Retropie 4.x on Odroid C2

detron

if we get RetroPie working on the C2, I see myself buying more C2s those things are fast!

@detron it will never be supported to the level of the rpi, but it will be source installable. I have a branch, doing some more fixing and I will do PR for testing..

WIP is here - https://github.com/joolswills/RetroPie-Setup/tree/odroid_c2

I know it will not be as well supported as the Raspberry Pi, and I would not expect anything else, I would be happy with any support. thank you very much for your effort (and others involved)

@BuZz
Thank You.
I'm downloading it.

--- EDIT ---

I started with a new installation.
retroarch doesn't finish the build process, I have an error patching glsym_es2.h:
retroarch patch 03_glsym_types.diff failed to apply

emulationstation ok
lr-beetle-ngp ok
lr-beetle-pce-fast ok
lr-beetle-supergrafx ok

lr-snes9x2010 ok

--- EDIT ---

The source code of retroarch has changed and the patch is no longer needed.

Update.

lr-bluemsx ok
lr-mame2003 ok
lr-nestopia ok
lr-stella ok

The autostart script doesn't work.
The system waits for the login. After a successfull login es starts automatically.

I almost find it funny that just last night I decided to see if I could get retropie running on my c2 and then I find this after I had already run the retropie script. Looks like your changes were already merged in though (probably why everything build successfully). FYI I had to run "sudo MAKEFLAGS="-j1" ./retropie_setup.sh" to build emulation station though.

I'm working with the minimal install though so it just fails with an error about mali not working or something (not in front of it ATM so I can't see post the actual message) . I know it's because I need to install lightdm though so I guess that's next.

Thanks for your work on this!

I meant when I try to start emulationstation (that wasn't clear)

During the build, the script has also built and installed libsdl mali-2.04?
Which libsdl2 packages are installed? You should have:
odroid@odroid64:~$ dpkg --list | grep sdl2
ii  libsdl2-2.0-0:arm64                   2.0.4+4mali                                   arm64        Simple DirectMedia Layer
hi  libsdl2-dev:arm64                     2.0.4+4mali                                   arm64        Simple DirectMedia Layer development files
from this source:
https://github.com/RetroPie/SDL-mirror/tree/mali-2.0.4
and not the original ones of ubuntu.

Hey roleo I'm having the same issue as the above poster and when I run the DPKG command as you have I get the same results as you do. I'm a Linux Noob so I'm not sure what else to do, but I did click on that link and downloaded a zip file called SDL-mirror-mali-2.0.4

Any help from there would be appreciated

@Bahn-Yuki
You do not need to download and build manually libsdl.
The script does it for you when you build retroarch and/or emulationstation.
But if you have the 2.0.4+4mali version like me, it's ok.

Bahn Yuki

I wonder what the issue is then. Out of curiousity, what resolution are you using? I'm using the 2160p:420 mode. It works fine in MATE, but could that be a problem for Emulationstation or KODI? KODI won't run either.

roleo

@Bahn-Yuki
What is the exact message error?
I'm using 1080p60 and I didn't try Kodi.

Bahn Yuki

@roleo
lvl0: Error creating SDL window!
mali-fbdev: Can't create EGL window surface
lvl0: Renderer failed to initialize!
lvl0: Window failed to initialize!

BuZz

@Bahn-Yuki if you are having an issue on the odroid-c2 I will need some detailed information. How did you install retropie. Are you running from console (After exiting the desktop etc).

Yes, this is the error I was getting. I had installed RetroPie using just

git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git
sudo MAKEFLAGS="-j1" ./retropie_setup.sh

on Ubuntu 16.04 LTS x64 Minimal and after the install the above error is the result when I try to start EmulationStation. Obviously with the Minimal install I don't even have a desktop, just the console. I think the problem is because there is no window manager installed either (?) but I haven't had time to go back and try to fix this yet

BuZz

@ElementZero It doesn't run from the desktop but from console - no X/window manager needed.

I have to say how super excited I am to see development on the C2. I love this board and I LOVE retroPie.

I've read several articles but all are dated, and ultimately people just gave up.

Crossing fingers on this one!

What base image are you guys using?

BuZz

@DavisDS85 I did initial development/testing on the hardkernel Ubuntu 16.04 image (which is aarch64 so many arm optimisations are lost). I will be looking at supporting a 32bit base also.

Oh ok - the error message had led me to believe it might have been the window manager but like I said I didn't have a chance to look into it yet. Well let me know if you need me to try something then - would there be a log or a way to debug more info from the error message?

BuZz

@ElementZero I would need a complete install log and errors (you said you are getting the same error as above, but I would prefer you copy and paste your exact error should there be a slight difference) - make sure you are not running from the desktop.

Also if you did anything else regarding installing 3rd party SDL2 libraries etc.
