Hi, I have a OpenMV H7 camera. After I updated the firmware to 4.0.2 in the OpenMV IDE it stopped working with my Raspberry pi 4B. I used the pyopenmv_fb.py to display the frame buffer and the picture almost freezes. Before it was OK. Now the FPS is like 0.25. The same happens when I launch any example in the OpenMV IDE. Please let me know what I can do to fix it. I also tried to launch an example in Windows version of OpenMV IDE on another computer and it works fine.
Can you try the latest firmware? Release v4.1.0 · openmv/openmv · GitHub
Use Tools-Run Bootloader to run the OPENMV4/firmware.bin file.
Finally, the firmware definitely works for the camera. If your camera got bricked then the issue is related to something else.
Hi, It took me some time to get a new MicroSD card to install a clean Raspbian to make sure that none of the software in my Raspberry Pi is influencing proper function of the camera. The only application that I installed is OpenMV IDE. The problem, however, lasts. I have a low FPS in OpenMV IDE and when I use the pyopenmv_fb.py script. If I use RPC streaming script it works fine. Last time I forgot to mention that the firmware update to 4.0.2 didn’t go well. I had a white flashing LED afterwords. I used OpenMV to update to 4.1.0 as recomended and it went well. The camera LED was flashing blue after the update as expected. Now OpenMV IDE prompted me to update the firmware to 4.1.1 which I did and the LED was also flashing blue after the update.
