I have been using arduino since several years now. Yesterday I got a prompt telling new version is available! Newer is better (I thought), so uninstalled the old one (I don’t know the version it was), and installed the new 1.6.8.
Nowdays I play with a 3D printer, what has a Melzi main board with an ATMEGA 1284p chip on it, so I downloaded the shanguino bootloader from here (as I did before), and copied the sanguino folder into c:\Program Files (x86)\Arduino\hardware\ folder, as before. When I started the Arduino ide, the new board didn’t show up in Tools/Board menu. After some research, I found the info about to put these modules in two folder deep: First is the vendor, the second is the architecture. So I moved the contents of the sanguino folder into an atmega subdirectory, see in attachment. Now the Melzi 1284p 16 mhz has appeared in Boards menu, but when I try to compile some code, I get the following error message:
Board sanguino:atmega:atmega1284 doesn’t define a ‘build.board’ preference. Auto-set to: ATMEGA_ATMEGA1284
exec: “-w”: executable file not found in %PATH%
Error compiling for board Melzi 1284p 16mhz.
Please help me to solve this problem. Google can’t help me.
