st 64bit image for RaspiOS was after Buster.

Do you mean desktop on the raspberry (raspbian OS)? If I'll rotate screen image in this raspbian , it rotates in the retropie too?

Yes, install the - current - RaspiOS with Desktop image and rotate it from the desktop. RetroPIe should install and probably work like this - from the desktop - but it's not a configuration we suppport. You need to do a manual install for this - see https://retropie.org.uk/docs/Manual-Installation/.

Do I have to install raspbian (or another OS) for this?

Yes, see above.

I dont know what "buster" mean, but probably it is. I just downloaded "retropie-buster-4.8-rpi4_400 from this page https://retropie.org.uk/download/ - it is the recent OS version.
I'm confused, what does it mean? Is there way easier than "install raspberryOS, then install retropieOS on it"? Maybe can I download older retropie version or change some graphics config in the system or something else?
Sorry, I know not much about how linux works, so it is a little bit difficult to understand your posts))

Btw which raspOS version will fit for my problem? There are 64/32bit, lite/full, bookworm/bullseye, legacy (and so on) in the Raspberry Pi Imager.

buster is the codename for the RaspiOS operating system. The RetroPie (4.8) image you've downloaded doesn't contain a recent RaspiOS though, it contains the version of the OS available at the time the image was created - which is dated right now.
Your screenshot though shows a 64 bit kernel, which is not included in the RetroPie image - how did you install it ?

As I said, install the current RaspiOS with desktop - which is code named bookworm. It should be the recommended image offered by Raspi Imager, but you can also download it manually from https://www.raspberrypi.com/software/operating-systems/#raspberry-pi-os-64-bit and write it with RasPI Imager.

@mitu thank you I'll try it right now)

@mitu Ive installed raspOS and retropie, but now they dont even run)) After launching I see console and some text (smth like "debian gnu linux raspberry tt2, my ip, raspberry login:"). Do you know what to do with this?
I tried to choose emulationstation at the settings, I tried to add line "/usr/bin/emulationstation" in the /home/pi/.bashrc, but its not working...
I cant understand how to make autostart for raspOS or for retropie

In the console I can run retropie by comand emulationstation. But comand startx doesnt run raspOS desktop, last lines after running this command:
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
Couldn't get a file descriptor referring to the console.

What exactly does this mean - they're both not running ?

You're running in an unsupported configuration, as I mentioned in my previous post, so you should not use the normal RetroPie auto-start options from the menu.

If you have installed the RaspiOS with Desktop, then just use the default option to boot to the Desktop. You can start EmulationStation from a terminal by typing emulationstaton. If you wish to automatically start Emulationstation after the boot to desktop is done, then

create the $HOME/.config/autostart folder
add a .desktop file with the command to start the terminal and EmulationStation (lxterminal -e emulationstation).
