Question/Issue:
Sampling Failed. Received snapshot is not a RAW or JPEG image. For RAW expected 76800 or 230400 values, but got 12.
It seems that at least two others have posted about this with no solid answers. Cannot proceed with project without having the H7 with Vision Shield camera working.
Problem happens on both Edge Impulse and Arduino ML Tools.
Context/Use case:
When trying to acquire data within Edge Impulse.
Steps Taken:
- Followed all instructions, step by step from EI documentation at: Arduino Portenta H7 | Edge Impulse Documentation
- Tried to collect data, received error message.
Expected Outcome:
Expected the camera to capture images and/or video.
Actual Outcome:
Entering snapshot stream mode…
