Hi again,
I've got YAFFS working for a while with MTD under Linux 2.4, but
suddenly it stopped working, and I can't figure out why. I'm pretty
sure it's not an incompatibility problem with MTD since that was fixed
a while back. Anyway, the test setup is that I create a small
partition, erase it, mount, create one small file, unmount, mount
again, and the file is gone. I've enabled complete logging in YAFFS.
This is why I set the partition so small, to minimize the log file
size, but the same problem occurs with a larger partition as well.
I'm hoping somebody might be able to spot the problem real quick just
by scanning through the log below. There is one message that is
suspicious to me ("Chunk -1 not found zero instead") but may it is the
problem and maybe not.
The "debug1/debug2" statements are logging code I added around lines 4622/4654
in yaffs_guts.c:
{
char name[YAFFS_MAX_NAME_LENGTH+1];
yaffs_GetObjectName(in, name, YAFFS_MAX_NAME_LENGTH + 1);
T(YAFFS_TRACE_ALWAYS, (TSTR("debug1:(id=%X) -> %p (%s)"
TENDSTR),tags.objectId,in,name));
}
I noticed that yaffs_GetObjectName is creating a yaffs_Object but is
not setting its chunk number, so it stays at -1, apparently
permanently. Then when it later goes to look up the file for
yaffs_GetObjectName that is why it is setting the name to obj%d. I
tried adding a line to set it to tags.chunkId above, but that didn't
fix the problem and caused a kernel panic later on, so I guess I don't
fully understand what's going on.
Anyway, here's the log...
