+\section{Bootloader}
+For the first released hardware sample of moray ruby 2 for the WCA side the
+bootloader v1.0.0.0 has to be used. The release is available
+\href{http://dabsvn01.internal.novero.com/svn/0\_31X\_P0513\_moray\_ruby2/trunk/development/software/releases/wca/bootloader/20151127\_1.0.0.0/wca\_bootloader\_R262144.elf.p.S}{here}.\\
+The flash procedure has changed slightly. Because we don't have any longer
+the $TEL\_ON$ signal now the bootloader stays in bootloader mode for $t=2s$
+after switching on WCA. Within that period the bootloader accepts the
+connect request of the pc-side flash tool. If that period expires without
+receiving the connect request the bootloader will start the WCA application.
+\section{Hardware modification}
+To connect the WCA's Debug interface you have to populate 2 wires (Rx, Tx)
+between WCA's Debug interface and RS232 level shifter.\\
+On WCA side the $UART\_RX$ has to be connected to free pad of resistor
+$R35$. $UART_\_TX$ has to be connected to free pad of resistor $R21$. For details see figure\ref{fig:photo} and \ref{fig:schematic}.
