Hi i'm trying to use my raspberry and the camera to do data acquisition and control with matlab but after the connection to the raspberry, matlab is not connecting to the camera. it's for a project and without that i can't do anything.
This is the error i receive with this both lines :
i've tried each and the result was the same.
cam = cameraboard(mypi, 'Resolution', '1280x720');
cam = mypi.cameraboard;
Warning: Response size for request ID 0xF150 is expected as 4 but received as 0.

Hi @Wilson,
I have encountered a similar issue before, and I recommend using only the Raspberry Pi operating systems listed on the following page:
https://www.mathworks.com/help/releases/R2024a/matlab/supportpkg/install-support-for-raspberry-pi-hardware.html
From what I can gather from the comments is that you are using a 64-bit OS, but MATLAB R2024a only supports 32-bit operating systems. I suggest flashing your Raspberry Pi with a fresh 32-bit OS. Once you have installed the new OS, you can clean the existing MATLAB installation on your Raspberry Pi by running these commands in the terminal:
$ sudo pkill mwUnifiedSrvr
$ sudo rm -rf /opt/MATLAB
After this, you can proceed with creating a new "raspi" object and the "cameraboard" command should run fine. If you still encounter issues, I recommend contacting MathWorks Technical Support. You can create a support ticket using the following link:
https://supportcases.mathworks.com/mwsupport/s/casecreation?language=en_US&c__caseParameter=Get_help_using_products&s_tid=srl22_help
I hope this helps, thanks!
