Charles,
The YAFFS2 image I downloaded via git last week is encountering the same
problem behavior as the original version we were using.
WORKS - Small copies under 4MBs, NAND<>NAND, (both for the original version
and the latest version).
COPYING OVER 4MB FAILS - Larger copies consistently encounter an error
(failing about 95% of the time - although not always at the same place and
on a rare occasion completes).
--- I'm testing with an ~8MB file andusing the latest YAFFS2 code.
--- Adding printk and/or enabling tracing alters the failure point.
--- The destination file is partially being copied. Then the system oops at
times while outside of a YAFFS read routine and at times while it's inside a
YAFFS read routine (attached is one representative log snapshot).
Any insight or suggestion as to what direction to investigate would be
appreciated.
Oner

That is pretty old.
Please try the latest from git and see if you still get problems.
