Victor, Thank you so much for the datasheets! I did a review of the pending patch, and now it will be possible to finally finish the patch from 2021 and get the chips submitted. Also thank you for attaching the log. Not sure if the log is complete? It ends at the start of the reading operation, but there is no final message of SUCCESS or FAIL. However, importantly, I could see in the beginning of the log which platform was detected, and it is Promontory. Which means... Avinash, Most likely you are hitting a known issue, you can read more details here: https://ticket.coreboot.org/issues/370 The issue is for Promontory, and also for chips larger than 16Mbyte: which is exactly what you have. I was actually trying to get help from AMD with this issue, so it's really good to have you here on the mailing list! Maybe you can help? Someone from AMD would be in the best position to fix Promontory, you have all the datasheets available, and all the hardware. Thank you!

release v1.4.0 plan and timeline
by Anastasia Klimchuk 11 Jul '24

11 Jul '24

Good day everyone, We are preparing to do v1.4.0 release and below is the plan and timeline. TLDR: The release will be from the main branch. Testing and bug fixing window is from 28 June to 26 July, any help is highly appreciated! https://flashrom.org/how_to_support_flashrom.html#building-and-testing Known issue: https://ticket.coreboot.org/issues/370 More details: #1 In two weeks, on 28 June, we update the VERSION file to 1.4.0-rc1 and put a tag v1.4.0-rc1 (which means the first release candidate). From that moment, we open a 4-weeks window for testing and bugfixing. That is from 28 June to 26 July. During this window, bug fixes will be reviewed and submitted, but things like new features/refactorings etc will need to wait until 26 July. Just to be clear, any patch with new feature can be pushed and reviewed, it just won't be submitted until 26 July. Any help is very much appreciated during this time. #2 If needed, we can create v1.4.0-rc2 during the window #3 On 26 July, we update the VERSION file to 1.4.0 and put a tag v1.4.0 Then, there will be an announcement about the release, with the link to full release notes. After all that, VERSION file will be updated to 1.5.0-devel, all the patches that are ready and have been waiting, will be submitted, and everything gets back to normal. If later a point release is needed, it will be branched from v1.4.0 tag. Also, we plan to do another release later this year. So everything that didn't get submitted until 28 June (and by this didn't get into 1.4), can get into 1.5 later this year. Note there is a known issue: https://ticket.coreboot.org/issues/370 -- Anastasia.

flashrom dev meeting notes 27.06.2024
by Anastasia Klimchuk 02 Jul '24

02 Jul '24

# 27th June 2024, 6:00-7:00 UTC+0 https://ticket.coreboot.org/issues/542 https://ticket.coreboot.org/issues/543 https://ticket.coreboot.org/issues/545 Attendees: Joursoir, Anastasia ## Agenda * As the time goes, chip vendors are producing newer models, which sometimes re-use model IDs of old versions. Old versions are considered as "end of life", and replaced with newer models with more features. However flashchips.c accumulates everything and with time we get more and more duplicate model IDs. This makes adding new models harder, but also increases the chance users need to manually specify the chip model. Question: How can we avoid old chip models dragging down adding new ones, without completely removing them from the database (some users might still be using end-of-life chips)? * probably wasn't an issue 20 years ago when flashchips.c was designed, but now it is * have a flag "end of life" for chip definition? by default, given multiple definitions of the same model ID, the definition without a flag be selected? * vendors adding new model can mark old one end-of-life, in the same patch * [joursoir] It doesn't bother me. maybe it's not a big problem? but just having a flag "end-of-life" for information might be useful * need to be a good clear name, because flashrom still supports everything! * separate file flashchips_legacy.c for old chips? * bad: moving definitions from one file to another is pita * CONCLUSION: maybe we can add a flag to flashchip struct and no changes to probing logic yet. * ticket: [https://ticket.coreboot.org/issues/542](https://ticket.coreboot.org/issues/… * non-SPI chips are rarely used, and need special treatment in many places in the code. The code for non-SPI (flashchips definitions, parallel programmers, pieces of core logic) hasn't been updated or maintained for many years, So there are no new chips added or new features to the programmers. * maybe we can create a separate repo "flashrom-non-spi" with all the code. it will probably have 1 commit a year, or even less. The rest of code (SPI and PROG) will be simplified, better tested and can add new modern features * it will be too confusing for users, they might not know what they have, SPI or not * two binaries is confusing too * CONCLUSION: this idea is too wild, don't do this * [joursoir] It would be nice to have a pretty table of supported chips (like we had on the old wiki) on our website. Right now, there's flashrom option that prints chips in html format, however we need to rewrite it to rst so sphinx can use it. are there any pitfalls? * we can do 2-step process: one step generates .rst file (logic can be based on print.c), second step is normal build with documentation, and sphinx will generate html file for the website. * we can generate and publish html page with supported devices for the latest release. * developers who are interested what is supported at head, can look into source code or run `flashrom -L` . no need to generate html between releases. * [joursoir] I will do it! * ticket: [https://ticket.coreboot.org/issues/543](https://ticket.coreboot.org/issues/… * How about, we split our large file flashchips.c into smaller files, per manufacturer? * seems like a good idea * smaller files can get different maintainers per file => easier to get attention to your patch for flashchip * less merge conflicts * easier to find chips, easier to maintain * for example, const struct flashchip flashchips[] = { #include "chips/gigadevice.inc" #include "chips/macronix.inc" #include "chips/winbond.inc" } .inc is not valid c file, just a piece of code (slice array) another idea can be array of .c files * ticket: [https://ticket.coreboot.org/issues/545](https://ticket.coreboot.org/issues/… -- Anastasia.

