Can you flash 3.6 with 3.5 firmware?

I have 3.6 board can I flash it with 3.5 version firmware?
I want to use SPI option on the AS5048, it appears that SPI is only supported by TobinHall’s branch ( And, that branch only goes up to 3.5.

I think boards 3.5 and 3.6 are fw compatible. If it concerns you can’t you recompile with CONFIG_BOARD_VERSION=v3.6-24V in tup.config?
EDIT: sorry for the bad answer. of course you can’t recompile without upstream changes

Yes you can, I’ve done it before, but why would you?


You can try my RazorsEdge branch, which includes Tobin’s branch… but no guarantees that it will work (please tell me if it does or does not, we’re still trying to debug that one)

I will give it a try.
Thank you!

Thank you for pointing me in right direction. I was able to complete setup. However when I change state to AXIS_STATE_CLOSED_LOOP_CONTROL, I am not able to move motor using controller.move_incremental or any other command. There are no errors registered at all. Yet, motor does not move.
