Counting Points on Dwork Hypersurfaces and $p$-adic Gamma Function

We express the number of points on the Dwork hypersurface $$X_λ^d: x_1^d+x_2^d+\cdots +x_d^d=dλx_1x_2\cdots x_d$$ over a finite field of order $q \not \equiv 1 \pmod{d}$ in terms of McCarthy's $p$-adic hypergeometric function for any odd prime $d$.
