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: GitHub - Optiboot/optiboot: Small and Fast Bootloader for Arduino and other Atmel AVR chips

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.
Thanks

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