"matlab-rpi-setup" command returns "Illegal instruction" for Matlab Online Setup

I already set up my raspberry with package manager instructions from Raspberry Package support and are able to control ir from Matlab.

Now, I am following this guide https://www.mathworks.com/help/supportpkg/raspberrypiio/ug/connect-to-raspberry-pi-hardware-board-in-matlab-online.html to try to connect from Matlab Online

So, the problem is that when i run sudo matlab-rpi-setup I get: Illegal instruction.

Here is the log for the matlab-rpi installation:

Worth mentioning that I am using a Raspberry Pi Zero W.

Hi @Fabian Pichardo,

Are you working on 32-bit 0r 64-bit bullseye operating system?

Please note that in MATLAB Online, only 32-bit Bullseye is supported.

[Fabian Pichardo]

Hi @Prasanth Sunkara,

If I recall correctly, it was 32 bit but let me check again.

Thanks for your response

Hi Fabian,

Based on my understanding of the issue, it seems that you are attempting to connect to a “Raspberry Pi Zero W” Model using the “MATLAB Online Setup” and “Raspberry Pi Support Package”.

However, I regret to inform you that the “Raspberry Pi Zero W” is currently not supported by the package, which is why you encountered the "Illegal instruction" error.

Please note that the “Raspberry Pi Support” package in MATLAB Online is compatible with Raspberry Pi Zero 2 W, Pi 2 B, Pi 3 B, Pi 3 B+, Pi 4 B, and Pi Compute Module 4. Therefore, I would suggest considering an upgrade to one of these supported models. Alternatively, upgrading to MATLAB R2018a or a later version would also enable you to use the Raspberry Pi Zero W model.

For more detailed information regarding the supported Raspberry Pi models, I recommend referring to the following page: Raspberry Pi Support from MATLAB - Hardware Support - MATLAB & Simulink (mathworks.com).

I hope that the provided information will assist you in resolving the issue.

Thanks,

Sachin.

Hi Sachin,

Thank you very much for the information, I will try with either Pi 3B or Pi 4B.

Best regards

[Fabian Pichardo]

Hi Sachin,

Trying with Raspberry Pi 3B gave me this error after I ran "rpi = raspi"

Cannot open the device file for LED trigger source.

I also tried with this constructor: raspi(ipaddress,username,password)

The complete output is this:

### Updating Raspberry Pi I/O server...

### Connecting to board...

### Connected to 192.168.0.104...

### Installing nanomsg Library (this might take a while)...

### Creating server folder...

### Transferring source files...

### Building MATLAB I/O server...

### Launching MATLAB I/O server...

Cannot open the device file for LED trigger source.

Worth mentioning that i am using Matlab 2022b

@Prasanth Sunkara FYI

[Fabian Pichardo]

So, this issue seems to be solved here: https://www.mathworks.com/matlabcentral/answers/1946623-error-in-opening-matlab-device-file-for-led-trigger-source

so I had to install a specific version of the OS:

http://downloads.raspberrypi.org/raspios_armhf/images/raspios_armhf-2022-09-26/

Now I am dealing with the two-step verification procees to log in with sudo matlab-rpi-setup.

There is a troubleshoot page but even with that info I cannot make it work. Will continue tomorrow.

@Fabian Pichardo,

If you are using R2022b, as you have rightly found that, please use the older image.

R2023a is comaptible with the latest OS image (as of the date of this comment).

If you are facing issue with matlab-rpi-setup, I would suggest once try disabling two-step verification on your MATLAB Central account and see if it helps.
