Hello all,
under eclipse, I tried to burn a simple bootloader on my arduino Mega2560, one led on pin 38 blink 3 times and jumps to 0.
I set the fuses like this : low FF, high D8, ext FF, lockBit 0F
Burn is OK, result led on pin 38 blinks, but all the time.
Then I burned a simple code who just blink a led on pin 39. No fuse written.
I expected that the led on port 38 flashes 3 times, it jumps to 0 and the led on pin 39 flashes...
It's not the case, only the led on pin 39 flashes, like if there was no bootloader.
What is wrong, do you have ideas?
Thank you
