View Full Version : Sample UDEV file for Stellaris Launchpad

January 5th, 2013, 06:40 PM

I'm trying to get my Stellaris Launchpad to work with the Energia IDE.
I'm told to upload programs and to run the serial port I've got to create a udev entry.

I'm relatively new to linux (although not Ubuntu) so could anyone please provide me with a sample udev file.

My Stellaris board's on port /dev/ttyACM0, VID=1cbe and PID=00fd.

As of now I'm using the attached udev file(text file).

It's as follows ->

# This file allows non-root access to TI stellaris launchpad
# See udev(7) for syntax.

Thanks in advance

Problem solved.

For those with the same or a similar problem. Here's the simple solution.

Step 1: Add your username to the "dialout" group. In terminal type,

sudo adduser <username> dialoutStep 2: Create a udev (eg: 61-stellpad.rules) file in the directory: /etc/udev/rules.d/
with the contents as,

SUBSYSTEM=="usb", ATTRS{idVendor}=="1cbe", ATTRS{idProduct}=="00fd", MODE="0666"
Step 3: Save, unplug and replug the Stellaris board. All done.

[Note]: The solution was provided by a fellow Stellaris Launchpad user - Bernard.
Works perfectly now.

Hello Nessler

Thanks for the post.
It helped me fix the same problem I ve had with my stellaris
on ubuntu.

However I used only the first

# This file allows non-root access to TI stellaris launchpad
# See udev(7) for syntax.
SUBSYSTEM=="usb",ATTRS{idVendor}=="1cbe",ATTRS{idP roduct}=="00fd",MODE="0666"
KERNEL=="ttyACM0",ATTRS{idVendor}=="1cbe",ATTRS{id Product}=="00fd",MODE="0666"

It did not work for me initially.

However after looking carefully i noticed this

SUBSYSTEM=="usb",ATTRS{idVendor}=="1cbe",ATTRS{idP roduct}=="00fd",MODE="0666"

The space between the P and r in "Product" made the udev rules ineffective.

Once, that was fixed then the original udev rule you posted works just fine.

Ditto with the "kernel" line too!!

Hi krish2487 (http://ubuntuforums.org/member.php?u=1140626),

Thanks for that.
I actually had copied it from an online post. It had never occurred to me before though.
