Raspberry Pi 3 model b+ run on boot problem

Dear all

I get this error when I activate run on boot option in Simulink for Raspberry Pi 3 model b+ and I can't find anything related to this error on Google:

Cannot identify C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\realtime\targets\raspi\src\mwrunonboot.service. No such file or directory.

I don't find 'mwrunonboot.service' on my computer.

I got the same error on Raspbery Pi 3 model b when I activated run on boot for both Simulink and MATLAB support packages. As a workaround, I ended up modifying the /etc/rc.local file to run my code on boot. I hope someone else can anwser this question.

how did you edit your rc.loacl file to run on boot?

I got a same ploblem on raspberry pi 3.

according to my experience, looks like the new version matlab pi support pack lost some critical files

[fangfines]

I tried copy the last version (2019a) pi support pack to the new version, problem looks like solved

[fangfines]

i copied "+pil" folder and "mwrunonboot.service" under pi supportpackages from 2019a to 2019b, seemed worked.

I'm getting the same error, very frustrating. I have tried to install 2019a to get the mwrunonboot.service in the support packages folder (/home/USERNAME/Documents/MATLAB/SupportPackages/R2019a/toolbox/realtime/targets/raspi/src/) No file called mwrunonboot.service is to be found. I do see the rc.local

Can someone please share with me that 'mwrunonboot.service' file? If not, can you at least give me a hint as to the function or the contents of such file so I could try to emulate it?

Thanks in advance,

sean

i also tried a lot with several times...

maybe i mistaked it, if i was right, i remember i tried both 2018b and 2019a, maybe i copied "mwrunonboot.service" from 2018b (which is my first try to solve the problem), and "+pil" folder from 2019a (then all worked).

and i suggust you check you also install the RPi support pack for all the matlab versions, before you try to find "mwrunonboot.service" and "+pil".

now i have:

mwrunonboot.service @

C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\target\supportpackages\raspberrypi\src

+pil (a folder with files)@

C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\target\supportpackages\raspberrypi\+codertarget\+raspi

C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\realtime\targets\raspi\+codertarget\+raspi

btw, i use EVERYTHING to locate and compare the difference of files between different matlab versions', which i find quite handy

Copying the file worked for me.

This is the content of mwrunonboot.service:

[Unit]

Description=Simulink Run on boot

After=multi-user.target

[Service]

Type=idle

RemainAfterExit=yes

ExecStart=/usr/local/bin/MW_runSimulinkModel

[Install]

WantedBy=multi-user.target

[Sean O'Connell]

Thanks a lot! I will give this a try once I go back to work after coronavirus blows over.

Luckily now Matlab 2020a supports the RPi4, so I will probably give that a try for my application as well. Hopefully they remembered to include this mwrunonboot.service file this time around haha

Hello,

I had same problem. In my case the file mwrunonboot.service was missing in directory: C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\realtime\targets\raspi\src, so I add it there.

I took the lines from answer above just in a text file and named this than: mwrunonboot.service

und hier noch mal auf deutsch:

hatte das gleiche Problem. Also habe ich mir eine Datei mit dem Inhalt aus vorheriger Antwort erstellt:

[Unit]

Description=Simulink Run on boot

After=multi-user.target

[Service]

Type=idle

RemainAfterExit=yes

ExecStart=/usr/local/bin/MW_runSimulinkModel

[Install]

WantedBy=multi-user.target

wie gesagt die Zeilen einfach in Textdatei kopieren und unter dem Namen mwrunonboot.service abspeichern und in den Pfad:

C:\ProgramData\MATLAB\SupportPackages\R2019b\toolbox\realtime\targets\raspi\src speichern.

Hier noch ein link wie man das Simulinkmodell einstellen muss, damit überhaupt eine ausführbare Datei erzeugt wird.

In meiner Anwendung hat das so funktioniert. Viel Erfolg
