Hello, While I was trying to internally flash the bios chip I step in this issue. I am nowhere near a programmer or computer literate, but I followed step by step the documentation. Are you familiar with this issue?

Fwd: Asrock B550M Pro4 -V and -VVV
by Nico Huber 23 May '24

Hi admkukuh, thanks for your report. It was stuck in the moderation queue because of the big images (not suited for a mailing list). Hence, I'm forwarding it without the images. It's amazing to see that the DOS port still works :) Did you also have to modify the stock BIOS to enable flashprog to read? Or was it only necessary to write? We could add a DEP (depends) entry to our list of known boards, I guess. Cheers, Nico -------- Forwarded Message -------- Subject: Asrock B550M Pro4 -V and -VVV Date: Wed, 22 May 2024 06:06:29 +0700 From: admkukuh <minecraftertamvan(a)gmail.com> To: flashprog(a)flashprog.org Below i attach success on B550 Chipset, i use B550M Pro4, but the stock bios needs to be modified, so i dump the bios chip that was flashed internally using asrock instant flash with the latest bios, dump it using programmer, remove AmdSpiRomProtectDXE from the bios, and Flashprog is able to read and write:[image: image.png] [image: image.png]

flashprog v1.1 -- our second feature release
by Nico Huber 03 May '24

03 May '24

Hi all, after a quiet week with the RC1, I'm happy to announce flashprog v1.1. This release brings a progress bar (--progress), support for Dediprog SF700 and SF600Plus-G2 programmers, and some more additions, fixes and tunings. You can find the full release notes on the wiki [1]. The code is available through the v1.1 tag and as a tarball [2]. Happy flashing, Nico [1] https://flashprog.org/wiki/Flashprog/v1.1 [2] https://flashprog.org/releases/flashprog-v1.1.tar.bz2

Preparing for new feature release with v1.1-rc1 | Please test!
by Nico Huber 26 Apr '24

26 Apr '24

Hi all, I'm glad to announce a new release candidate v1.1-rc1. 55 commits went into it, during a little more than four months. The most pro- minent changes are: * The `serprog' protocol now supports multiple CS lines. Which can be selected from the command line if the programmer supports it. * `serprog' driver now synchronizes more reliably after an aborted run and without the initial 1s delay. * We got rid of spurious attempts to memory map SPI flash chips by default. This was mostly visible with the `internal' programmer on AMD machines and `serprog' combined with big flash chips that just couldn't be mapped. * The CLI has a new `--progress' switch, finally(!) which makes it show progress bars for read/erase/write. Some programmer drivers were adapted to allow finer progress reporting. * The Dediprog SF600Plus-G2 (tested) and SF700 (untested) program- mers are supported now. And there were more, smaller changes and refactorings all over the place. As usual, the code is available through the tag `v1.1-rc1', and as tarball[1]. Please grab it! test it! Cheers, Nico [1] https://flashprog.org/releases/flashprog-v1.1-rc1.tar.bz2

Maintenance release v1.0.2-rc1
by Nico Huber 06 Apr '24

06 Apr '24

Hi, we found two regressions related to the Dediprog driver and large flash chips. There'll be a small maintenance release to fix them. The code of the release candidate is available through the tag `v1.0.2-rc1` and as a tarball[1]. Cheers, Nico [1] https://flashprog.org/releases/flashprog-v1.0.2-rc1.tar.bz2

[announce] Maintenance release v1.0.1 is ready
by Nico Huber 21 Jan '24

21 Jan '24

Hi, after a quiet test period, RC1 became the release. v1.0.1 fixes building our `linux_gpio_spi' driver with newer versions of libgpiod. Find more about it here: https://flashprog.org/wiki/Flashprog/v1.0.1 Cheers, Nico

Maintenance release v1.0.1-rc1
by Nico Huber 17 Jan '24

17 Jan '24

Hi all, flashprog has fallen behind with libgpiod compatibility. As it changed the API with version 2.0, which already ships with at least Fedora and ArchLinux. So we'll have a small maintenance release to include a new libgpiod bit-banging driver that uses the new API. The code is available through the tag `v1.0.1-rc1` and as a tarball[1]. As there are no other changes, only users of the linux_gpio_spi driver would have to test anything. Cheers, Nico [1] https://flashprog.org/releases/flashprog-v1.0.1-rc1.tar.bz2

[announce] First flashprog release is ready!
by Nico Huber 16 Dec '23

16 Dec '23

Hi all, I'm happy to announce flashprog v1.0, our very first release. See the full release notes[1] for more details and ways to download the source code. The most prominent change is the introduction of a new algorithm for erase-function selection from last year's GSoC. Which should provide a nice speed-up when operations are not limited by reading speed. Overall, this might be our fastest version so far :) Development already continued. A progress bar (finally!) and a CLI to control write-protection of SPI flashes are in the queue. Let's see what will make it into the next release. Best, Nico [1] https://flashprog.org/wiki/Flashprog/v1.0

[announce] First flashprog release candidate is there!
by Nico Huber 08 Dec '23

08 Dec '23

Hi all, glad to announce that the first flashprog release candidate is tagged :) Biggest change since flashrom-stable v1.1 is the integration of Aarya's 2022 GSoC work: a new core algorithm for the erase-function selection. Otherwise, a small workaround to avoid MTD as internal programmer on x86 was merged, beside a few smaller cosmetic and build related things. We'll let the ink on the RC dry for at least three days. You are of course encouraged to test it with your flashing setup, especially with the internal programmer. But keep a backup, so if something goes wrong, you can recover with an older version. The source code is available through the usual channels, on GitHub: https://github.com/SourceArcade/flashprog/releases/tag/v1.0-rc1 and of course in the main Git repo https://review.sourcearcade.org/plugins/gitiles/flashprog/+/refs/tags/v1.0-… Tarballs can also be downloaded here https://flashprog.org/releases/ Cheers, Nico
