[flashrom] Some test with arduino/serprog and different chips

[Raven]

Hello,
i made some test with the arduino/serprog and some different flash-chips:

*M25P16* -> all ok (erase and write has status "untested" but works ok!)
*M25P40* -> all ok
*W25X40* -> all ok

*25F512* -> erase not working, always same error:

*LE25FW406A* -> not supported! Can i do something to help you support
this chip?

*AT45DB161D* -> all ok, perfect work!
*
**AT45DB011B* -> not supported!
You said that this chip (B and earlier) has no identification support.
But i am not sure if this is relay true. Let me explain:
Years ago i build another programmer for the parallel port. Very cheap,
but not relay stable, or let's say very unstable! :-\
But the tool from this programmer is able to detect the chip:

And now i have a clean read from this flash and can test it with
flashrom ;-)
Maybe you can contact Adam Dybkowski and ask how it works.
This is/was the "Project-Page": http://dybkowski.net/content/en/node/15
And i also have his email if you need it.

Wish you a nice day!

Greetings
