From the reversion I do, it looks the check-in of 6772 in uclist-dist of yaffs

result in this bug.

Does this checkin only affect yaffs?

 

--- Mingquan Pan                                             2008-06-19 04:24:11

I do the diff of 6771 and 6772,finding that:

+++ vendors/config/bfin/config.arch     (revision 6772)

And user/mtd-utils/mkfs.jffs2 diffs with user/mtd-utils/build/mkfs.jffs2, to

use the latter one doesn't make to work properly.

if that's the case, i'll take a look

 

--- Mike Frysinger                                           2008-06-20 11:19:39

should be fixed in svn now

 

--- Mingquan Pan                                             2008-06-23 00:05:17

Yes.Close.
