build_fs failed

Wed Apr 24 21:53:32 EDT 2002

Sorry, I included the full log in a message last week but did not get any
answers so I tought I would ask a more precise question.  I am including it
below.  Here are some of the problems I had that I think could be relevent
in this case.

I am using a DiskOnChip 2000 of 32Mb with a 16K erase size ... but the
"mkfs.jffs2" utility enforces a minimum erase size of 64K.  So I removed the
piece of code that replaced any value < 64K from the source and recompile to
build my jffs2 image (but I had the same problem with the original version).

I had to do the same kind of modification to the nftl_format utility. The
nftl layer under ext2 worked perfectly afterward but I really need something
like jffs2 for my application.
