Hi,
as I explained in the original commit message, CAN is definitely there
and is working perfectly at least on A40i.
I know it was removed from the user manual, but I personally verified
that it is working.
Maybe you can tell why CAN should be removed besides not being described
in the manual? Are there some hardware or maybe license issues?
Thanks!
