So I am not sure what I am doing wrong here. I have a bootloaded my 328p with the 8mhz bootloader, I have set the fuse settings to an internal oscillator, brownout detection is off, but yet when I fire up my little blink program it runs at 5V and not at 3.3V. We have a variable voltage supply and we turned it down slowly to see where it powers down, the atmega seems to die at 3.45V.
Steps I am following: 1. Insert atemega328p into Arduino UNO 2. attach AVR pocket programmer 6 pin connector to the ICSP header on the UNO 3 Select board in Arduino environment(ATmega328 on a breadboard (8 MHz internal clock)) 4 Burn bootloader 5. Remove from UNO 6. place in bread board, attach LED to CORRECT pin 7. attach power and ground @ 3.3V from arduino UNO 8. Feel sad at my failure as nothing happens 9. hook up 5V from UNO 10. Feel a mixture of confusion and frustration as every 5V blink mocks me.

I have tried several times through out various projects that I have done to figure out this internal oscillator thing. any ideas?
