Issues with O2L and Bela program

Knallberto

giuliomoro this error is because you have another copy of the program already running, possibly running on boot? Press stop after a reboot before starting the project.

I tried to press stop after reboot before starting the project. I get the same error.

made a new thread.

Do you have a program running on boot at all? Can you run evl ps -st in the console after you receive the above message and post the result here?

I don't think so.

giuliomoro Can you run evl ps -st in the console after you receive the above message and post the result here?

So you cannot run any Bela program at all? If you do systemctl stop O2L, can you then run a program?

giuliomoro So you cannot run any Bela program at all?

I just tested some PD example patches and a c++ example as well. The problem seems to be PD specific. I was able to build the c++ example.

giuliomoro If you do systemctl stop O2L, can you then run a program?

Yes, then I can run my PD patch as well.

OK thanks, I found the issue. Get the latest andrew branch again and try again. You should be able to run a pd program on the side now.

Knallberto

Thanks. I cannot see andrew anymore. Am I supposed to use pixelbone now? I tried this. But when I run O2L my LEDs are not doing anything.
