Me and my colleague just discovered that when he compiled our project, some features no longer worked on the target.
We nailed it down to avr-gcc.exe, which were different versions. Mine had date 2007-12-21 and size 215040 bytes and works fine.
His version was downloaded last week.
They create different sized code and as mentioned, the later one is not working.
I don't really know what to do here. I'd really like to use the latest versions of everything, but it's scary that the compiled code is no longer working.
