[U-Boot] Writing a YAFFS image to NAND

[U-Boot] Writing a YAFFS image to NAND

[Peter Barada]

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?

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.

Thanks in advance!

Not that I know of (unless something in cmd_yaffs2.c can do it).

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:

here's an updated patch for 2009.03, but i dont think it'll work with latest
master due to all the oob stuff being dropped ?
