[announce] flashprog v1.5 released!
by Nico Huber 13 Feb '26

13 Feb '26

Hi all, happy to announce another flashprog release, v1.5! It's a smaller one, mostly bringing the AMD and Intel chipset support up to speed. There are, as usual, release notes [1], and of course you can down- load the source right away via Git [2] or as tarball [3]. Cheers, Nico [1] https://flashprog.org/wiki/Flashprog/v1.5 [2] https://github.com/SourceArcade/flashprog [3] https://flashprog.org/releases/flashprog-v1.5.tar.bz2

Fwd: Flashprog freezes during reading.

Forwarding without attached DS, it can be found here: https://www.fmsh.com/nvm/FM25W128_ds_eng.pdf -------- Forwarded Message -------- Subject: Flashprog freezes during reading. Date: Wed, 4 Feb 2026 14:29:22 +0100 From: Ivan Colavito <ivan.colavito(a)gmail.com> Reply-To: ivan.colavito(a)gmail.com To: flashprog(a)flashprog.org Good morning, I have a TopTon X2E motherboard with an N150 CPU whose Libreboot support has just been added. The internal flash of the Libreboot firmware using flashprog succeeded (flashprog wrote VERIFIED), but the PC no longer turns on (black screen and status LEDs on). I’m trying to flash the original factory firmware back, but flashprog won’t cooperate: it tries to read the contents of the EPROM but then freezes without giving errors, and it doesn’t produce any dump. I’m attaching the log file (created with -VV). I’ll add that the motherboard shows this serial number: BK-1264NP-4L-45G25***** and that the EPROM chip has this marking: FM25W128 2526I2G, which should correspond to the specifications document that I’m attaching. Flashprog says it doesn’t recognize it, but the basic operations should work anyway… so what could the problem be? How can I convince it to perform the flash? I’m using a Raspberry Pi Pico H with the flashser firmware provided by Libreboot for version 26.01 (just released and compatible with my motherboard) loaded onto it. Thank you very much!

AMD ROM Armor
by Nico Huber 26 Oct '25

26 Oct '25

Hi folks, I've written a small article about AMD ROM Armor [1], a new tech that basically hides the SPI flash controller on current AMD systems. Alas, it seems that AMD is pushing to not provide an opt-out for users :-/ This might limit flashprog support to systems with open-source firmware in the future. If anyone knows more about ROM Armor, please get in touch :) Cheers, Nico [1] https://icon.sourcearcade.org/posts/amd_firmware_reading/

Intel H170 on GA-H170-HD3 - reading 'PROBLEMS, continuing anyway'
by Franck 19 Aug '25

Hi, Tried to read bios from Gigabyte GA-H170-HD3. Flashprog reported 'PROBLEMS, continuing anyway'. Unsure if this means reading fully succeeded or not. FYI this motherboard has a dual bios. https://www.gigabyte.com/Motherboard/GA-H170-HD3-rev-10/ Attached are logs without & with verbose. Thanks, Franck Richter

chipset "Intel Q87" untested - write succeeded
by Franck 08 Aug '25

08 Aug '25

Hi, Many thanks for Flashprog. I could successfully flash a Dell OptiPlex 9020 using it, to install libreboot. Internal flashing under linux using debian package (from unstable) flashprog v1.4. As requested in 'Found chipset "Intel Q87" with PCI ID 8086:8c4e. This chipset is marked as untested. If you are using an up-to-date version of flashprog *and* were (not) able to successfully update your firmware with it, then please email a report to flashprog(a)flashprog.org including a verbose (-V) log.' please find attached the log for write, and also for read (of original Dell firmware, also internally done). Have a nice WE, Franck

Reading EEPROM contents was not a problem, But when erasing such error occurs. flashprog p1.3-3-g8a27db9 on Linux 6.1.0-31-amd64 (x86_64) flashprog is free software, get the source code at https://flashprog.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). serprog: Programmer name is "pico-serprog" Found Winbond flash chip "W25Q80.V" (1024 kB, SPI) on serprog. Erasing flash chip... FAILED at 0x00002005! Expected=0xff, Found=0xdd, failed byte count from 0x00000000-0x000fffff: 0x4b9 ERASE FAILED! FAILED! Your flash chip is in an unknown state. Please report this to the mailing list at flashprog(a)flashprog.org or on IRC (see https://www.flashprog.org/Contact for details), thanks! Any ideas?
