Issue with Serial Port and Arduino IDE on UDOO x86

Hello,

I'm having a problem selecting the serial port to upload a ketch to the internal Arduino.
When I try to select Tools->Port, the voice is greyed out and I can't select anything.

I've found a post with the same issue here (https://www.udoo.org/forum/threads/solved-uploading-a-sketch-serial-port-issue.99/).
I've tried to solve it with the advice reported there, creating a symbolic link to the internal serial port (/dev/ttymxc3) with a command line in the terminal, but nothing.

I'm running the last release of Ubuntu Studio.
I'm loosing for sure something obvious...
Can you help me please?

 

That topic is for a Udoo dual/quad and solution will not work. It looks like your installation of Arduino IDE including Arduino 101 board manager failed.

Please deinstall the Arduino IDE completely including everything from Arduino in your home/.arduino15 folder.

Then install it again according the instructions from here https://www.udoo.org/docs-x86/Arduino_101_(Intel_Curie)/Getting_Started_with_Arduino_101.html

 

Ok, thank you!

Now I see the serial port from the IDE, but it seems to have another problem.
When I try to upload a sketch on the board, it give me this errors:

Code:

I'm using the 1.8.5 of the IDE, selected Arduino/Genuino 101 as board.

 

Did you remove the symbolic link you created to the serial port?

 

I'm not sure what are you talking about, but I've also tried with this option .

 

I've downloaded the Genuino 101 Library, tried to follow the guide here, but the scripts didn't find the directories.
Maybe that is the problem?

 

Sorry, I've missed the link: https://www.udoo.org/docs-x86/Arduino_101_(Intel_Curie)/Getting_Started_with_Arduino_101.html

 

From your first post:

If that symbolic link is still there and pointing to the wrong serial port (/dev/ttymxc3) then you also have the kind of issues you are reporting now. So you have to remove it.

 

Yes, but I have rebooted. I haven't modified the rc.local, so the link shoud not be there anymore, right?

 

Yes it should not be present. You could try the following (used to be a fix for older Arduino IDE and location of the rule scripts could be different):
chmod +x ~/.arduino15/packages/Intel/hardware/arc32/2.0.2/scripts/create_dfu_udev_rule sudo ~/.arduino15/packages/Intel/hardware/arc32/2.0.2/scripts/create_dfu_udev_rule

 

Thank you!
It wasn't working also with those lines of codes. Tried to reinstall all the things (IDE and Curie libraries), used again the commands and now it seems to work fine.

I've tried also on Win 10 for curiosity. Initially the serial port was accessible but the sketches didn't upload at all. I've uninstall the curie 2.0.2 library and tried with a previous versione, the 1.0.6 and now it's uploading every sketch like a charm.
I've rebooted after every change (install and uninstall)

Thank you for your help, it has been crucial.