FCH device found but SMBus revision 0x71 does not match known values
by tihmstar 25 Jun '24

25 Jun '24

Hi i have a QNAP TS-H1677AXU-RP-R7-32G NAS and i'm running a very unsupported config. I installed my own linux on it and somehow managed to enable secureboot, even though the bios doesn't have any settings regarding that. I would like to also enable TPM (from my understanding the installed AMD Ryzen 7 7700 should have fTPM?), but BIOS doesn't have any options about that either. It's weird, because the mainboard even has a dedicated TPM slot for external TPM. On further research i found this article https://ristovski.github.io/posts/inside-insydeh2o/ mentioning flashrom tool for dumping bios. I tried it but no success. It did say to send you an email, so here you go. Maybe you can help me with my journey to dump my bios? If nothing else, maybe the attached log is helpful to you. Cheers tihmstar

FAILED: juniper router

I have previously backed up the bios and am attempting to erase it, and am left in an "unknown" state. My desire is to successfully execute the erase. I am constrained from physically disassembling the mx204 router to confirm the board and chip. Multiple flash chip definitions match the detected chip(s): "MX25L12805D", "MX25L12833F", "MX25L12835F/MX25L12873F", "MX25L12845E/MX25L12865E", "MX25L12850F" I tried doing wp-status on all of them, and all responded "Cannot read SECURITY: unsupported by chip" except for "MX25L12850F" which responded: Protection range: start=0x00000000 length=0x00000000 (none) Protection mode: disabled node:/var/tmp/fw/x86_64-linux-gnu/sbin# ./flashrom -p internal:laptop=this_is_not_a_laptop -c "MX25L12850F" --ifd -i bios --erase -noverify-all --force -V flashrom 1.4.0-devel on Linux 5.2.60-rt15-LTS19 (x86_64) flashrom is free software, get the source code at https://flashrom.org flashrom was built with GCC 12.2.0, little endian Command line (11 args): ./flashrom -p internal:laptop=this_is_not_a_laptop -c MX25L12850F --ifd -i bios --erase -noverify-all --force -V Initializing internal programmer /sys/class/mtd/mtd0 does not exist No coreboot table found.

We could not detect this for sure because your vendor has not set up the SMBIOS tables correctly. Some internal buses have been disabled for safety reasons. You can enforce using all buses by adding -p internal:laptop=this_is_not_a_laptop to the command line, but please read the following warning if you are not sure. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and https://flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff.

Hello Rogier, I just checked, EN25Q128 is supported in the latest release 1.3, and from your logs you have 1.2 Is it possible for you to upgrade flashrom to the latest version?

Adding support for a new chip
by Jean-Baptiste Skutnik 07 Jun '24

Hello all, I broke my motherboard and flashrom would help me save 300$. I need to flash the BIOS chip and unfortunately, only the older version of the chip seems to be supported, so I would need to patch support in. The chip is the Winbond W25X40CL, which appears to be an upgrade over the W25X40 that flashrom supports. However, when hooking it up, the latter is detected and only the first 500K are available. I would need some guidance on what to do next. Looking through the gerrit I see the patches for new chip support add to flashchips.c and include/flashchips.h. Is there some documentation on what the fields represent in there so that I am not plugging randomly ? How does the process work when recognizing chips ? Would adding this chip create a conflict with its predecessor ? Thanks, JB
