Support for M50FLW080A
by Javier Bizcocho 26 Aug '23

26 Aug '23

Hello guys, I'm trying to flash a modded bios on my motherboard. The computer is a Dell SC1435 and the flash chip in question "M50FLW080A" is supported by the tool already, but just partially. It looks like it can read the bios, but when reading or erasing it always fails (and every now and then it even forces my PC to reboot). My server is running FreeBSD 13.1, but I've also tried with Ubuntu (same result). Even though it fails to erase / write the chip was never altered at all, so I wonder if there is any kind of protection on it. Is there any logs that I can extract from the tool itself? I'd like to avoid the need to de-soldering the chip in order to flash it :). Any thoughts? Thank you in advance, Javi.

New flashrom website
by Anastasia Klimchuk 28 Jul '23

28 Jul '23

Good day everyone, Good news for the good day: we are launching the new flashrom website! doc.flashrom.org At the moment it is available by the address doc.flashrom.org, but in the very near future (think of a few weeks) it will move to primary flashrom.org. The reason for this few weeks' interval is to check everything looks good and fix small things. After the new website moves to the primary address, the old wiki website moves to wiki.flashrom.org and will be locked for editing. Wiki will be available as view-only until we migrate all the content. New website is generated by sphinx from sources that are in the tree under doc/ directory. To add or update documentation, you need to send a patch as per usual dev process. Separate wiki account is no longer needed to update the documentation. Everything is set up so that after the patch is merged into documentation, it will appear on the website shortly after. There is a doc on how to add docs with more details: https://doc.flashrom.org/how_to_add_docs.html As you can see, the new website doesn't have all of the pages migrated from the old wiki yet. This is by the plan, we will migrate the pages gradually, hopefully within this year. Everyone is very welcome to join migrating the wiki pages to doc/ files! Especially if there is a page in wiki that you own and can verify the correctness of content. Thanks a lot to everyone who was working on the new website! The idea has been around for a while, and it is so cool to see it happening! -- Anastasia.

upgrading Development guidelines on the next meeting 27th Apr
by Anastasia Klimchuk 20 Jul '23

20 Jul '23

Hello, For anyone who is interested: on the next flashrom meeting 27th April we are brainstorming a new up-to-date version of Development guidelines. If you have ideas and a bit of energy to improve our Dev guidelines, you are welcome to join! The main goal is to make guidelines clear and understandable by new contributors. Which can mean re-writing confusing bits, removing out-dated bits, adding missing bits, and so on. I created a doc for brainstorming: https://docs.google.com/document/d/1GHwUiKAUlqXifzXh7hlMpfGe56cyFc8Udn8zsUt… Doc allows everyone to add comments / ideas. No account needed. Regardless whether you can or can't join the meeting, you are welcome to add ideas to the doc. Thank you! -- Anastasia.

some news
by Anastasia Klimchuk 12 Jul '23

12 Jul '23

Dear flashrom community, I have just banned Nico Huber from flashrom gerrit and mailing list. This is a result of what was happening on flashrom during the last ~3 years. Nico has a long track record of bullying other developers, attacking people on public channels (Gerrit and mailing list), writing long toxic comments which blocked other people's work, and lying in all public channels. During recent years, Nico was the reason why several talented and motivated contributors left the project. It is really sad (if not tragic) that a talented engineer, with a lot of technical knowledge and experience, annihilates all of that by being unable to work with other people, and by refusing to take advice and learn. As you all know, Nico now has his own fork (aka flashrom-stable) and I had some hope that he will focus on that and we will get back to normal, peaceful and constructive work. Unfortunately, Nico decided to make a comeback, and started adding himself to flashrom patches and commenting on patches. I do not accept bullying and lying, and I don't want this in the flashrom community. No amount of technical expertise justifies bullying other people and lying in public. This is my firm position. Thank you guys for everything -- Anastasia.

Acer Aspire 8730g (Nuvaton/Winstron WPCE755)
by celliwig＠nym.hush.com 02 Jun '23

02 Jun '23

Hi, This may be of help to someone (or not ;)! Following the request in the 'Laptops' section of the wiki to send in code, here's my attempt to implement an opaque programmer for the WPCE775. Obviously programmer_table.c/programmer.h need to be updated to reference the programmer, and the Makefile updated to actually build it. i8042 code is there to reset the KBC as the trackpad will go crazy after swapping the EC to Flash Update mode. This is very much a work in progress. It's only been used to write/erase a single sector so far. So use at YOUR OWN RISK!!! Some notes on extracting this from a phlash16 WPH file can be found here: https://github.com/Celliwig/Reverse-Engineering/tree/main/Acer/8730g Specifically the found WPCE775 commands: https://github.com/Celliwig/Reverse-Engineering/blob/main/Acer/8730g/wp-acc… Hope this helps somebody, Celliwig

# 25th May 2023, 6.00-7.00am UTC+0 Attendees: Stefan, Damien, Edward, Anastasia ## Decision summary * see notes ## Agenda * [aklm] What's left to branch 1.4 * ready to delete makefile? * only one windows programmer left, to build with meson * progress bar * feature is incomplete, we can add [experimental] to the manpage TODO * amd spi [https://review.coreboot.org/c/flashrom/+/65237](https://review.coreboot.org… * renaming chain from Martin goes first * Edward's chain goes after that * new erase stuff can be better tested * let's split ichspi into two * [aklm] What is our procedure to sign the release tarballs? The process for 1.3 was rather chaotic, better have a well-defined process. * aklm needs to create the key * next meeting we sign * [aklm] let's enable erase/write optimisations by default? DONE * I want to complete this test [https://review.coreboot.org/c/flashrom/+/67535](https://review.coreboot.org… * static bool use_legacy_erase_path = false breaks one unit test full_chip_erase_with_wp_dummyflasher_test_success -> FIXED * [heijligen] add Chromebook specific documentation * aklm: maybe we can collect the links to chromebook documentation pages which are publicly visible. It would be good to have a page on the website which is a collection of documentation specific to chromebooks. TODO aklm try to find out. * existing docs might be removed and re-written, so adding links won't work * we need to start a new page, and gradually add stuff * check what are the questions on the mailing list, the most common questions need to be documented first -- Anastasia.
