RGBCommander not working on RPi4

Main > Raspberry Pi & Dev Board

(1/2) > >>

StefanV:
Hello everyone,

I used RGBCommander on my RPI 3 without any problems.
After migrating to RPI 4 RGBCommander stopped working.
I tried to solve this problem but don't get any further.
I guess it is because RGBCommander is not recognizing the different emulators used in the RPI 4 Setup.

Attached the log files for the working and non working setup.
Processes for RPI 3 working:

In the non working rgbcmdd.log the following I guess important things are missing:

--- Code: ---...
16/12/20 15:17:43 [DEBUG] [rgbcmddMsgQueue] msg from rgbparse -> emu -> arcade -> rom -> 1942
...
16/12/20 15:17:49 [INFO] [execOutputHook] exec hook -> "/usr/sbin/rgbcommander/scripts/OnEmuStart.sh" 'arcade' '1942'
...
--- End code ---

I guess I need to add or adjust some configuration in the emulators section of the rgbcmdd.xml (attached) , but I am not able to figure out the correct config.

Any help is much apreciated.
CU, Stefan

Update:
I did some further investigation.
Using the same emulator on a RPI 3 proves a working RGBCommander:

--- Code: ---ps aux| grep 1942
pi 3305 0.0 0.0 1940 376 tty1 S+ 15:33 0:00 sh -c /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ arcade /home/pi/RetroPie/roms/arcade/1942.zip
pi 3306 1.0 0.2 8464 3700 tty1 S+ 15:33 0:00 bash /opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ arcade /home/pi/RetroPie/roms/arcade/1942.zip
pi 3953 22.2 8.5 328276 136340 tty1 SLl+ 15:33 0:04 /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fbalpha2012/fbalpha2012_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg /home/pi/RetroPie/roms/arcade/1942.zip --appendconfig /dev/shm/retroarch.cfg
--- End code ---

So it is not a matter of the used emulator but seems to be an issue with the RPI4.

Anyone here using the RGBCommander on RPI 4 with success?

Thanks, Stefan.

I use it for my U360 but I do not have any LED's. I guess I will have to check the log and see if it is loading correctly. I just changed from a 3 to the 4 so I have not done a lot of testing yet. I will try and let you know once I get to it.

That would be great!

While I've used RGBcommander in the past, i haven't used it on my Pi 4s...so I'm just dropping in to say: If you can't get it working, LEDSpicer is an option. I wrote up a pretty comprehensive guide to setting it up:

I don't have bad things to say about RGBcommander. I just had to stop using it because i wanted to integrate mode switching in my GGG 49-way joystick, which RGBcommander didn't support. There is a slack channel for support for LEDspicer if you try it and get stuck.
