+By default, the disassemble command in GDB operates in ARM mode. The programs running on CORTEX-M3
+are compiled in THUMB mode. To correctly disassemble them under GDB, uses an odd address. For instance,
+if you want to disassemble the code at 0x20000000, use:\\
+\begin{small}
+\begin{lstlisting}[frame=tb]
+$> disassemble 0x20000001
+\end{lstlisting}
