Hello all,

currently I'm trying to familiarise oneself with the YAFFS2 concepts,
especially
the idea, how to accomplish the sequential write restriction of future FLASH
chips.

YAFFS2 uses a 4 byte sequence number to differ older chunks from the latest
one.
This really allows a lot of Blocks to be written, but how does YAFFS handle
a sequence number overflow?

On a 512MB FLASH memory this will surely happen
before reaching the FLASH limitations of about 100 000 Block rewrite
operations,
even with perfect wear leveling.

Is there a mechanism to prevent a sequence number overflow?

Thanks and best regards,
Martin.
