libflashrom rust binding
by Evan Benn 10 Aug '22

10 Aug '22

Hello flashrom, I have uploaded 2 CLs implementing a libflashrom rust binding: https://review.coreboot.org/c/flashrom/+/65280 https://review.coreboot.org/c/flashrom/+/65281 The first creates a bindgen (https://github.com/rust-lang/rust-bindgen) 'thin' binding generated from the header. The second creates a 'fat' binding, translating from more idiomatic rust into the libflashrom API calls. The fat binding is not complete, I have added only the parts I am using. I have also added the first user of the fat binding, flashrom-tester: https://review.coreboot.org/c/flashrom/+/65282 I think the first question is is the flashrom community happy to have these bindings live inside the flashrom git repo? They could live in their own separate repos, but keeping them with flashrom will make keeping up with libflashrom API changes more straightforward. Otherwise please review the implementation if you are interested. Thanks Evan Benn

Setting page size in AT45db081d spi flash
by rh100605＠aol.com 07 Aug '22

07 Aug '22

I have used Flashrom to backup a memory image in a radio using the AT45DB081E spi flash memory. The read operation worked well using the Flashrom device set as AT45DB081D I bought some more used AT45DB081E chips to write the saved image and Flashrom objected by stating that the image was too big by 32767 bytes I edited image by removing the last 32767 bytes and Flashrom wrote the used chips and verified successfully using the device setting AT45DB081D While reading the datasheet I noticed that the AT45DB081D/E has two page sizes 256 and 264 bytes which explains the 32767 bytes difference in image sizesIt seems FlashROM is aware of the page size setting! However I cannot see how read the status register to see the page size set or how to change it using the 0x3D 0x2A 0x80 0xA6 / A7 command as described in Chapter 11 of the AT45DB081E datasheet To summarise I want to change the page size of an AT45DB081E back to 264 to repair the radio and cannot see how to use Flashrom to do it RegardsRob

Restructure shutdown functions and remove global state
by Joursoir 05 Aug '22

05 Aug '22

Hello everyone, Today I had a first meeting with my mentor Anastasia. And I'm looking forward to see Thomas as soon as possible. We've discussed our project goals, initial tasks and current state of the code. My next tasks: 1) Move all par masters to new API. It includes reducing the use of static global variables by storing them in a specific programmer data structure. 2) Introduce default shutdown function that can be very useful. We already have a patch for it: https://review.coreboot.org/c/flashrom/+/54890 It will be done in small steps/commits. So I hope to send a first patch soon. -- Joursoir

Board confirmed: Supermicro X7SPA-H
by Jim MacKenzie 05 Aug '22

05 Aug '22

Hi all, New subscriber. The Supermicro X7SPA-HF board is listed as specifically allowing BIOS updates using flashrom. I can confirm that the Supermicro X7SPA-H board (which is similar but not identical) also works with flashrom. I used flashrom to update the BIOS from 1.2a to 1.2b earlier this week. I've also used it to update my PC Engines APU single-board computers, but this compatibility is already noted and in fact sanctioned by PC Engines as the best way of doing the coreboot update on this platform. Thanks! I'll be watching with interest. Jim

01 Aug '22

Hi, I'm trying to flash the rom of a bricked Chromebook. I've tried multiple times, removing and reattaching the ch341a. The rom chip is still attached to the motherboard (I've never soldered). Any help would be appreciated! Thanks, Jen jen@localhost:~> sudo ./flashrom -p ch341a_spi -w coreboot_tiano-candy-mrchromebox_20220704.rom flashrom v1.2-99-gfbb2b25f61 on Linux 5.14.21-150400.24.11-default (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found Winbond flash chip "W25Q64.W" (8192 kB, SPI) on ch341a_spi. Reading old flash chip contents... done. Erasing and writing flash chip... FAILED at 0x0000ef66!

