Thinkpad T420
by aadu＠airmail.cc 17 Mar '18

17 Mar '18

Hello I was trying to flash BIOS of Thinkpad T420 for my project when I noticed that version 1.0 of flashrom doesn't support it. From coreboot wiki I understood that it was supported at some point. Is there a way to bypass this or does older version of flashrom support it? Aadu

If you can flash internally from an OS depends mostly on the configu- ration of the chipset done by the BIOS. Likely only possible if there is an explicit option in the BIOS setup to disable flash protections. You can always try to run flashrom to see the actual configuration. Though, for mobile devices it needs an ugly switch (have a look for `force_I_want_a_brick` in the flashrom manual page). That switch sounds scary because older laptops really had problems, even if you only probed the flash chip. It's not that dangerous on a modern sys- tem. The alternative is to access the flash chip physically, like Mike described. If you get access to the flash chip, you'll also need a valid BIOS file (not just an update). > Starting from surface pro4 Chip is manufactured by Microsoft. What chip? never heard that Microsoft would manufacture chips. Nico

GD25Q128C write success
by Tomasz Walach 16 Mar '18

16 Mar '18

Hello, I have tried to recover my IP camera with flashrom and PI after I erased all memory. I think my successful reading writing and verifying of an image which I used might prove that this chip 25Q128CSIG is supported. As an attachment, I am adding 2 pictures of the camera and an output of log after writing procedure. If you need something more to test on this chip please let me know. Thank you very much for developing and allowing flashrom to be used by anyone. Without it, I had to find another way to write the image. At least by confirming the successful result, I will contribute this way in future development. Regards, Tomasz

tear down that surface, locate a BIOS chip on the motherboard, write down the markings on the chip and look through this page https://www.flashrom.org/Supported_hardware to see if your chip is supported by flashrom On Fri, Mar 16, 2018 at 3:08 AM, dsingh <dsingh(a)wavestek.com> wrote: > Any idea if this software can flash surface pro 4 BIOS? > > Starting from surface pro4 Chip is manufactured by Microsoft. > > Thank you > > Dharmpreet Singh > > _______________________________________________ > flashrom mailing list > flashrom(a)flashrom.org > https://mail.coreboot.org/mailman/listinfo/flashrom

Hi, I have an Spansion/ Cypress FL256SAIF00 (http://www.cypress.com/file/177966/download) , I'd like to write to. I added the diff to recognize the chip, but I believe I did something wrong- can you help? Regards, Michael!

[PATCH] Fix compilation with older MinGW versions
by Antonio Ospite 13 Mar '18

13 Mar '18

The __MINGW_PRINTF_FORMAT constant has been defined back in 2012 https://sourceforge.net/p/mingw-w64/mingw-w64/ci/77bc5d6103b5fb9f59fbddab15… However older toolchains are still around and some user reported the following compilation failure: flash.h:336:1: error: '__MINGW_PRINTF_FORMAT' is an unrecognized format function type [-Werror=format=] __attribute__((format(__MINGW_PRINTF_FORMAT, 2, 3))); Fix this by defining the constant when it isn't already; the change does not affect other compilers because it's guarded by "#ifdef __MINGW32__". Setting __MINGW_PRINTF_FORMAT to gnu_printf is exactly what newer MinGW versions do when __USE_MINGW_ANSI_STDIO is defined, which it is in flashrom Makefile.

Success report - Intel Broadwell U Premium
by Laurent Grimaud 07 Mar '18

07 Mar '18

Hi there, I just flashed my Gigabyte Brix GB-BXi7H-5500, Intel Broadwell U Premium, under Linux (debian sid), using flashrom v0.9.9-r1954 on Linux 4.15.0-1-amd64. Worked like a charm, I just needed to boot using iomem=relaxed. The chip is marked as "untested", hope this success report will help. Big thanx for the great job, please keep-on doing it ! -- Laurent
