Possibly, yes.

The SD card won't present itself as a normal flash device. It has flash
_internally_ but you can't get at it directly -- you can only treat it
like a hard drive with 512-byte sectors. So you need to use the
'block2mtd' driver so that you can use it as an MTD device and use JFFS2
on it.
