In that > future, we use the very well characterized ext2 or ext3. but that doesn't help- as such we have our OS on "on-chip" flash. that's where it is. it's nastily slow (2mb/sec read rates is what i clocked on the mtdblock devices themselves, so bypassing jffs2 overhead). am i wrong i suspecting our flash SHOULD be much faster? (like 5-10x faster)? this is for freerunner. future devices is... another matter :) > - -Andy > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.9 (GNU/Linux) > Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org > > iEYEARECAAYFAkhzc44ACgkQOjLpvpq7dMqvnQCfTS85sDbNc952KW1qvyXbF6EQ > JgQAnig0wv29uOyl4PWjhP6yDphKH9Rc > =l9bc > -----END PGP SIGNATURE----- -- Carsten Haitzler (The Rasterman) <[EMAIL PROTECTED]>
