Please read: http://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:spi_mmc
You need to enable default language support.

Glad that worked. I think it's a small oversight on the Wiki page -- it shows enabling ISO8859-1 as the default NLS language, but only shows enabling of CP437 as an available language. I'm not sure who has the ability to fix the Wiki though.

the exact NLS needed depends on the files that are on the disk ... should make a dedicated page for this information
