91 The ROMFS option 'CYGNUM_FS_ROM_BASE_ADDRESS' needs to be set to this
92 value in order to access the filesystem.
93
94 91
92 This address can then be used in your program in order to mount the
93 filesystem.
94
95 For example, to automatically mount the new romfs created above at
96 /rom, you can use the following macro in your application:
97
98 MTAB_ENTRY( romfs_mte1,
99 "/rom",
100 "romfs",
101 "",
102 (CYG_ADDRWORD) 0x50040000 );
103
104 See the File I/O package documentation in the eCos Reference Manual
105 ("Writing a New Filesystem") for more information about the MTAB_ENTRY
106 macro.
107
108 Alternatively, the filesystem can be dynamically mounted with a call
109 to mount() such as the following:
110
111 err = mount( "0x50040000", "/rom", "romfs" );
