I have a Gertduino board, a Raspberry Pi B+ an a Raspberry Pi 2.
On the Raspberry Pi B+ i can do everything with the Gertduino, programming, setup and erase.
On the Raspberry Pi 2 i can do nothing With the Gertduino, not programming, not setup and not erase.
On both Raspberry's i installed the latest noobs software, rasbian.
I installed on both Raspberry's Arduino and the same software from Gordon Henderson.
I don't understand what is going wrong, please help me
