Emulationstation crashed and Cannot allocate memory on pi4
-
Can you post the
dmesgoutput on pastebin.com ? Do you have anything configured on the start/stop runcommand scripts ? -
If you set the GPU mem too high, you'll never be able to boot that SD card again on a Pi 4 unless you reinstall an image OR boot the card on a Pi 3B and reset the GPU memory there. I did that to mine when I set it above 512mb.
-
@VictimRLSH I don't have gpu mem set at all. Also, the boot partition is accessible from a Windows computer if you need to make edits to your config.txt.
-
I cant seem to get it to reliably crash anymore. It has been stable all day though I havent changed anything. Will post a dmesg if it crashes again.
-
ES crashed again today (it has done it a few times since my last post but not reliably). It always seems to occur when ES is either loading or when Im launching a game. I was able to get the dmesg output this time.
-
There's no driver errors in the
dmesg, so it doesn't look like a kernel driver bug/error. Can you try reproducing with the stock theme or maybe uploading your modified theme somewhere so we can try and see if we get the error ?EDIT: Are you using the 'normal' EmulationStation install or the
emulationstation-devpackage ? -
@mitu I am using the standard/normal emulationstation install. I will switch to carbon for a bit and see what happens. I am using a modified version of the nostalgia theme https://github.com/supersquared/es-theme-nostalgic-neo
-
@quicksilver Seems like it was crashing more often before you changed the vram settings and disabled the screen saver. If that's correct, I would start lowering the vram setting in ES again and see if it reproduces more consistently.
Also, have you run emulationstation with the --debug option? That might help clarify what's happening. But it might stop crashing if you just raise vram to 512m (which should be reasonable if you have the 4g model).
-
So I'm thinking the crashing is related to the theme. I installed the same theme on my previously stable pi 3 now it is crashing occasionally. I don't know much about theming so I can't tell what is wrong here. Would someone be able to take a look at the link I posted above and see if anything glaring sticks out? I have also noticed that this theme takes much longer to boot up though I can't figure out why, all of the different art file sizes seem to be roughly the same size as other themes but other themes boot much faster.
-
I've installed the theme yesterday, after you posted the source, and briefly tested it, but didn't get any crash so far. I've left it active, trying to see if I get a crash.
To help debug this, you can run ES through a debugger and get a crash backtrace.- install
gdbwithsudo apt install gdb - exit EmulationStation and start a SSH session to your PI.
- run from the command line (via SSH)
gdb -q /opt/retropie/supplementary/emulationstation/emulationstation -ex runthis should start ES from the debugger
- try and reproduce the crash. When it crashes, you should get a message in the
gdbsession that it did so. Run fromgdbprompt
bt fullthen get the output and post it here.
- press
qto exit the debugger.
- install

@quicksilver Hm, seems we're getting somewhere, but since the output is truncated we don't see the calling site in the EmulationStation code. Do you remember what system was loaded when the crash occured ? I realized I might not have one of the systems from your install and that's why I couldn't - briefly - reproduce the crash.
-
@mitu In this particular instance I think it was PPSSPP, though it has crashed for me on multiple different systems. And the crash isnt reliably reproduced. A crash can sometimes occur on the first game I launch or I might have several crashes in a row or I might launch many games with no crashing.
-
Just for comparison of systems, can your run
find $HOME/RetroPie/roms/ -type d ! -empty -maxdepth 1and post the output on pastebin.com ? Just want to see what's the difference from my system list.

I also note that my gameslist view is set to video. I dont have any videos but its the only way for the marquee/wheel art to show up. Not sure if that matters but thought Id point it out.

I already have this setting. Thanks for the system list, I'll see if it has any impact on my installation.

I just got it to crash on the carbon theme. I just launched and then exited a PSP game a few times to cause the crash. The only other thing I can think of that would also suddenly make my pi 3 crash as well is that I am using some specific system artwork.xml files with skyscraper. For example, for PSP I have an artwork-psp.xml which corrects the image to the correct aspect ratio for when I generate my gameslist. I have done this for several other systems as well to make the aspect ratios correct for systems that werent 4:3. Could this cause an issue?
<?xml version="1.0" encoding="UTF-8"?> <!-- This is the default artwork.xml provided by Skyscraper. More examples can be found in '~/.skyscraper'. Be sure to check the full artwork documentation here: https://github.com/muldjord/skyscraper/blob/master/docs/ARTWORK.md --> <artwork> <output type="screenshot" width="320" height="180"> </output> <output type="marquee" resource="wheel"/> </artwork> -

Could this cause an issue?
I don't think so - the end result is still a
pngimage that EmulationStation loads,artwork.xmlis just a set of design instructions for Skyscraper of how to produce that image from the cached artwork, it doesn't influence how EmulationStation loads or displays the resulting image. -
@mitu Yea, I didnt think it should be a problem either except that is the only other thing that I changed on my pi 3 and now its crashing as well.
-
Still can't get a crash. Let's see how we can further progress.
- can you try with view mode set to 'detail' (i.e. no 'video') to see if the lack of marquees has any impact ?
- can you upload the
gamelist.xmland themediafolder (generated by Skyscraper) for your PSP system - temporarily - so I can have an identical gamelist/system for PSP ?
