both are wrong
the whole snippet that assigns these two globals needs to go.

the logic used to be that you could do a boardname override, which would lock system parameters in place
and stop the learning logic
(say, if provided by a manufacturer)

with the boardname stuff gone, those parameters shouldn't be set like this
