I guess the picture doesn't matter much as this might be a software

Hi, I'm trying to write to a MX25L6473E using a raspberry pi and the latest
flashrom. I'm able to read correctly each time but writing fails.

I have attached below the cable setup I'm using.
Using this cable from Chipset pro to connect to the hirose 12 pin EFI
connector on the macbook pro.

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).

Uh oh. Erase/write failed. Checking if anything has changed.

Good, writing to the flash chip apparently didn't do anything.
Please check the connections (especially those to write protection pins)
between
the programmer and the flash chip. If you think the error is caused by
flashrom
please report this to the mailing list at [e-mail] or on IRC
(see
https://www.flashrom.org/Contact for details), thanks!
