CONFIG_FS_FATFS_READ_ONLY

Read-only support for all volumes

Type: bool

Help

The option excludes write code from ELM FAT file system driver;
when selected, it no longer will be possible to write data on
the FAT FS.
If write support is not needed, enabling this flag will slightly
reduce application size.
This option translates to _FS_READONLY within ELM FAT file system
driver; it enables exclusion, from compilation, of write supporting
code.
