Definition of a map of (pre)spectra in HoTT

This is surely a typo. Pretty much everything about spectra takes place in the pointed category and every map in sight is pointed. I'm not familiar with this particular exposition in the context of HoTT, but I've never seen any similar definition in any other context that would use unpointed maps. (And if the $f$ maps were not pointed, it is not clear what $\Omega f_{n+1}$ would even mean in the specification of $p$.)
