AT45DB011D read not working

[The Raven]

Read is not working, other things (yet) not tested.
See log for details.
It ends with a "Speicherzugriffsfehler" which means "Segmentation fault".
I can do more tests if needed. Tell me what you need. :-)

Hi there,

that's probably my fault but I had no time to review the proposed fix
yet. Take a look at http://patchwork.coreboot.org/patch/4107/ please.

Tested and it seems to work!!! :-)
Read works, other not tested.
I don't like to test erase and write with this chip, but i search for
another
AT45DB011D to do this tests and report.
Strange that this error only happens on 011D and not on 161D.

Can you please commit this patch?

THX and greetings

Ok, have made some more tests (with patched version).
Think read and write works, but erase not. Look for me like a dump or
something.
Attached logs.

Hope it helps :-)

Tested with "flashrom v0.9.7-r1796".
Chip is still "UNTESTED" for all operations, but probe, read, erase and
write works.
Tested many times with random data. Always ok.

I also tested the erase functions:
Function 0 -> ok
Function 1 -> ok
Function 3 -> Not OK!

The output is:
Found Atmel flash chip "AT45DB021D" (264 kB, SPI).
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).

This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to [e-mail] if any of the above

work correctly for you with this flash part. Please include the flashrom

Actually... your data in this log does not require an erase cycle,
that's why it *looks* like working... because it just writes (but does
not erase).

I have checked the eraser definitions of the chip and they look fine. 
Therefore I have marked the flash chip as fully tested and will commit
that later together with other small changes.

Ha found again two "AT45DB011D" chips on a system board.
You can found many many "AT45DB011B" chips, but the "D" is very rare!
To bad that the "B" has no probe function and can not be supported by
flashrom.

Anyway, here are the results for the "D" with latest flashrom:

Probe: OK
Read: OK
Erase: OK
Write: OK

So i think this chip can be marked as supported.

I have attached the logs.

If you need more testing or logs -> Tell me what you need.

THX and Greetings

Hello,

thanks for your report!
I have marked the flash chip as fully tested and will commit that later
together with other small changes.
The chips without ID opcodes might be supported in the future so please
dont throw all of them away ;)

Sounds good! :-)
Some of them (the AT45DB011B for example) can be found very very often.
So it would be nice if we can force reading and programming with -f
option (without guarantee of course).
I keep it and if something changes let me know. ;-)

BTW: I have an AT45DB161E here which has the same device ID like the "D"
(id1 0x1f, id2 0x2600).
