Katapult Configuration for the Fly-Super8Pro H723 on CAN

How to Configure Katapult for CAN bus Operation on the Fly-Super8Pro H723

Edit me

Configuring and installing Katapult bootloader for CAN bus

Overview

Katapult allows you to update your mainboard via CANbus, so no rebooting and rewiring is necessary. We recommend using Katapult for this additional convenience.

Install Katapult package

Note: The bootloader software formerly known as CANBoot has been renamed to Katapult

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

ssh into your klipper host console

Clone the Katapult firmware to your Klipper Host

cd ~/
git clone https://github.com/Arksine/katapult

From your Fluidd or Mainsail web UI Edit Moonraker.conf and add the following at the bottom to allow Moonraker to manage updates to Katapult.
```
[update_manager Katapult]
type: git_repo
path: ~/katapult
origin: https://github.com/Arksine/katapult.git
is_system_service: False
```

Compile Katapult firmware

cd to the Katapult directory
```
cd ~/katapult
```

Run make clean

make clean KCONFIG_CONFIG=config.super8proh723

Open menuconfig

make menuconfig KCONFIG_CONFIG=config.super8proh723

Important: As of FlyOS v3.1, the default CAN speed is 1000000. These instructions have been updated to reflect that speed as default.
Your host system may be set up for a different default CAN speed. Use nano /etc/network/interfaces.d/can0 to check the speed

Set the following settings
- Micro-controller Architecture (STMicroelectronics STM32)
- Processor model (STM32H723)
- Build Katapult deployment application (128KiB bootloader (SKR SE BX v2.0))
- Clock Reference (25 MHz crystal)
- Communication interface (CAN bus (on PB8/PB9))
- Application start offset (128KiB offset)
- (1000000) CAN bus speed
- () GPIO pins to set on bootloader entry
- [*] Support bootloader entry on rapid double clip of reset button
- [ ] Enable bootloader entry on button (or gpio) state
- [ ] Enable Status LED
  
  Katapult Menu Config CAN
Quit and save the configuration

Run the make command to compile the firmware

make KCONFIG_CONFIG=config.super8proh723 -j4

You should now have a deployer.bin file at ~/katapult/out/

USB Power Jumper

Add a jumper as shown below to ensure the board can be powered from USB power.

Flash Katapult to the Fly-Super8Pro MCU

ftp to your klipper host with an FTP client like FileZilla
- open the folder ‘~/katapult/out’
- download deployer.bin to your PC
place the MCU MicroSD card into a card reader and connect it to your PC.
ensure that the SD Card is formatted as Fat32. If in doubt use the SD Card Formatter.
Copy the deployer.bin file to the root of the SD card
rename deployer.bin to firmware.bin
Eject the SD card from the PC
Insert the SD card into the Fly-Super8Pro SD card Slot.

Fly-Super8Pro SD card
Press the Fly-Super8Pro reboot button

Fly-Super8Pro reset button
Wait a few minutes
Open a putty SSH session to the Fly-Super8Pro and log on
run lsusb to verify the MCU has been discovered as a USB device

Example lsusb Output
Continue to the Klipper for CAN bus configuration section
