To view the configured memory map in gdb, use the gdb command @option{info mem}
All other unasigned addresses within gdb are treated as RAM.
+GDB 6.8 and higher set any memory area not in the memory map as inaccessible,
+this can be changed to the old behaviour by using the following gdb command.
+@smallexample
+set mem inaccessible-by-default off
+@end smallexample
+
If @option{gdb_flash_program enable} is also used, gdb will be able to
program any flash memory using the vFlash interface.
