I am having trouble compiling the latest LUFA (110528)for bootloader and USB-serial for my Uno (Atmega8U2).
I have followed the instructions in http://arduino.cc/forum/index.php/topic,111.0.html but this is for an earlier version of LUFA and the same method does not work with the new one.
The standard makefile in the LUFA downloads has MCU = at90usb1287. Just changing this to Atmega8U2 doesn't work.
Has anyone compiled the latest LUFA and if so, what variables did you change in the makefile?
