I have the “Multi Camera Adapter Module V2.1”  sitting on a Raspberry Pi 4 with two Arducam OV7251  cameras connected to port A and B … but no chance to get them up and running.
Here is a screenshot showing the output from the init_camera.sh script:
Each of the cameras work on their own directly connected to the RPi (using MIPI_Camera SDK) but not in combination with the multi camera adapter.
Thanks for any help
According to  the v2.2 should also support the OV7251:
“…and the newest version V2.2 also supports other Arducam MIPI cameras like OV7251, OV9281, IMX135, IMX298, AR1820.”
If you want to use the ov7251 and multi adapter board, you should use our MIPI_Camera driver.
You can try this demo https://github.com/ArduCAM/MIPI_Camera/blob/master/RPI/python/multi_camera_board.py
Let me know if you need more help.
Yes, multi adapter board support those cameras you have mentioned. But the RPI’s driver does not support. So you should use our MIPI_Camera driver.
Thanks for that information. Can I use the MIPI_Camera driver in combination with the multi camera adapter?
