Since documentation has been somewhat lacking... here is a quick write-up to get started!

NOTE Do not forget the 120R jumper just above the canbus connector!
As julianschweizer pointed out, the CanBoot project has been renamed Katapult
First, ssh into your system and from the home directory pull the latest version of katapult
git clone https://github.com/Arksine/katapult.git
Enter directory and compile Katapult
cd ~/katapult
make menuconfig
Use the following config
Micro-controller Architecture (STMicroelectronics STM32) --->
Processor model (STM32G0B1) --->
Build CanBoot deployment application (Do not build) --->
Clock Reference (8 MHz crystal) --->
Communication interface (CAN bus (on PD12/PD13)) --->
Application start offset (8KiB offset) --->
(250000) CAN bus speed
() GPIO pins to set on bootloader entry
[*] Support bootloader entry on rapid double click of reset button
[ ] Enable bootloader entry on button (or gpio) state
[ ] Enable Status LED
Now build Katapult
make clean
make
Enter klipper directory and compile klipper
cd ~/klipper
make menuconfig
Use the following configuration
[*] Enable extra low-level configuration options
Micro-controller Architecture (STMicroelectronics STM32) --->
Processor model (STM32G0B1) --->
Bootloader offset (8KiB bootloader) --->
Clock Reference (8 MHz crystal) --->
Communication interface (USB to CAN bus bridge (USB on PA11/PA12)) --->
CAN bus interface (CAN bus (on PD12/PD13)) --->
USB ids --->
(250000) CAN bus speed
() GPIO pins to set at micro-controller startup
Now build klipper
make clean
make
First flash your Manta M8P by entering DFU mode
- Hold down
Boot0ANDReset - Release Reset and then
Boot0
Make sure that your board is in DFU mode by running
lsusb
This should show you the Manta M8P as Bus 001 Device 008: ID 0483:df11 STMicroelectronics STM Device in DFU Mode.
When you have validated that the Manta M8P is ready, flash Katapult.
sudo dfu-util -a 0 -D ~/katapult/out/katapult.bin --dfuse-address 0x08000000:force:leave -d 0483:df11
Then reset the board by pressing Reset and then put the board in DFU mode once again to flash Klipper.
sudo dfu-util -a 0 -d 0483:df11 --dfuse-address 0x08002000 -D ~/klipper/out/klipper.bin
Now the board should be running Katapult with Klipper. Verify by pressing Reset once again and then run lsusb.
The board should be identified by Bus 001 Device 011: ID 1d50:606f OpenMoko, Inc. Geschwister Schneider CAN adapter.
To enable the canbus on the raspberry pi you need to create the interface file
sudo nano /etc/network/interfaces.d/can0
Paste the following content
allow-hotplug can0
iface can0 can static
bitrate 250000
up ifconfig $IFACE txqueuelen 1024
To bring the canbus interface can0 up simply run sudo ifup can0. If everything worked you should now be able to query your Manta board using python3 ~/katapult/scripts/flash_can.py -q.
This command will present you with the UUID of the Manta board which you need to reference in your printer.cfg.
[mcu]
canbus_uuid: <your uuid goes here>
canbus_interface: can0
The procedure is more or less the same for the EBB2209 board.
NOTE I don't know with 100% certainty that the heater won't turn on when the board is in DFU mode so keep the heater cartridge disconnected just to be safe!
NOTE Do not forget the 120R jumper on the bottom of the board (beside BL-Touch connector)!
Just enter the katapult folder from the last step and re-run menuconfig.
cd ~/katapult
make menuconfig
Use the followin config
[*] Enable extra low-level configuration options
Micro-controller Architecture (STMicroelectronics STM32) --->
Processor model (STM32G0B1) --->
Bootloader offset (8KiB bootloader) --->
Clock Reference (8 MHz crystal) --->
Communication interface (CAN bus (on PB0/PB1)) --->
(250000) CAN bus speed
Now compile Katapult
make clean
make
Enter klipper directory and compile klipper
cd ~/klipper
make menuconfig
Use the following config
[*] Enable extra low-level configuration options
Micro-controller Architecture (STMicroelectronics STM32) --->
Processor model (STM32G0B1) --->
Bootloader offset (8KiB bootloader) --->
Clock Reference (8 MHz crystal) --->
Communication interface (CAN bus (on PB0/PB1)) --->
(250000) CAN bus speed
First flash your EBB2209 by entering DFU mode
- Hold down
BootANDRst - Release Reset and then
Boot
Make sure that your board is in DFU mode by running
lsusb
This should show you the EBB22009 as Bus 001 Device 008: ID 0483:df11 STMicroelectronics STM Device in DFU Mode.
When you have validated that the board is ready, flash Katapult.
sudo dfu-util -a 0 -D ~/katapult/out/katapult.bin --dfuse-address 0x08000000:force:leave -d 0483:df11
Then reset the board by pressing Rst and then put the board in DFU mode once again to flash Klipper.
sudo dfu-util -a 0 -d 0483:df11 --dfuse-address 0x08002000 -D ~/klipper/out/klipper.bin
Now the board should be running Katapult with Klipper. Verify by pressing Reset once again and then run lsusb.
The board should be identified by Bus 001 Device 011: ID 1d50:606f OpenMoko, Inc. Geschwister Schneider CAN adapter.
Since you already have a canbus network up and running, simply run python3 ~/katapult/scripts/flash_can.py -q to get the UUID for the EBB2209 board.
Using the UUID from that command you should reference the board the same way you did your Manta board but this time with a identifier.
[mcu EBBCan]
canbus_uuid: <your uuid goes here>
canbus_interface: can0
Now you need to update your printer configuration to use the appropriate pins and if you named your mcu EBBCan you can more or less copy the example configuration!
Happy printing!
I figured it out and after I did the enable on Raspberry pi section inbetween the Manta and EBB in this guide, Yes i realize I use a CB1,and maybe you do to, but after I did those steps I was able to look up the UUID
