The WRS is now shipped with a SCB v3.4 with the following main changes:\footnote{The WRS v3.4 is still shipped with minibackplane v3.3}
\begin{itemize}
\item New dataflash \texttt{AT45DB641E} to replace the obsolete \texttt{AT45DB641E}.
\item New configuration of the PLL: \texttt{CLK1} can be 10MHz.
\item\texttt{CLK2} output from FPGA and latched by PLL to improve clock stability.
\item PPS input has a configurable 50$\Omega$ configuration.
\item Correct reset signal for \texttt{CDCM61002}.
\end{itemize}

\subsection{Release v4.1}
\begin{frame}{\insertsubsectionhead}
To support the new SCB v3.4 we have created the new release v4.1. It now supports:
\begin{itemize}
\item Detection of new dataflash \texttt{AT45DB641E} in kernel \& barebox.
\item Setup of the new PLL configuration:\\\emph{The CLKx outputs are currently desactivated, but we expect to release soon a v4.2 with this modification.}
\item{New hwinfo saved in Dataflash partition by manufacturer:}
\begin{itemize}
\item MAC address of all the ports.
\item SCB: version, serial number, FPGA type, batch.
\item Manufacturer, etc...
\end{itemize}
\end{itemize}

\subsection{Updating with correct HW info}
\begin{frame}{\insertsubsectionhead}
\begin{alertblock}{Important}
Since SCB v3.4, hwinfo is saved by manufacturer.
If you want to upgrade from v3.3 to the new v4.1 firmware we suggest you to first update the correct hwinfo.

Seven Solutions provides a tarball with the correct hwinfo for all v3.3 switches that you can download from:
