I appreciate that it would be nice to have a simple "do 1,2,3 and note flash is
borked". Sadly , as I said before, this has crept up on us over about 18mths of
usage. So, other than the information I have already provided about the usage
the board has seen, I can not give you precise steps to reproduce it.
I would be happy if we had a better knowledge of the cause. It may be avoidable.

Thanks , that may ultimately be the best solution technically. We'll have to
discuss shipping costs since , as you recall , we are in Europe.

I will emphasis that this board has only ever had stock ts kernels. IIRC it was
shipped with ts9 and we updated it some months later to ts11 .
We don't use any yaffs tools. The fs is basically the stock TSlinux fs with our
software added via ftp.
We have been working on moving to 2.6 but I reiterate that this has only been
via nfs with an nfs root fs. Up until now the MTD has never been mounted by the
2.6 kernel.
Mounting with an upto data kernel and yaffs code may be useful as a diagnostic
but I have been holding off on doing so to avoid falsifying any later tests. So
please let me know if there is anything specific information you want me to do
to get off the device.
best regards.
Jacques.
