Rasbpberry Pi and MATLAB connection

Hello,

I am trying to connect MATLAB to Raspberry Pi. I wrote this code:

targetObj=targetHardware('Raspberry Pi');

deploy(targetObj,'CARPID');

r=raspi('10.0.0.121','vanderei','vande')

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

### Connecting to board...

### Connected to 10.0.0.121...

### Creating server folder...

### Transferring source files...

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

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

Error retrieving the board revision.

I could not find the reason of this error. Can you help me?

Thank you.

Hi ,

Please tell which version of the MATLAB you are using.

Also please tell which operating system of the raspberry pi you are using .

This can be known by executing the following command in the raspberry pi

$ cat /etc/os-release

Please tell whether you are using 32 bit OS or 64 bit OS by executing the following in the raspberry pi

$ uname -m

Are you able to create the raspberry pi object on the MATLAB.

Please answer all above questions so that we can help you better.

Thanks,

Hi,

Thank you for your reply.

I use MATLAB R2024a.

And the operating system of the raspberry pi that I am using is:

PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

NAME="Debian GNU/Linux"

VERSION_ID="12"

VERSION="12 (bookworm)"

VERSION_CODENAME=bookworm

ID=debian

HOME_URL="https://www.debian.org/"

SUPPORT_URL="https://www.debian.org/support"

BUG_REPORT_URL="https://bugs.debian.org/"

And I am using aarch64.

To create the raspberry pi object on the MATLAB, I use this command in MATLAB:

>> r=raspi('10.0.0.121','vanderei','vande')

but after run I have this error:

Error retrieving the board revision.

And the raspberry pi object cannot create on workspace in MATLAB.

Thanks.

Hi,

As of the R2024a release, the MATLAB Support Package for Raspberry Pi hardware is compatible only with the 32-bit versions of Buster and Bullseye operating systems.

The raspi object creation is failing because here the raspi object is created for bookworm 64 bit OS.

Thanks

Hi,

Thank you for yout answer.

I changed to 32-bit but I have problem yet.

The error changed. but I have errors yet to create raspi object in MATLAB.

and now this complex error:

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

### Connecting to board...

### Connected to 10.0.0.121...

### Creating server folder...

### Transferring source files...

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

[MathWorks MATLAB Hardware Team]

Could you kindly confirm if you've updated the Raspberry Pi with the 32-bit Bullseye OS? From the logs, it appears that the Raspberry Pi might have been updated with the 32-bit Bookworm instead. It's important to note that the MATLAB Support Package for Raspberry Pi is compatible only with the 32-bit versions of Buster or Bullseye OS.

To verify the current OS version on your Raspberry Pi, please execute the following command in the Raspberry Pi terminal:

$ cat /etc/os-release

If the output indicates "Bookworm", we kindly ask you to reimage your Raspberry Pi with a 32-bit version of either Buster or Bullseye OS.

Should your Raspberry Pi be running on Buster or Bullseye and you continue to encounter the issue you've mentioned, please do not hesitate to get in touch with our technical support team at: https://www.mathworks.com/support/contact_us.html

Thank you for your attention to this matter.

Warm regards,

The MATLAB Hardware Team

Thank you. It didn't work for three days, but it worked out after changing the operating system

Its dissappointing that matlab relies on a 32bit OS and the userland library, which is explicetly declared obsolete and with "DO NOT USE" in its github repository.

Same for wiringpi, which was nothing but a hobby project by an individual and has long been abandoned by that person. Pretty much everyone has moved to official linux drivers.
