The discourse forum should be the place.

[beagleboard] eglinfo error: egl error 'EGL_BAD_ALLOC' (0x3003)

2021-06-09 Thread eb 
Hi, I am trying to get the NewHaven Parallel cape display 

 
working on the BeagleBone Black Wireless. I am using the Stretch ImgTec 
image.

The strange thing is that I got ANOTHER parallel cape display, from 4D 
System, AND another regular HDMI screen, working. eglinfo runs properly, 
and my Qt application using EGLFS works without a hitch. But on THIS 
display, I'm getting this error:

Creating Window surface..
PVR:(Error): WSEGL_CreateWindowDrawable: Couldn't set CRTC: Invalid 
argument [0, ]
Unable to create surface
egl error 'EGL_BAD_ALLOC' (0x3003)

What could it be about this particular display that's different from the 
others? I'm not sure if it helps, but I attached the output of eglinfo and 
"strace elginfo". Another interesting piece of info is that the kmscube 
application is running properly. So this is something specific to EGL.

Any help would be greatly appreciated!

Re: [beagleboard] Video device not found error.

2021-06-09 Thread jonnymo 
Things that would help to understand the issue are:

1. The output of the version.sh script:
  Ex:
sudo  /opt/scripts/tools/version.sh

2. Provide the Make/Model of USB camera used

3. What application is used when seeing the error?

4. Does the camera show in the 'dmesg' output and/or /var/log/syslog?

5. What troubleshooting steps have you taken thus far?


I think this would be a start in helping to understand your issue.

Cheers,

Jon
