\frametitle{UBI Volumes}
\begin{itemize}
\item something like a partition in common systems
\item but more flexible
\item ubi exchanges eraseblocks between volumes (for bad block handling,
wear-leveling)
\item non-linear mapping of physical eraseblocks (peb) to logical eraseblocks
(leb)
\item e.g. a volume out of 3 blocks could use peb 813, 28, 1017
\end{itemize}
\end{frame}

\begin{frame}
\frametitle{Volume type}
\begin{itemize}
\item static
\begin{itemize}
\item used for a single binary
\item no filesystem
\item easy readable e.g. by a bootloader
\end{itemize}
\pause
\item dynamic
\begin{itemize}
\item used for filesystems
\end{itemize}
\end{itemize}
