ATmega Hex Uploader

Hi,

I made a new setup not so sketchy... and this time seems that the sketch is working.

I´am able to write and verify the code.

One thing that i noticed is that when i wirte a sketch to the Mega2560, if i trie to reprogram the board via IDE i´m not able.
You are erasing the flash and with the bootloader, is that correct?

When the MCU starts the program, it starts directly from the start of the code without any bootloader?

Can you clarify this to me?

Regards
