Is anyone using the optiboot bootloader on arduinos running at 8 MHz? I'm myself trying to make it work on a custom board (3.3V, 8MHz) without success. For the standard bootloader, I usually take the one built for the "atmega328_pro8" platform , just changing LFUSE to 0xE2 (internal 8MHC RC oscillator) and it works great. However, doing the same for optiboot does not work. I get no pin flashing, just a quick blink on the RX/TX LED's. I'd even say that the uC is not being reseted but I'm not sure.
Thanks guys for your feedback.
