Part Number: AWR1443BOOST
Other Parts Discussed in Thread: TIDEP-01006

Dear Support team;

I would like to do the TIDEP-01006.

But, the following error occured on the Ubuntu Linux box when I done the "roslaunch turtlebot_bringup decrtiption.launch".

sugiyama@sugiyama-VirtualBox:~/catkin_ws$ roslaunch turtlebot_bringup description.launch
Traceback (most recent call last):
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslaunch/__init__.py", line 225, in main
    args = rlutil.resolve_launch_arguments(args)
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslaunch/rlutil.py", line 92, in resolve_launch_arguments
    resolved = roslib.packages.find_resource(args[0], args[1])
  File "/opt/ros/indigo/lib/python2.7/dist-packages/roslib/packages.py", line 495, in find_resource
    pkg_path = rospack.get_path(pkg)
  File "/usr/lib/python2.7/dist-packages/rospkg/rospack.py", line 201, in get_path
    self._update_location_cache()
  File "/usr/lib/python2.7/dist-packages/rospkg/rospack.py", line 184, in _update_location_cache
    list_by_path(self._manifest_name, path, cache)
  File "/usr/lib/python2.7/dist-packages/rospkg/rospack.py", line 67, in list_by_path
    root = ElementTree(None, os.path.join(d, PACKAGE_FILE))
  File "/usr/lib/python2.7/xml/etree/ElementTree.py", line 611, in __init__
    self.parse(file)
  File "<string>", line 38, in parse
ParseError: not well-formed (invalid token): line 1, column 0

Could you tell me how to repair?

Best Regards,

    Hi,

    It seems you didn't update the python settings.

    Please see section  3.2.1.2.2 AM572x EVM Running Processor SDK Linux of the user's guide.

    Dear Charles-san;

    I understood.

    But, this means on AM572xEVM.

    My log is on Ubuntu Linux box (PC).

    Do I need the same setting on PC (Ubuntu Linux box)?

    But there is no file of python3-config on my Ubuntu.

    Ubuntu version is 14.04 LTS.

    Could you tell me how do I do?

    Thats true. On the same page 15, there is a note to copy some files from the Sitara to the PC. Can you ensure you didn't skip that step?

    Also make sure you have ROS dependency including python installed. see section 1.7 of linked page .

    Dear Charles-san;

    Of course, I copied the following dirctries from the Sitara EVM to the PC.

    And, I wold like confirm.

    The URL you mentioned is Kinect ROS, but my ROS is Indigo.

    Should I install Indigo or Kinect?

    either one works,  you also need to install python dependency on Indigo. see 1.7 of linked doc

    Dear charles-san;

    I executed the "sudo apt-get install python-rosinstall".

    But I cannot find /usr/bin/python3-config file.

    Hi,

    is this a different error from the initial one? its unclear where the error is appearing at this point?

    the printout you share doesn't show any error.
