CAN connection not working. #17

Open Engineer997 opened 1 year ago

Engineer997 commented 1 year ago

I am running Raspberry Pi OS Debian Bullseye, Klipper, KlipperScreen, Mainsail, and Moonraker.

The CAN bus does not connect to my Octopus or Hermit Crab Can edition. This is not an issue when using a Raspberry Pi 4 B and a CAN Hat with the same Config files. I have CANH/CANL connected to the USB D+/- connections from the USB-C port on the Raspberry Pad 5 with the dip switch for CAN on the on position and the switch for the CAN connection in the correct position as per the manual.

User manual for raspberry pad 5 needs a revision to include an additional step for setting up the CAN bus after the current last step “ MCP2515 is operating，correct return should be as following： [ 8.680446] CAN device driver interface [ 8.697558] mcp251x spi0.0 can0: MCP2515 successfully initialized. [ 9.482332] IPv6: ADDRCONF(NETDEV_CHANGE): can0: l"

the section that needs to be added is as follows: Input sudo nano /etc/network/interfaces.d/can0 command to create a new file named can0, and write the following content auto can0 iface can0 can static bitrate 250000 up ifconfig $IFACE txqueuelen 1024
