Programming with Arduino from external Linux PC

Hello,

I try to program the arduino with the official, patched IDE from a second PC (Ubuntu 12.04, 64 bits).
I followed the instructions on:
http://www.udoo.org/ProjectsAndTutorial ... lioID=1394

Open questions:
1. shall I select Arduino Duo-> Programming port or Arduiono-> Duo native usb port?
2. whatever I select, programming fails with the message "No board found at the selected port..."

But I cannot even select a port, the menu entry Tools->Port is disabled.

If I plug in the usb cable to the board I can see the following entry if I do lsusb:
Bus 003 Device 008: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device

So I guess that the hardware connection is established.

Do I need a special driver?

Any hints welcome.

Hello,
I could solve this problem myself.

1. add yourself to the group dialout:
sudo adduser <USERNAME> dialout

2. log out and log in again (otherwise this change
does not became valid)

3. in the IDE, select Arduino Due, programming port

4. in tools->port select /dev/ttyUSB0

It would be nice if these hints could be added to the tutorial.

Best regards:

Uwe

 

Hi Uwe

Great that not only you solved your issue, but you reported back here with clear steps for others. Many thanks!

Good point on the documentation, hopefully the technical authors won't forget but we'll nudge them till they get it done.

 

But on a linux side, what does the 'dialout' command do? Does it give user more rights or priveleges?

 

pavelexpertov, what the "sudo adduser <USERNAME> dialout" command is doing is adding the user to the dialout group, which is the group required by a user to interact with serial devices (such as ttyUSB0)

 

Thanks for reply!!!!!!
