Portenta H7: Failed to get snapshot

Help
#1

Question/Issue:
Hello, the board Arduino Portenta H7 (M7 core) with VisionShield can be integrated as a device in an Edge project, but you can not access the camera. Every time the error message is displayed:
[SER] Snapshot stream error: ERR: Failed to retrieve snapshot (-1).
And the board keeps going offline with the error message:
Error: Timeout when waiting for snapshot to be started or idle.

I had already uninstalled Python 3.10.4. and installed 3.9.7. but without improvement.
Thanks in advance

Hello @joe_bsz ,

What is the size of the image you are trying to capture?
Could you try with a smaller one?

If this still does not work, can you try to remove the shield and place it again?

Regards,

Louis

Hello @joe_bsz,

Could you share your project ID and which vision shield are you using?
I also suspect an issue with the board here. Could you try to use OpenMV IDE and see if you can get an image to make sure your vision shield works?

Best,

Louis

I have a Portenta H7 FOMO model running with 96x96 images.

The USB cable may be bad since the connection seems to be flaky.
