Matlab detects the wrong version of my Raspberry Pi

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 problem here on linux mint with matlab 2021a. my paspi 4b is detected as 'Raspberry Pi 2 ModelB'. no available sPI, I2C bus or webcams visible.

gpio acess works, but only pin 2-27 are visible. and the connected logitech brio is not visible.

any help?

I have the same problem with boardName under MATLAB 2021B and running burnbed image mathworks_raspbian_DL_R21.2.0.img on sdcard. The raspi output is

Port: 18734

BoardName: 'Raspberry Pi 2 Model B'

AvailableLEDs: {'led0'}

AvailableDigitalPins: [4,5,6,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]

AvailableSPIChannels: {'CE0','CE1'}

AvailableI2CBuses: {'i2c-1'}

AvailableWebcams: {'mmal service 16.1 (platform:bcm2835-v4l2-0)'}

I2CBusSpeed: 100000

AvailableCANInterfaces: {}

I have not tested yet if the wrong boarName is causing any performance issues post deploy in Rpi.

I am having the same issue. Can you update if you found out the reason for it or not?

[Nicolas TRAUN]

Sure, as soon as there is a solution I will update the post

I am also having the same issue. Has anybody found a solution for this?

[Dinis]

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

[Brian Kingstone]

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.
