  We consider a block $B$ of a finite group with defect group $D \cong
(C_{2^m})^n$ and inertial quotient $\mathbb{E}$ containing a Singer cycle (an
element of order $2^n-1$). This implies $\mathbb{E} = E \rtimes F$, where $E
\cong C_{2^n-1}$, $F \leq C_n$, and $E$ acts transitively on the elements in
$D$ of order $2$, and freely on $D \backslash \{1\}$. We classify the basic
Morita equivalence classes of $B$ over a complete discrete valuation ring
$\mathcal{O}$: when $m=1$, $B$ is basic Morita equivalent to the principal
block of one of $SL_2(2^n) \rtimes F$, $D \rtimes \mathbb{E}$, or $J_1$ (where
$J_1$ occurs only when $n=3$). When $m>1$, $B$ is basic Morita equivalent to $D
\rtimes \mathbb{E}$.
