I have a rpi 2 with a Gertduino board, been having quit a time get this running.
1: Installed Friends of the unicorn instruction and could not get the Gertduino to program.
2: After many installs I used to avrdude 5.10-4 for the Gertboard and managed
to upload my sketch with no RC-1 error.
3: Found out that I have to remove the reset on the Gertduino to see my sketch run.
4: After reading the post here on disabling the device tree it all seems to work fine.
My knowledge is limitted but growing but the way it is right now i can not access the
Atmega 48 and disabling the device tree seems to be a short term fix. Is there another
way to do a better installation and could I adding a line in the config.txt and enable the
device tree ?
