Hello
My pull request has already been created that had occurred *several months*
previously. I added support for ST 95XXX chips . The following chipsets
have been successfully tested for read, erase and write operations: ST [
95080, 95160, 95320, 95640, 95128, 95256 ]. I would like to discuss a new
features.
Maybe someone in the community will spent a bit of time and review my pull
request. Don't worry about the conflicting files. The part of the code has
already been merged into effect.
*I'm open-minded and ready. *
Try to shorten the wires between SOIC8 and CH341A and/or replace them
with the copper ones, maybe that would help.

I tried with -f and it seems part of the bios chip is actually locked. The laptop still boots properly and I can install Windows on it but cannot change any of the bios settings as the TPM is preventing me to manipulate it. I mean it is not too bad these units are going into the resale channel but not the one with the locked bios. I will see if there are any samples, and if I am successful I will upload my process.

I've had success flashing internally on a C232 chipset, an ASUS P10S-I
motherboard with a partially working in-progress coreboot port.
flashrom picks it up as an opaque chip when flashing internally. It's a
W25Q128.V according to the ch341a.
Output attached.

Hi,
I would like to thank you for development of the flashrom tool, as I was
able to fix my bios via the tool.
The chip I have is gigadevice GD25B128C and I was able to use the settings
for GD25Q128C.
The software informed me that reading or writing to this chip wasn't tested
so I thought it would help to inform you that both functions worked for me.
Sencirely,
Omer basri
You haven't described what device you are trying to flash. Usually
there's nothing wrong with using SOIC8 test clip, for the laptops.
However, some routers/hdmi recorders/other devices of this type, may
try powering its' main CPU from a test clip and interfere with your
programming through a test clip. In example, here's a flashrom mod I
had to do for making it possible to read a firmware of one router
through a test clip https://review.coreboot.org/c/flashrom/+/31830
(because a CPU tries to power itself from a test clip and access a
flash chip, its' only available for 30% of each second to a programmer
behind a test clip), however - despite a similar code for read and
write - this router becomes software bricked if a write has been
attempted, and then a chip is inaccessible at all without a
desoldering.
So a chip itself could be fine, and such problems could be caused by
an imperfection in your device's hardware design. Other problems could
be i.e. too long cables between a SOIC8 test clip and a programmer, or
their poor quality (i.e. electrical resistance of aluminium wires is
about 1.5x times higher than of the copper ones with the same
properties).

So this happened: I forgot to Erase the EEPROM, which clearly is my fault, but it was late and I was tired.
Just trying to see if I can recover this EEprom at all or if I am better getting a couple of new ones from eBay?

Hi flashrom community!
Long time no see. Just want to report success on probe & read of
GigaDevice GD25Q40(B). The chip itself has different markings; 25Q41BT,
as in
https://ae01.alicdn.com/kf/HTB11jcQJVXXXXaeXVXXq6xXFXXXg/FREE-SHIPPING-SOP8…,
which points which is probably same or similar GigaDevice SPI flash (?)...
The chip is found on PowerColor RX5700 ITX graphics card, and according
to the read ROM contents, reading was successful.
I do not dare to try erasing/writing, as this card is too damn expensive
to risk it...
R,
S
