No connection to the arm at all

[FineApple-de]

After a few days of fail and error to connect the arm with my desktop, I hope you can help.

I used the arm before and everything works out fine, he did what he should do but now, I don´t even get a connection to the arm.
Maybe I should mention, that I don´t really have a plan of programming, I know some basics and how to use and interact with software.

Following a list of what i´ve done and which response I get from the software.
1.

• a. Connecting the USB to the desktop

• b. Starting the software

• c. “refresh the USB port” and trying to connect

• d. Response from the software:

That´s it. I don´t know if the lines help, but maybe they´ll do.

All the best and thanks for helping me.

I also have major issues with connecting over USB. Some days I can connect quickly, other days I don't get a connection all day. I've tried different computers, python command line, python program, included GUI. They all have this issue. Could this be an issue with the g2core firmware?

[virtualmagician]

same issue for me.
connection to arm worked only once in 100+ connection attempts.

[FullMetalRico]

So, is there any solution to this ? I am facing the exact same problem and i would like to flash a fresh g2core but as far as i understand the arm will not work then because of the different pinout. Is is possible to get the original .bin or the pinout?

[mechaphone]

I had the same issue for a long time and found the solution that seems to work.
Apperantly you have to reset the Arduino Due. The problem is that it is hidden on the floor of the controller box.
If you drill a small hole you can dip the reset button wit a wooden(!!!) stick. After you reset the Arduino Due the software will connect and you are good to go!

The opening needs to be right here and the sick goes about 2 to 3 cm in. Then just tilt it and you'll hear the click.
Watch the terminal and see the magic happen ;)
