Hermit Crab CAN issues

[Himmywashere]

Hello,

I'm currently working on setting up the Hermit Crab Can Edition with a BTT Octopus v1.1 and Raspberry PI 3B+. I have completed the wiring and have started to try to configure Klipper. I currently have Mainsail installed and it is recognizing my octopus board.

I am trying to get my raspberry pi to recognize the CAN-HotMode board. I have followed the steps on the github and have flashed the new firmware to the board. When I get to the step of running dmesg | grep -i '\(can\|spi\)', I am not getting the expected output. I am only getting:

[   97.663614] can: controller area network core
[   97.674453] can: raw protocol

It is not showing MCP2515 successfully initialized. Additionally, when I run "~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0" it is showing "no such device".

I am at a loss and have tried flashing klipper firmware to the CAN-Hotmode board twice now, once with windows and again with the raspberry pi. Any help would be greatly appreciated.

Hi,

The two firmware supports different interfaces. It needs to be connected to the CAN interface of the octopus motherboard.
