Arduino DUE, Marlin 1.1.9: fatal error: avr/io.h: No such file or directory Aloha :-) For some days I try to load Marlin 1.1.9 (2.0.0) as firmware on my Arduino DUE with RADDS. The following error message I get through the Arduino IDE: In file included from sketch\HAL.h:33:0, from sketch\MarlinConfig.h:39, from sketch\G26_Mesh_Validation_Tool.cpp:27: sketch\fastio.h:34:20: fatal error: avr/io.h: No such file or directory #include <avr/io.h> ^ compilation terminated. exit status 1 Fehler beim Kompilieren für das Board Arduino Due (Programming Port). I have already tried the folder "avr/" including the "io.h" in different directories to copy. But no matter what I do, each time the same error message appears. In the version 1.0.0 (which I use for years and which also works well) is "avr/io.h" does not exist. So I have no problems there. Does any of you have a solution?

Ok, I have it!
You have to create a folder 'avr' in '.../sketchbook/libraries' and copy the file 'io.h' into it.
Then it works.
