Atmega328p-mmh bootloaders required.

Hi guys,
Recently i purchased a new Atmega328p-mmh chip from Atmel,Some how i manage to solder it on PCB properly, attached SMD crystal and other components onto it,But i required bootloaders to flash init first to make it alive, I searched on the internet for the files, But all in vain (As per my searching techniques),It would be glad if somebody provided me those files.
Thank you very much :slight_smile:

The bootloader files used on the Arduino boards are located inside the Arduino IDE install folder at, for example the bootloader used on the Uno: hardware/arduino/avr/bootloaders/optiboot/optiboot_atmega328.hex

If you want to use the latest version of Optiboot the bootloader files and source are available here:

Thank you vey much for the reply sir, Is that HEX file supports all Atmega 328 series MCUs.? Like Atmega 328p ,Atmega 328p-AU, Atmega 328p-mmh likewise.

Yes. The bootloader will be the same for all of the different packages.
