JFFS2 only operates with a single sector size. However, when you have smaller erase blocks you will generally find that they add up to a single block's worth of the normal erase size. For example, 8*8KiB + 15*64KiB. JFFS2 will work OK on that, and just treat the 8*8KiB blocks as a single 64KiB block. -- dwmw2
