Isn't there any original Atmel Bootloader (i.e. over UART) for all the Megas around?
There are a lot of self programmed bootloader codes, but I don't want to deal with this issue too much and I want to trust the code !
Some uP's like the AT89C51RD2 has a downloadable bootloader from Atmels HP, and is programmed via the ready to go FLIP Software - that's it !
Why should I invest so much time in making or editing code just for programming the flash ?
I need some "ready-to-go" bootloader solution for programming an ATMega 2560 over the USART, no debugging, no problems !
