ODroid XU4 and RetroPie

krujak23

@BuZz Which RetroArch graphic (sdl2 vs gl) and audio (alsa vs sdl2) driver is recommended for the XU4?

Wow, wasn't going to start looking at this until this week, and I see a flurry of activity... thanks!

Before I saw all this I had tried the installation with the minimal image, and was having Mali driver issues. I did then install the mate version, (removed the lightdm) and was able to get retropie up and running fairly easily, it only took a few steps. Today/tomorrow I was going to start testing the different systems and see what worked and didn't. I did notice no Kodi option to install, no attract mode, and a lack of theme downloads, but none of which were a surprise.

I do have documentation of my steps, but I think I'll image my current setup, and then may try building the the minimal version before I go further. Is the general consensus that we should work off the minimal image?

BuZz

@krujak23 I've only tested gl.

BuZz

@Steve0 No Kodi as we only only include Kodi for RPI and PC. You can add a 3rd party odroid repo if there are any that have a working Kodi.

ES themes should be the same as on RPI.

Not all packages are available - but most of the main/optional ones are.

Since RetroPie on the Odroid XU3/4 runs from the framebuffer, it's easier to start with a minimal image, rather than removing/disabling the desktop stuff.

@BuZz you should check at applying my odroid patch to get kodi working on the framebuffer on odroid :
https://github.com/nadenislamarre/batocera.linux/blob/master/board/recalbox/xu4/patches/kodi/0011-kodi-mali.patch (this is the same for c2/xu4)

batocera.linux is based on buildroot, not openelec.

@nadenislamarre I have corrected my post. Sorry for this mistake ;)

BuZz

@nadenislamarre We don't package Kodi ourselves (I don't have the time). I believe there are some 3rd party repositories with Kodi for the odroid though.

@herb_fargus I have added the instructions for XU4 to the wiki. Please review.

BuZz

@krujak23 Thanks for doing that.

herb_fargus

@krujak23 I don't have an XU4 so I'll take your word for it. I'll check over the formatting when I get some free time and I'll update the docs accordingly. Thanks

I have a XU4 and would love to test this baby out!! Been waiting for the longest for a Retropie build to come out for XU4 nothing compares to it!

herb_fargus

@sketch2k278 there won't ever be an image for it, you'll have to use the guide on the wiki to build it yourself.

Also I can think of something better. My PC ;)

sketch2k278

@herb_fargus PC would always be better lol I just don't like sitting at a pc just to play games, it's a shame that it will not be an image for this, im not really good with linux sadly :-(

herb_fargus

@sketch2k278 I had never touched Linux before retropie. No time like the present! Otherwise you can use lakka. Basically the same thing

@krujak23 After the command sudo systemctl restart getty@tty1 i have a black screen and the Step 12 cant resolve.

krujak23

@cadsj I have changed the step no 10 from:

[Service] ExecStart= ExecStart=-/sbin/agetty -a odroid --noclear %I $TERM

to:

[Service] ExecStart= ExecStart=-/sbin/agetty -a NameOfYourChoice --noclear %I $TERM

Try now!

@krujak23 Problem solved with this change i suggest update the installation page and remove...

Finally, run bootini and reboot:

bootini
sudo reboot

run bootini doesn't work, i just reboot and continue the tutorial.

cadsj

In the end, i get these messages.

Error Initializing SDL:
mali-fbdev. Could not open framebuffer device
Renderer failed to initialize!
Window failed to initialize!

this is happen on boot, after finish the tutorial.

krujak23

@cadsj I have taken the "Finally, run bootini and reboot bootini sudo reboot..." from the C2 guide. You are welcome to edit the XU4 guide by yourself.

I did not have any problems running the RetroPie on my xu4. I will check the problems with mali-fbdev over the weekend...

@cadsj Which version of the minimal Ubuntu image did you install? I have worked withe XU3 version from 2016 (ubuntu-16.04-minimal-odroid-xu3-20160706) and I have seen that Hardkernel has uploaded few days a go a newer version (ubuntu-16.04.2-minimal-odroid-xu4-20170516).
