The Klipper firmware does not need to be upgraded often on the Octopus Pro MCU and LDO Nitehawk-36 toolboard. The only time it was upgraded was when there were deprecation warnings since Klipper is kept up to date.
Here are some notes on upgrading the firmware since I did not use the correct settings when building and flashing the firmware which meant I had to perform additional lower level loading of the correct firmware.
Octopus Pro settings
Start Klipper firmware configuration:
cd ~/klipper
make clean
make menuconfig
Select:
- Select
Enable extra low-level configuration options - Set the micro-controller architecture to
STMicroelectronics STM32 - Set the Processor model to
STM32F446 - Set the Bootloader offset to
32KiB bootloader - Set the Clock Reference to
12 MHz crystal - Set the Communication interface to
USB (on PA11/PA12)
Build and flash the firmware:
make
sudo service klipper stop
make flash FLASH_DEVICE=/dev/serial/by-id/usb-Klipper_stm32f446xx_19003A000951313133353932-if00
sudo service klipper start

Nitehawk36 settings
Start Klipper firmware configuration:
cd ~/klipper
make clean
make menuconfig
Select:
- Select
Enable extra low-level configuration options - Set the micro-controller architecture to
Raspberry Pi RP2040/RP235x - Set the Processor model to
rp3040 - Set the Bootloader offset to
16KiB bootloader. Not setting this will erase the Katapult bootloader! - Set the Communication interface to
USBSERIAL
Build and flash the firmware:
make
sudo service klipper stop
make flash FLASH_DEVICE=/dev/serial/by-id/usb-Klipper_rp2040_313631313202C86C-if00
sudo service klipper start
