Hi
I use this mechanism and I have no problems like what you describe. If you
would like to see a working example, look at the bootloader sources at
http://balloonboard.org/cgi-bin/viewcvs.cgi/balloon/branches/bootldr36-pxa-sa1100/
which is an implementation in current use.
I am afraid that your debug report of "not able to detect" is a little
sparse so I can't help more than that without any other information.
Please note taht mkyaffs2image makes an image suitable for 2k page size
nand and not for a 512 byte page size nand using yaffs2 in compatability
mode. For that you would use mkyaffsimage
Good luck
Nick
