OpenBOR 6xxx OpenBeta Testphase
-
Thanks again! I did all of this again on my pi3b+ and got a working configuration going with the Beta. I could not figure out how to map controller inputs, but I used xboxdrv as a workaround and it's running good on that system. So now I'll use the pi3b as a blueprint for what I should change on my zero. :) I want to make a guide on this to help others in our facebook group to set this up on theirs also, and it would also be very cool to explore how you did the oneliner, and see if I could make my own oneliner for them to use, or at least a build from source option (scriptmodule) like you did for pi3b.

@cyperghost Still trying to get this working with no success on the pi zero :( Are we sure that @julenvitoria was using Galina? Which scriptmodule do you think they used before overwriting the binaries? I was using
http://raw.githubusercontent.com/crcerror/OpenBOR-63xx-RetroPie-openbeta/master/scriptmodules/openbor-6xxx.shand so everything went into/opt/retropie/ports/openbor-6xxx/instead of/opt/retropie/ports/openborIf I try launching it via Emulation Station [OpenBOR - Module Selection Script] all I see in my /dev/shm/runcommand.log is:
Executing: pushd /opt/retropie/ports/openbor-6xxx; /opt/retropie/ports/openbor-6xxx/OpenBOR ""; popd /opt/retropie/ports/openbor-6xxx /home/pi/RetroPie/roms/ports /opt/retropie/supplementary/runcommand/runcommand.sh: line 1012: 6166 Illegal instruction /opt/retropie/ports/openbor-6xxx/OpenBOR "" /home/pi/RetroPie/roms/portsOn a successful launch from my pi3b+ I see this instead, so there is a difference here:
Executing: pushd /opt/retropie/ports/openbor-6xxx; /opt/retropie/ports/openbor-6xxx/OpenBOR "/home/pi/RetroPie/roms/ports/openbor/TMNT_RP_1_1_1.pak"; popd /opt/retropie/ports/openbor-6xxx ~Edit: Ok, I found a missing line that Pi3 had that zero didn't. I added it to the zero's emulator's config, and now the executed command looks the same for both, but the zero still gives the "illegal instruction".
The missing line was:openbor = "pushd /opt/retropie/ports/openbor; /opt/retropie/ports/openbor/OpenBOR; popd"If I try launching it from CLI [sudo ./OpenBOR] I see this:

Even fresh off the compiler, just doing ./OpenBOR
I thought maybe it was because I was sending video over GPIO pins (Retroflag Gpi case) so I tried taking it out of the case, removing the GPIO video settings, hooked up to TV with HDMI, still same "illegal instruction". Not sure what else I can try.Edit: Looks like this might be a problem with my particular retropie image. Another friend was able to compile and launch Anna on zero using a different image. So right now I'm also trying Anna and if that fails, it has to be my image.
Edit: Anna failed "illegal instruction" so this has to be a problem with my image, no doubt about it.
-
@SinisterSpatula Please rename or delete GL4ES.

I tried a fresh 4.4 image and got the same results. I'm really stuck and not understanding why I keep getting this
Illegal Instructionerror. Only thing I can think of is a problem with my OpenGL libraries, or the binary itself that is getting compiled is not compatible with pi zero? Or I'm still doing something else wrong.Edit: Just deleted libGL.so.1 tried ./OpenBOR and still illegal instruction.

@SinisterSpatula hmmm.... what is the result of
ldd OpenBOR?
I'm really just guessing now. I never compiled this on a RPi1/0illegal instruction is usually 99% caused by providing RPi incompatible packages
-
I think you're right, because I just followed the exact same steps on my Pi3 that I'm doing on my pi zero, and it worked perfectly, no error, brought up the BOR gui menu. So I must be compiling for pi3 still, somehow?

@SinisterSpatula sorry!
Posted wrong. It looks all fine!
@mitu Can you help here please? -
Sorry I'm sure this is a dumb question, but where or how do I get that installed or placed where needed? :) Still learning. Oh ok. Back to the drawing board I guess lol. I'm going to try a different image for the zero and see if I have better luck.
-
@SinisterSpatula I posted wrong! Sorry! I've tagged mitu. I think he can help
-
@SinisterSpatula Moment .... what image did you use? A preinstalled one?
-
@cyperghost Most recently I used a stock image: retropie-4.4-rpi1_zero.img which should be stock standard, nothing but enabling ssh, samba, I did a fake-hw-clock to stop the system file checks on every boot, I installed xboxdrv (I like to use that for gamepad remapping to keyboard keys. That's all I've done I'm pretty sure.
-
@SinisterSpatula Okay then wait for an answer from mitu. I think he can help
-
@cyperghost said in OpenBOR 6xxx OpenBeta Testphase:
@mitu Can you help here please?
I can try, but it looks like the problem is that the binary/some parts of it (gl4es ?) are compiled for a RPI3, while the PI0 has a different CPU, thus some optimized instructions in the binary will not work for it.
-
@mitu that's what it seems like to me too. What's weird though, is if you look in this thread starting here: https://retropie.org.uk/forum/post/191200 another member was able to compile this beta for the zero. They don't say what they did or how they did it though :(
-
@mitu No it's compiled by the scriptmodule and GL4ES is deleted. So it's ARM6 instructions. I've never compiled on Pi1/0 platforms and I don't have one available.
ldd looks okay
-
@cyperghost said in OpenBOR 6xxx OpenBeta Testphase:
No it's compiled by the scriptmodule and GL4ES is deleted
Ah, then it's not the CPU instructions mismatch.
-
@mitu Well, it could be... See I'm doing the scriptmodule first. But then I'm compiling again, and overwriting the binary with my own. I'll try just the scriptmodule alone, maybe that's the issue?
-
@SinisterSpatula Then the GL4ES is wrong. The scriptmodule uses a prepacked GL4ES made for RPi3 therefore I asked to delete this.
Maybe you can compile GL4ES on your platform.
Instructions are here
https://github.com/ptitSeb/gl4es -
@cyperghost Yeah, just to clarify, I was doing script module, then compiling my own openbor executable, and my own GLES4, and overwriting them both, into the folder of where the scriptmodule installed to. Is the script module able to change the compiling flags to the needed ones for zero? Or would I need to modify those before compiling?
-
@SinisterSpatula The scriptmodule has nothing to do with compiling flags. It's the patch itself.
Compiling flags are set to
CFLAGS += -marm -mcpu=cortex-a9 -mfpu=neon -mfloat-abi=hard -fomit-frame-pointer -ffast-math -O2
