How to fix BeagleBone Black Service File Autostart Script Error, status=203/EXEC

GoogleGroups
1

I want my BeagleBone machine to automatically start a script called server.js. It includes BoneScript (BeagleBone’s unique function) and many functions including reading voltage and ampere from other machines.

I used this tutorial Executing a script on startup using BeagleBone Black

It kept showing status=203/EXEC error.

I tried the same tutorial for simple programs without Bonescript and Functions. Indeed, simple sending and receiving scripts are working without any issue.

How can I remove the error? I think it happens from importing BeagleScript and Functions. I’m not familiar with Linux environment.

Can anyone help to solve the issue?

Thanks,

Hi, Robert. Thanks for quick reply.

Hi, Robert. Thanks for quick reply.
Indeed, after changing to ExecStart=/var/lib/cloud9/Projects/scriptname.sh

ExecStart=/var/lib/cloud9/Projects/server.js <-- maybe ?

Looks like: NODE_PATH=/usr/lib/node_modules is not set..

Hi, RobertCNelson.
Thanks for your answer.

I added this line in service file
Environment=NODE_PATH=/usr/lib/node_modules

[Unit]
After=network-online.target
[Service]
Type=simple
Environment=NODE_PATH=/usr/lib/node_modules
ExecStart=/usr/bin/scriptname.sh
[Install]
WantedBy=multi-user.target

But it shows this error.

add the export inside your script file...

#!/bin/bash
cd /var/lib/cloud9/Projects
node server.js

Hi, Robert.

I tried to put these into code one-by-one.
Do you know why it still shows error?

export NODE_PATH=’/usr/lib/node_modules’
export NODE_PATH=/usr/lib/node_modules
export NODE_PATH=/usr/lib/node_modules:$NODE_PATH
