Hey,


Sometime when I turn on my OP2, his Rx LED always ON when demo, and the system crash, need to reboot until Rx is OFF.

How can I solve this problem ?

I'll collect more information and return to you.


FYI, did you know that there's ROS packages for OP2 now?

If you are interested, you can try it by following the manual.

Hi,


Did you connect monitor when booting OP2?

If possible, please take a video and share it with us.

Also, how did you find out that the system crash?

Hi Will Son


Sorry for reply late !!

I think I need to correct the problem.

The system not crash, just demo cannot run, it's always show the Segmentation fault (core dumped) error, and Rx ON.

Need to reboot OP2 until Rx OFF.


Only have one photo, hope this can help you ~ thanks.

Hi,


Thank you for uploading the picture.

Our engineer mentioned that this seems like modified source code, and if you are getting Segmentation fault error, you'll need to debug the custom code.

If you want to restore the OP2 source code, please follow the procedure below.


1. Delete all files in the robotis folder

    $ rm - rf /robotis/*


2. Download the OP2 source code

    $ cd /robotis

    $ svn co https://svn.code.sf.net/p/darwinop/code/trunk/robotisop2 .


3. Build the source code and test the demo

    $ cd /robotis/Linux/project/demo

    $ make

    $ sudo ./demo


Please let us know if above method doesn't work for you.

In that case, I can think of an issue with the hardware.


Thank you.
