We got a mail by a reporter who does not want to get his email address published, therefore I will quote his email verbatim below.
I can confirm that I have just successfully flashed an ST 25P10VP flash chip, in circuit, using a Raspberry Pi, its onboard SPI, a Pomona 5250 SOIC clip and some female jumper wires.
I updated the Raspberry Pi B+ with rpi-update to the latest firmware and kernel, and compiled the code from svn://flashrom.org/flashrom/trunk on the Raspberry device itself. I just used the -p and -w parameters to make this work, no other magic. Flashrom reported write success and verified status on the chip.
According to Micron documentation, the markings 25P10VP correspond to a M25P10-A, and flashrom recognizes this type indeed. Since the status for writing this chip is still a question mark, I thought I should report a success.
I encountered zero errors during the use of flashrom, everything worked in one go. Flashrom allowed me to recover a friend's WD HDD with a burnt-out PCB. So a big thank you is in order!
Thank you so much!
P.S. Could you please keep my e-mail address private?
Kind regards, Martijn Schiedon
I'll add the respective flag for the M25P10-A. Thanks Martijn for the report! Please include a verbose log file next time.
