Firmware .bin VS .hex

[Satchmo]

Basic Information:

Printer Model: Ender3
MCU / Printerboard: creality 1.1.5
Host / SBC CB1+PI4B
klippy.log X

Hi all! I would like install klipper but when I create the firmware with the menu config and the make command I obtain a .hex
The 1.1.5 card use .bin file, I found many info specialy around a boot loader but I don’t know how to use this infos.

For exemple:
Note, a number of Melzi boards are shipped with a bootloader that
requires the following command to flash the board:
avrdude -p atmega1284p -c arduino -b 57600 -P /dev/ttyUSB0 -U out/klipper.elf.hex
For v1.1.5 silent boards, the following command is used:
avrdude -p atmega1284p -c arduino -P /dev/ttyUSB0 -b 115200 -U flash:w:out/klipper.elf.hex
If the above command does not work and “make flash” does not work
then one may need to flash a bootloader to the board - see the
Klipper docs/Bootloaders.md file for more information.

Or this

So I think I need help, Thanks!

I found.
The link takes you to the right moment in the video:

How to flash a Bootloader and Firmware onto an 8bit Creality Mainboard (or any other AVR board)

Just it is described in the documentation:

Yep thanks but I’m French and on internet many things is in english.
If you’re not really familiar with the raspberry environment (CB1 bigtreetech for this case), it’s hard to find your way around.
