I am using a Raspberry Pi 4 Model B and when I installed the support packages I did it for this particular version.On the one hand, Matlab/Simulink always detects a Raspberry Pi 2 Model B (e.g. when I type raspi() in the Command Window). On the other hand, Raspberry Pi Resource Monitor displays a Pi with '2GB Ram and the ARMv7 Processor rev 3(v7) with 4 cores @ 1500MHz'. These specifications are correct for the RPI 4 Model B. Basically the RPI works, but I don't know why the wrong version is detected.

Same here. Does not detect my i2c bus too. This question has been up for months why has no staff at Mathworks answered it?

Same here. I am using a Raspberry Pi Compute Module 4 ( RPI OS is Bullseye) and Matlab2023B. Matlab detects BoardName: 'Raspberry Pi 2 Model B'

Hi Nicolas,
I understand that you wish to use a “RPI 4 Model B” board in MATLAB and have already installed support packages for the same and yet your MATLAB detects the device with an incorrect version.
Follow the pointers given below to resolve the issue -
  1. Verify the compatibility of your “Raspberry Pi 4 Model B” with your MATLAB version using the following documentation https://in.mathworks.com/hardware-support/raspberry-pi-matlab.html.
  2. Check and install available updates (if any) for Raspberry Pi support packages in the MATLAB Add-Ons Manager.
  3. Check and install Raspberry Pi firmware updates (if any) by running the following command on your board. Reboot your board for changes to take effect and connect to MATLAB. "sudo rpi-update"
  4. Establish a fresh connection with the board as per the below syntax, more on this in the following documentation https://in.mathworks.com/help/supportpkg/raspberrypiio/ref/raspi.html#d124e241
mypi = raspi(ipaddress,username,password);
If none of these step work, contact MathWorks Support for further assistance and more specific guidance based on your setup.
Regards,
Vinayak Luha
