Is there a description of how to use onboard canbus?

[altraWeb]

There are two canbus ports on this board but i can't find any howto's / Description to use that for example with an EBB SB2209.

Thanks for any help

you need to flash the board with Katapult and set it in usb to can bridge mode.
you can follow instructions here: https://github.com/Esoterical/voron_canbus/tree/0bbde71d092cf38e8d3855190a9cf860a7f238ab

I flashed catapult per the katapult instructions. I can't get the board out of DFU mode. The DFU mode LED is on, but when I check dfu-utils -l there aren't any controllers in DFU. Only other thing I can do is double-click the reboot button and go into catapult flash mode. Hard reboot or anything doesn't fix the issue.

The documentation for this board is awful. I've had to get general information from other user guides to try to piece together information. For a "Premium" board, this is really sub-par documentation.

Hi!
So... I'm having a good learning curve regarding "Kraken and the CAN", until now I wasn't able to make it work but I think I got the direction right this time ( maybe not haha ), the main thing is that I wanted to use the Rpi UART mode comms with the CANBUS function and for what I can see or for what I cannot see it's that it's a little more complicated than I would like...

Getting back to the problem, I think I had the same problem as you, although I don't know if it is the same problem, the partial solution ( since it is not what will make the CAN BUS work ) is that you have to rewrite the default firmware to the mainboard (available in this repository ). Despite the fact that the DFU_Mode LED is stuck in the ON state I could put the board on DFU Mode as usual ( hold Boot + Reset), after I followed the instructions from this repository and used the command: sudo dfu-util -d ,0483:df11 -R -a 0 -s 0x8000000:leave -D ./Kraken_H723_bootloader.bin the board came back to life :-). Now I will try to make everything the right way ( or at least try ), for the moment I will use the Rpi USB to communicate with the KRAKEN using the last one as a CAN bridge, by far the best tutorial I saw about is the ESOTERICAL GUIDE mentioned above.

I hope everything went well with your board, I'm writing all of this since it could help someone like me.
PS: If someone knows how to make the KRAKEN use UART to talk to the Rpi and at the same time work as a CAN bridge please let me know 😃.
