We study the possibility of cogenesis of baryon and dark matter (DM) from theout-of-equilibrium CP violating decay of right handed neutrino (RHN) that aredominantly of non-thermal origin. While the RHN and its heavier partners cantake part in light neutrino mass generation via Type-I seesaw mechanism, thedecay of RHN into dark and visible sectors can create respective asymmetriessimultaneously. The non-thermal sources of RHN considered are {\bf (a)}on-shell decay of inflaton, and {\bf (b)} evaporation of ultralight primordialblack holes (PBH). After setting up the complete set of Boltzmann equations inboth these scenarios, we constrain the resulting parameter space of theparticle physics setup, along with inflaton and PBH sectors from therequirement of generating correct (asymmetric) DM abundance and baryonasymmetry, while being in agreement with other relevant cosmological bounds.Scenario {\bf (a)} links the common origin of DM and baryon asymmetry topost-inflationary reheating via RHNs produced in inflaton decay, whereas inscenario {\bf (b)} we find enhancement of baryon and DM abundance, compared tothe purely thermal scenarios, in presence of PBH with appropriate mass andinitial fraction. Although the minimal setup itself is very predictive withobservational consequences, details of the UV completion of the dark sector canoffer several complementary probes.
