I am going present new developments on the Cosmic-Ray driven, galactic dynamo, modeled by means of direct, resistive CR-MHD simulations, performed with ZEUS and PIERNIK codes. The dynamo action, leading to the amplification of large-scale galactic magnetic fields on galactic rotation timescales, appears as a result of galactic differential rotation, buoyancy of the cosmic ray component
and resistive dissipation of small-scale turbulent magnetic fields. The new results include demonstration of the global-galactic dynamo action driven by Cosmic Rays supplied in supernova remnants. An essential outcome of the new series of global galactic dynamo models is the equipartition of the gas turbulent energy with magnetic field energy and cosmic ray energy, in saturated states of the dynamo on large galactic scales.
