    Raspberry pi 2 and gertduino


      I have a gertduino wich works fine on my Raspberry Pi B+. Than i did buy a Raspberry Pi 2. My Gertduino don't work on the RPi 2. I checked everything and Even installed a new version of Raspbian on my RPi B+ and installed the gertduino software again on both the RPi 2 and RPi B+. I am sure both sytems have the same software now and the same settings.

      I can program the gertduino on the RPi B+ but NOT on the RPi 2. I use the same avrdude from gordon on both RPi's. but ./avrsetup doesn't work on my RPi 2. I don't know what to do, please help me.

          Try the following because this may be software related...


          sudo apt-get update
          sudo apt-get install python-dev
          sudo apt-get install python-rpi.gpio

            GertDuino is this where you got the software from?

              Well, I've also a Gertduino with RPi 2.  Working well after struggling for a few days.  What I discovered, the GPIO behavior in Raspbian had been changed.  The reset pin for Gertduino (GPIO 8 on RPi) is now in default Input mode, so the level sensed by the Gertduino will be LOW (reset active, not running).  With the script reset_off in the Gertduino manual, the reset pin will revert back to Input mode after the last statement (echo 8 > /sys/class/gpio/unexport).  So, the Gertduino uC will not run.  I solution is to run the reset_off script manually, and leave the last statement.  I've no problem to program the uCs on Gertduino, either by avrdude from Gordon or by using Arduino IDE (with patching).


              My 2 cents.
