      @mitu said in Odroid XU4 SDL Problem Emulationstation:

      Re-install the libsdl2-dev and libsdl2-2.0-0 packages with their version from the Ubuntu repositories and then re-compile EmulationStation. Make sure your user is in the input, video and render groups and try to start EmulationStation. If that doesn't work, then use a minimal desktop environment to run the front-end.

      User is only in the input and video groups. No render listed with the groups command.

      Just added that group and restarted the system. ES still crashes. I will troubleshoot again in the morning. G'night.

        Would compiling ES with debugging symbols embedded help? If so, how would I make sure those are enabled?

        I am free now, so going to try your most recent suggestion.

          There is no retropie.cfg file in that location. I opened RetroArch.cfg, but couldn't find the string in question.

          I have removed all Retropie packages, and am recompiling now to see if I missed something.

            You can create the file and add own_sdl2=0 in it, so RetroPie-Setup will use the distro's SDL packages instead of trying to build its own.

              @mitu Well, I shelved the project for a good 15 days. Back at it again today. Tried your latest idea/suggestion, and...

              It worked!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

              Now facing a ES Welcome screen!!!

              Halleluiah!!!

              Thanks for all of your help and support in this! Couldn't have done it without you.

              (I kind of wish I had tried it 2 weeks ago ;)

                At first, I was excited! Until I tried to actually play a game...

                RetroArch started core dumping upon launch. I never did get it to work.

                I found and extracted the core dump, and ran a backtrace:

                  @aaronouthier Are you running from a desktop (X11) session ? The backtrace is not very useful, since the crash seems to happen outside of RetroArch, in the X11 libraries. I'm afraid that without a similar device (which I don't have) I can't be of any more help.

                    @mitu Not running from a desktop session. I don't even know if/how I can. There doesn't appear to be a Window Manager installed. I don't know if enough pieces are available to run a full X11 environment.

                    I did check the libraries listed, and both are symlinks, as follows:

                    lrwxrwxrwx 1 root root 15 Oct  2  2023 /lib/arm-linux-gnueabihf/libX11.so.6 -> libX11.so.6.4.0

                    /lib/arm-linux-gnueabihf/libGLESv2.so -> /usr/lib/arm-linux-gnueabihf/mali-egl/libmali.so

                    The 2nd of those seems a bit bizarre? That shared Library points to a library with a different name. Is that expected/normal?

                      Yes, it's not bizarre. Try installing a desktop environment, start a fullscren xterm and run emulationstation from it. See if you get the same crash with RetroArch or other emulators.

                        I opened an xterm, and from there ran emulationstation, but it gives me a black screen, no image appears. I am getting a signal to my TV though.

                        When I kill the emulationstation process, it goes back to X11 desktop with the xterm.

                        I am including the latest contents of es_log.txt:

                          Seem to be having issues with GL now?

                          I recently moved the board to a 4k TV however, so I can try editing config.ini to force a more reasonable resolution.

                            It seems that the distro-released SDL2 binary doesn't have support for the built-in Mali GPU on this board.

                            Revered back to RetroPie's source install. Now-Recompiling Core and Main packages.

                              Wiped the Install for a fresh 22.04 LTS. Following the docs very closely but will add the __platform var this time to the initial retropie-setup command.
