Retropie 4.x on Odroid C2
-
@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.

@BuZz said in Retropie 4.x on Odroid C2:
@ElementZero It doesn't run from the desktop but from console - no X/window manager needed.
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?
-
@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.
-
So far, in your experience, is there any significant performance gains?
I was hoping to leverage the twice as much ram on game processing, but I've read some conflicting reports that the performance isn't as much as you'd think due to the GPU?
-
@DavisDS85 the extra ram isn't going to help with performance. some emulators are still not supported on aarch64/mali. I wouldn't rush out to get an Odroid-c2 just for RetroPie.
-
Too late.. I got over-zelous I guess. Made one of these into a portable webserver and it bench-marked amazing..
Next chance I had, I got another one. Problem is, I gave away my Pi2 for Christmas because I "just knew" this would work. Now I'm stuck with about $150 all in on a C2 with a 64GB Emmc (4 times the write speed). Just hoping I can make it work.
-
@roleo just tested on a clean minimal Ubuntu 16.04 image and autostart worked fine (ES was started on boot). If you are having trouble I will need some help to reproduce it (step by step from a fresh image etc).

I'm wondering - all I had basically done was loaded the minimal then do an apt-get update && apt-get upgrade and then installed retropie using the script and then I had the errors loading ES. I had some issues with apt-get upgrade though (and this morning I tried it and it breaks the boot partition). After reading on the forum it looks like there is some problems with the build of the minimal so I'm actually trying the mate now.
Anyways just curious if in your build where ES lauched fine did you run the apt-get upgrade first? Maybe some file is breaking there...
-
@ElementZero I didn't update first. I just created an
odroiduser on the minimal image, and added the user to the video/sudo/input groups - I then used that user to install retropie-setup. -
ok - yeah that's basically exactly what I had done the first time except I did the upgrade first. Let me try on mine without doing the upgrade and see if it just works, if so then it would seem the upgrade does something funky (which wouldn't be surprising seeing the errors during upgrade and other forum posts about it).
First though I'm going to finish this install w/ the mate image and see if that runs fine. Apparently there is no problem with doing the upgrade/dist-upgrade with the mate image and it does not give the depmod errors about the kernel version.
-
@BuZz
Ok, I will try again tomorrow. -
@ElementZero Unfortunately I had to put this on hold since my HDMI port apparently broke.
I can say that the minimal image IS broken if you do apt-get but apparently it's caused by u-boot being bad so if you hold that back then the upgrade is just fine.
-
@BuZz
I tried with a minimal image and autostart works properly.
Thank you.
But I had the same problem with EmulationStation as ElementZero: I changed the flag from -j4 to -j2 to complete the build process. -
@roleo Thanks. I will lower it to j2 by default

@BuZz Dear BuZz, I have just testted the trunk (61085b9) by
git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git
and it uses SDL 2.0.5. This version with Mali failed like following:

cc1: some warnings being treated as errors
.Looks like Mali part uses C99> syntax. You may want to fix it.
Best,
Nakata Maho -
@maho this should be resolved now.
-
@BuZz thanks for your fastest commit. I veerified that SDL2+Mali is no longer broken.
Best,

Looks like add some flags for 64bit support to build.

following patch will fix build of lr-mame2010 on ODROID-C2 (apparently you want a cleaner patch, though. sorry).

@maho please use a code block and format your post.
Thanks. There is a bunch of stuff that won't build still, but the most common modules should be OK. It should be considered a wip still.
