JFFS2 problems on 32M AMD AM29LV128

[Linda Zhu]

Hi,

This is Linda. In our system, we run JFFS2 on AMD AM29LV128. We have total
32M
flash memory. It is partitioned into two part. First 1M memory is used by
loader,
the rest is used by JFFS2.

Originally, we use 16M flash. The JFFS2 run well on it. Recently, after we
increased the memory to 32M, we constantly encounter error messages as
indicated
below. If you can explain to me what these error messages mean, it is deeply
appreciated.

======================================================
The problems occurred when we login in from NFS, then tried to mount to
jffs2.
And then tried to copy a gz file from NFS file server to flash.

========================================================
The problem occurred when we login in with FLASH file system. Then tried to
copy
a 3M file from NFS server to flash. The copy couldn't complete, because the
writing
operation failed.

Please advice what might be the problem and how to resolve it.

Many many thanks,
Linda
