looks like it actually solved my issue, thank you !

Please post the results of M122 and M98 P"config.g" please.
Does the firmware version between the two duets match?

You can change the device node, which determine the CS pin. The extra trfrdy pin is configurable.

But it's not adviced to share the spi bus, probably better off using the second spi bus on the pi.

In any case see /opt/dsf/conf/config.json or something similar

Found it :
i used the Pn parameter to redirect it to USB (P1), from there i just have to read the TTY output on the raspberry and do whatever i want with it

Thank you for your answers,
Hopefully the full can support will come in the future, in the meantime i will try to find a way around (by adding a node on the can bus that will do the translation for instance)
