Hello Andrius, Could you please send a verbose log to the mailing list? If you run flashrom with additional argument "-o logfile.txt", that should do. Please have a look at the man page. :) You could also check out common problems (https://www.flashrom.org/Common_problems). Perhaps a write protection mode is in effect, which cannot be disabled on a software level? Is the WP# pin low? We could help you better with that log file. ;) Thank you :) Hatim On Tuesday 26 July 2016 10:05 PM, Andrius Montvydas wrote: > > hello, > > I had a bad bios flash, so i wanted to flash original bios using > flashrom but it failed. > I was using Raspberry Pi 3, bios chip is winbond W25Q64FW > > flashrom v0.9.9-r1954 on Linux 4.4.13-v7+ (armv7l) > flashrom is free software, get the source code at https://flashrom.org > > Calibrating delay loop...

[PATCH 0/4] Initial OTP/Security Register infrastructure

by Hatim Kanchwala

Hello, This set of patches should be applied on top of the previous patches (https://www.flashrom.org/pipermail/flashrom/2016-July/014717.html). Continuing with the major points from the previous mail (linked above), this patch should bring support for new infrastructure to quite a few more chips. OTP models for Eon, GigaDevice and Winbond are supported now. AMIC, Macronix and Spansion OTP models are scheduled for the next revision. I admit that the CLI may not be worded in the most optimum way, but that was a conscious decision so that it could be sorted out while review. Thank you for your time. I am looking forward to your feedback and having a discussion.

make sure that PIN WP and HOLD must pull up to vcc or use other spi flash test your circuit connect ok！！发自网易邮箱大师 On 07/27/2016 00:35, Andrius Montvydas wrote: hello, I had a bad bios flash, so i wanted to flash original bios using flashrom but it failed.

Flash went all well but MB doesn't boot anymore :)

by Pierre P

Dear Flashrom Team, As the title suggest, I flashed my old Asus M2V with coreboot but now it doesn't boot anymore. I'm guessing it has more to do with the coreboot rom than with the flashing procedure but I'd like to know if you had an idea to what could have caused this failure ? To flash the MB I used the following command : $ sudo flashrom -p internal -w <mycorebootrom> It successfully flashed a chip (ST something) which is a removable chip on the motherboard. So with this success I decided to reboot the computer but then nothing, screen stays black, no beeping, no keyboard light, only the hard drive led stays on permanently What I tested : I unplugged everything, FDD, HDD, cdrom drive, usb internal connectors, I only let inside the graphic card (a PCI-E Nvidia GF 6600GT) and a stick of RAM I tested with another PCI-E Nvidia card (I don't have any other brand to test with) and with multiple combination of RAM sticks (1, 2 sticks, dual channel slots or not, 512 MB and 2 GB) Now the only thing I could try I guess is remove the ST chip and flash it with an external programmer ? I backed up the original MB rom before flashing. I hope you'll have an idea on what went wrong, if not my next stop will be the coreboot team :) Anyway thanks a lot for your great work ! Best regards, Pierre

Hi Gentleman and Lady, Let's me introduce myself first. I am an engineer manager in Insyde Corp. I am investigating to use flashrom binary to develop flash tool for Intel Apollo lake/Broxton chipset. The Intel Apollo lake/Broxton chipset is not on supported hardware of flashrom yet ***Will Intel Broxton/Apollo lake chipset to be supported flash chips for flashrom?* Sincerely. -- Yulong Chang Insyde Software Corp. 13F, No.161, Sec. 2, MinSheng E.

[PATCH] Print lock register configuration for N25Q128

by Hatim Kanchwala

Hi, As discussed over IRC, please apply this patch over the latest stable branch of flashrom from https://github.com/flashrom/flashrom. This is a "hacked" solution and is certainly not merge-worthy in its current state. Patch description - When prettyprinting status register byte 1 of N25Q128 chip, also print least two significant bits of lock register for each 64 kB sector.
