RealView Debugger searches several directories for board files, including the default file, rvdebug.brd. The search path the debugger uses is:

RealView Debugger searches all of these directories for workspace files and other configuration files. In particular, this is how *.bcd files are found. When two or more files with the same filename are found in more than one of the searched directories, then the first file that is found with that name is loaded, and any subsequent files with that name are ignored.
