Yes, it looks reproducible, it's probably an overly aggressive compiler optimization flag. We'll test more to find a solution.

Will do. Thanks for looking into this. 😁

I tested this with a couple of version and although it crashes on the PI4, it doesn't crash on a RetroPie Pi3B installation (latest update). I don't have a PI Zero installed, so I can't test with that.
Which image did you use to test on Pi3B ? -
@mitu I'm running 4.5.15 on the Pi 4 and 0w. I stand corrected. The Pi 3 is running 4.5.2... just checked again and turns out it was a BIOS error on my part. 😞
I have double checked the 0w and it had the correct BIOS and gives the Illegal Instruction. I have no idea how I managed to get a bad BIOS file on one Pi but not the others.
-
I've tested a few more scenarios and it looks like an issue with the DynaRec (dynamic recompiler) - a feature that speeds up emulation taking advantage of the ARM CPU's specific instruction set. Compiling the core without this feature doesn't show the crash, but the emulation will be slower.
It looks like compiling the core with a newer GCC available in Raspbian Buster makes the DynaRec crash, but the same code compiled with the GCC available in Stretch produces correct code (core copied from a 3B install works on a Pi4 with Buster). Doesn't seem to be optimization related, but it's difficult to find a fix in RetroPie. -
So this is a gpsp problem and not a RetroPie issue? Does that mean that the issue would also be present in the non-libretro version?

Possibly, but that won't run on the Pi4 so I didn't test it.
-
@mitu gpsp (non-libretro) gives me a SegFault on the 0w when installed from binary. I'm compiling from source now to see if that makes a difference.
-
gpsp SegFaults even if compiled from source.

Hi,
I've got the same error on my Pi0. Is there any solution for now?
I'm looked forward to play some GBA games and setup retropie today and then this. -

Install another GBA emulator and use it instead - https://retropie.org.uk/docs/Game-Boy-Advance/.
-
Thank you, I installed the gpsp, but got a segmentation fault error.
lr-vba-next ist not available and lr-mgba ist starting, so the rom is ok, but very poor performance -
@masterjule I don't think gpsp will be fast enough on your system anyway. I will look into it when I have a chance but I think you need at least an rpi2 for GBA.
-
I also have started having this problem since I updated. Maybe a previous package version for lr-gpsp would work if there is one. I'll be looking into a workaround until an actual fix is found.

I know for a fact that before, it would run gba games at full speed. I tested it myself.
-
@TechieAndroid What system are you running ? From what I've tested, it's not the emulator version that's the problem, but the compiler used to produce the binary - the one distributed with Raspbian Buster.
-
I'm currently looking into this btw (to avoid duplicate efforts)
-
@mitu Pi 0 W with the latest version of RetroArch.

I see. So when I tried compiling it I ran out of memory on my Pi 0 W. Then I tried compiling it in Arch with
make TARGET=PI1and then I replaced the binary with the one in /opt/retropie/libretrocores/lr-gpsp/ however it didn't change anything either.So I've been looking over the GitHub page and the maintainer hasn't provided much detail for compilation on various hardware. Do you know what compilation flags I might try on my computer to make it work on the Pi? I was basically guessing earlier.
-
Compiling the code with the mentioned methods doesn't work in any way, you end up receiving "Illegal Instruction".
What I did to temporarily solve this problem is to use a previous build of the gpsp_libretro.so binary and just as expected, it works!