flashrom dev meeting notes 28.07.22
by Felix Singer 29 Jul '22

29 Jul '22

# 28th July 2022, 6:00 - 7:00 UTC+0 Attendees: Thomas, Edward, Alex, Felix, Nikolai, Anastasia ## Decisions Summary * As a result of going through realtek_mst_i2c_spi few feature requests can be created for i2c infra (not release blocking). TODO aklm * We need to contact top5 distros that use flashrom because they will break after meson change is merged. TODO aklm to contact Gentoo first, TODO Thomas to contact others. ## Agenda * [quasisec] reminder that we should at some point soon have an end of week burn down of patches that look ready to merge and try and have a situation where authors are not merging their own patches and instead having a consensus merge window at the end of the week. This way we can all agree that at the time of merge everything was fine as far as we knew if anything came up later. * [aklm] Bugs for release “document this programmer”. Is there anything left to do, if yes then what is left? * (I_want_brick for programmer param for all i2c programmers already decided on the previous meeting, so everything else) * realtek_mst_i2c_spi [https://ticket.coreboot.org/issues/361](https://ticket.coreboot.org/issues/… (man page added) * Where do opcodes come from ? should this become opaque? Not blocking for release. TODO file bug (or change existing ticket to say “all i2c programmers should be opaque”.) * Abstract i2c interface to allow other OSes to work with i2c. TODO file a bug. Not release blocking. * Otherwise all good * Maybe we can make a programmer type “i2c” as a part of refactoring. * TODO For Peter: test the programmer works and close the ticket * Serial has global state * Nikolai: we need to know which chip we have * Upstream ichspi is opaque chip * We have another loop in our tree, which goes through flash chips and tries to find which chip it is. This is kind of re- implementing what is done on flashrom initialisation. There is no other way for ichspi opaque to expose how it reads chip id in opaque master. * Long term Thomas/Edward/Nick agree, one master with capabilities is a better pattern but this is a very large and complex change. * We can send the patch upstream! With good commit message * [https://ticket.coreboot.org/issues/376](https://ticket.coreboot.org/issues/… (it says review mediatek_i2c_spi) * Why are isp and debug ports shifted? It is unusual to shift from left to right () [https://github.com/flashrom/flashrom/blob/master/mediatek_i2c_spi.c#L29](ht… * We need to resolve the comment from original patch [https://review.coreboot.org/c/flashrom/+/61288](https://review.coreboot.org… * TODO aklm, get scout board to test the mediatek programmer * Assign bug to Peter * Needs to be tested and allow_brick merged, and then it is fine. * Edward: two phase project for future * Refactor board_enable.c , so that search logic separated out * (phase 0) GPIO logic moved out from board_enable.c into board_gpios.c here [https://review.coreboot.org/c/flashrom/+/66174/](https://review.coreboot.or… but that is a step towards the next step, * (phase 1) Move the `flash_enable` code into the programmer init so programmers are fully qualified. * (phase 2) Board_matches logic have entries for each supported programmer with their parameters * quasisec put all the board data in declarative JSON that is parsed and then fully qualifies the programmer at initialisation. * dmi probably needs some love, this is fine ;) .. * Thomas: What's with meson patch? We need to test [https://review.coreboot.org/c/flashrom/+/63724](https://review.coreboot.org… * Can break distros, we can maybe contact popular distros distros? * [Gentoo](https://packages.gentoo.org/packages/sys-apps/flashrom) * [Fedora](https://packages.fedoraproject.org/pkgs/flashrom/flashrom/) * [SUSE / openSUSE](https://build.opensuse.org/package/show/openSUSE:Factory/flashrom ) * [Ubuntu](https://packages.ubuntu.com/jammy/flashrom) * [Debian](https://packages.debian.org/bullseye/flashrom) * [openWRT](https://openwrt.org/packages/pkgdata/flashrom) * [Arch Linux](https://archlinux.org/packages/community/x86_64/flashrom/) * [Arch Linux ARM](https://archlinuxarm.org/packages/aarch64/flashrom) * [NixOS](https://search.nixos.org/packages?channel=22.05&from=0&size=50&sort=… ) * [Alpine](https://pkgs.alpinelinux.org/package/edge/main/x86_64/flashrom ) * aklm TODO contact Gentoo maintainer, because they also have ebuild * Felix: I already tested on NixOS. I am also the maintainer for flashrom in NixOS * Thomas: cmocka deps, most distros already have cmocka? We don’t need this subproject. I will make a patch to remove it. * FreeBSD needs testing and then enabling in meson build * Minimum versions for build system? We currently have only minimum versions in code, but not in the build system. * For package maintainers we need to say: this is required minimum version

flashrom maintainers
by Anastasia Klimchuk 27 Jul '22

Hello People, We just got a flashrom’s own MAINTAINERS file! I wanted to share the news with everyone. https://github.com/flashrom/flashrom/blob/master/MAINTAINERS There is a script which will automatically add people as reviewers to the patch, if the patch is touching the files/area they are “registered” for. This makes sure patches are not lost and also answers the question “who are the best reviewers for this patch?” Anyone else can join any code review (as usual, as it was before), but the people from the file will be added automatically. Is anyone interested in being a maintainer/reviewer? Maybe you know some specific area well, and/or maybe you don’t want to miss when a patch comes along and touches that area. “Area” can be just one programmer that you know well, and you can take it with “Odd Fixes” status - this is the smallest possible commitment, but still will be very useful for flashrom. Any area can have multiple maintainers. Also, MAINTAINERS file have some content already, but you can of course join the existing category if you are interested. What to do if you are interested? You can reply to this thread or just send a patch. I have some thoughts on what categories/areas we can have, but that’s my initial suggestion, it is not a complete list and everyone’s ideas are welcome. Many thanks! # Programmers In general, one programmer can be a category by itself. Some others can be grouped (for example we have an i2c group with 3 items). # Libflashrom (can be sub-category of Core) libflashrom* include/libflashrom* # Documentation Doxyfile README flashrom.8.tmpl # Core Flashrom.c Layout.c Jedec.c Opaque.c Spi.c Programmer.c Programmer_table.c Spi25.c Spi25_statusreg.c Spi95.c … and more files here, and headers # internal List of files here, also headers # Configs MAINTAINERS # Git (can be sub-category of Configs) .gitattributes .gitignore # Scripts *.sh util/*.nix util/*.sh #CLI cli* # Utils Manibuilder Flashrom_tester ubertest # Flashchips flashchips.c One file, but it has a constant stream of patches. Would be great to have someone keeping an eye on it. # Tests -- Anastasia.
