Hello dear,

I've try to program an SPI flash from Macronix MX25V1635F and receive
the following mensage from flashrom:

Calibrating delay loop... OK.
Found Macronix flash chip "unknown Macronix SPI chip" (0 kB, SPI) on
ft2232_spi.
===
This flash part has status NOT WORKING 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 ***@flashrom.org if any of the above
operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -Vr,
-VE, -Vw), and mention which mainboard or programmer you tested.
Please mention your board in the subject line. Thanks for your help!
Read is not working on this chip. Aborting.

Can you help with this?

Thank you very much,

Best regards

Emiliano

Don't see that in the list of supported chips. You might have to add the
flash chip definition, but I'm not exactly sure how to do that...

There basically a big table in flashchips.c .

It's relatively easy to add new chips providing it is safe for Emiliano
to experiment (e.g. if flashrom does something "bad" it won't brick an
expensive board).

Basically look through the parts table looking for a chip that is
as similar as possible to the one you have and clone it, then work
through the datasheet updating the various fields. flashrom is coded
pretty defensively which helps... when I tried this it found several of
my mistakes during its initial sanity checks.
