Why are you using such an ancient kernel version?  2.6.32 is 7
releases behind current, so it iis definitely a very bad idea to base
any recent development work on it.  Please update and use current code
instead.

Also, YAFFS2 is probably not the best choice for your system.
Unfortunately you don't provide any details - are we talking about NOR
or NAND flash?  How big is your flash device? etc.

Typically we recommend to use UBI / UBIFS these days - but you need
recent kernel code for that (or you might run into a number of bugs).

This may be because loading such big code and libraries from YAFFS2 is
slow.  For short boot times, other file systems are probably a better
choice.

Your questions are very generic and in no way actually ELDK related,
so you could have posted these on any f the more generic mailing lists
instead, for example on linux-embedded at vger.kernel.org

Best regards,
