Hi Dave, I figured out the problem. As I mentioned in my original post, I had to use a precompiled i2c-Bootloader because I got a message that the bootloader was too new. I went back to my original buildroot directory and grabbed the i2c-io.hex and i2c-Boot-m128-16MHz.hex from there. I installed those and everything works great. Thanks for the help, -Russell On Mon, Aug 30, 2010 at 1:50 PM, Dave Hylands <dhy...@gm...> wrote: > Hi Russ, > > On Sat, Aug 28, 2010 at 5:42 AM, Russ Morin <rus...@gm...> wrote: > > Hi Dave, > > > > Yes, I did program the fuses using pgm-fuses-bootloader.
