I thought you didn't want a bootloader? You need to upload the .hex file.

Please do not cross-post. This wastes time and resources as people attempt to answer your question on multiple threads.

Sorry I thought my last post stalled a little.

My code seems to only work if it is uploaded onto optiboot. Not directly. What should the fuses be for an ATMega2560V running at 8Mhz on 3.3V?

Nick Gammon

I suggest you look here:

The BOOTRST fuse is the one that controls where programs start executing (bootloader or address 0).

I am unsure of the current settings used and the ones that I would need. I am very new to this so any help would be appreciated. Thanks

I have a sketch here:

That uploads from one Arduino to another without using the bootloader. It sets the fuse appropriately. You need an SD card (and board) however.
