Is there support in the 2009.03 version of U-boot to allow writing a YAFFS image created by mkyaffs2image to NAND, including the meta-data in the OOB?
Not that I know of (unless something in cmd_yaffs2.c can do it).
Looking over the nand write/read commands, they look to ignore the OOB data interleaved in the image (i.e. 2048+16 bytes per page for large-block NAND). I did see a patch from fmandarino on the list, but that doesn't look to be in the 2009.03 codebase.
That was several years ago; if someone wants to submit a proper patch against current u-boot (without the pre-2.6.18 support, or at least with the newer format being the default), I'll apply it. Better yet would be a more general mechanism whereby the user specifies how many OOB bytes are interleaved in the supplied image, without any specific knowledege of yaffs.
i'm in windows atm so i cant post a proper patch, but this link should be useful: http://blackfin.uclinux.org/git/?p=readonly-mirrors/u- boot.git;a=commitdiff;h=b71bce9d98776f4b5aeecfae151f8961a6ef8e98 -mike
