Updating Klipper Firmware on a Fly-Super8 in USB to CAN Bridge mode

How to update the klipper firmware running on a Fly-Super8 in USB to CAN Bridge mode

Edit me

Configuring and installing Klipper for USB to CAN bridge mode

Warning: Super 8 Version 1.0 does not support USB to CAN bridge mode.

Tip: To read more about the KCONFIG_CONFIG option, see here

Note: If you are planning to use CANBoot bootloader with Klipper in USB to CAN bridge mode you will want to configure CanBoot in USB mode

Compile Klipper firmware for usbtocan for USB to CAN Bridge Mode

Note: Repeat these steps if a klipper update requires flashing new firmware to the MCU.

ssh into your klipper host console
cd to the klipper directory
```
cd klipper
```

Run make clean

make clean KCONFIG_CONFIG=config.super8

Important: If when running the above command you get this output

Using default symbol values (no 'config.super8')

Configuration saved to 'config.super8'

Then you need to set all the correct settings when running make menuconfig below.

Open menuconfig

make menuconfig KCONFIG_CONFIG=config.super8

Check to make sure the following settings are set
- Enable extra low-level configuration options : Checked
- Micro-controller Architecture : STMicroelectronics STM32
- Processor model: STM32F407
- Bootloader offset: 32 KiB bootloader
- Clock Reference: 8 MHz crystal
- Communication interface - USB to CAN bus bridge (USB on PA11/PA12)
- CAN bus interface - CAN bus (on PB8/PB9)
- CanBus Speed: 500000
  
  Klipper Menu Config USB to CAN
Quit (and save if changes were made) the configuration
Run Make to compile the firmware

make KCONFIG_CONFIG=config.super8 -j4

Updating Klipper USB to CAN Bridge mode firmware with Katapult over USB

Look in your printer.cfg file and make note of the serial ID for your board.

Run the make flash command to flash the firmware

make KCONFIG_CONFIG=config.super8 flash FLASH_DEVICE= {Your serial ID here }

Example

make KCONFIG_CONFIG=config.super8 flash  FLASH_DEVICE=/dev/serial/by-id/usb-Klipper_stm32f407xb_170038000650314D35323820-if00 

Your Fly-Super 8 should now have the Klipper firmware running on the board updated to the latest version.
