### Description

We determine the masses and the pseudo-scalar decay constants of charmed mesons using non-perturbatively O($a$) improved Wilson quarks. Our analysis is based on the $N_{\rm f}=2+1$ ensembles using open boundary conditions, generated within the CLS effort. The status of results for 2 lattice spacings, $a\approx 0.086$ fm and $a\approx 0.064$ fm, will be presented. The pion mass is varied from 420 to 220 MeV. This is part of a continuing analysis by the RQCD and ALPHA Collaborations, aiming at a stable continuum extrapolation using several lattice spacings. To extrapolate to the physical masses, we follow both, the $(2m_l+m_s)=\mathrm{const.}$ and $m_s=\mathrm{const.}$ line.
