Hi,
I start driver as follows:
./devf-generic -s0,1M,2,1 -vvvv &
65551 running ./devf-generic

Flash is recognized properly and I am able to read data from it.
For example I copied whole 1MB partition (/dev/fs2p0) without any error.
During writing to flash I get the following message:
cp data.1 /dev/fs2p0
devf: over poll waiting for write completion in amd_v2wordwrite:97
cp: write (/dev/fs2p0): Input/output error
What does above error mean?
What I should to do next?
What part of driver or MTD library do I need to modify?
Regards,
Jacek
Maybe problem reside in fact that our flash has blocks at
different size (16k + 2x8k + 32k + 15x64k)?
It is possible to handle such device via devf-* driver?
Where and what should to be modified?
Until now I was playing with several flash devices, but all
of them had a constant size of block.

Jacek

That should not be a problem.
Check if the flash is write protected.
