FlashRom error report
by 이준기 15 Jun '22

15 Jun '22

Hello. I'm Junki Lee and I'm using a translator, so please understand. I used flashrom on my laptop and it gave me an error. ubuntu@ubuntu:~/Documents$ sudo flashrom --programmer ch341a_spi -w X5BF.B08 -c MX25L6406E/MX25L6408E flashrom v1.2 on Linux 5.13.0-30-generic (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 Macronix flash chip "MX25L6406E/MX25L6408E" (8192 kB, SPI) on ch341a_spi. Reading old flash chip contents... done. Erasing and writing flash chip... Erase/write done. Verifying flash... FAILED at 0x0004801f! Expected=0x32, Found=0x22, failed byte count from 0x00000000-0x007fffff: 0x3c5a Your flash chip is in an unknown state. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks! The model name of the laptop is Aorus X5.(https://www.gigabyte.com/Laptop/X5) CH341A was used as equipment. The name of the EEPROM is MX25L6406E from Macronix. The rom file used was downloaded from the link above. I've used flashrom several times, but the error was almost the same. It was always the same up to the failed byte 0x007fffff part, only the hexadecimal number after it was slightly different. I also tried CH341A programmer and AsProgrammer. Tried with multiple versions, same error as above. The delete worked fine, but the write operation always throws an error. My laptop is bricked. Can you help me?

Refactor arguments parser - GSOC project thread
by Chinmay Lonkar 10 Jun '22

10 Jun '22

Hello, Today I had a meeting with my mentors Felix and Anastasia. The project plan has been broken into phases. I'll work on the first phase, which will entail creating an alternative to extract_programmer_param() that will parse the programmer's sub-arguments according to the data type in which they have to be utilized in the code. So, I'll be reading through the code and working out a solution for this task, as well as analyzing all of the other parameters that the programmers utilize. Regards, Chinmay Lonkar

Verify problem with W25Q256JVEQ
by Mathieu Othacehe 08 Jun '22

08 Jun '22

Hello, I am trying to flash a Winbond 25Q256JVEQ with a dediprog programmer. The W25Q256JVEQ flash is put in a WSON8 socket. The socket pins are directly wired to the dediprog. The chip is detected and can be erased. However, the verification always fail this way: --8<---------------cut here---------------start------------->8--- Found Winbond flash chip "W25Q256.V" (32768 kB, SPI) on dediprog. Chip status register is 0x00. ... Found Winbond flash chip "W25Q256.V" (32768 kB, SPI). This chip may contain one-time programmable memory. flashrom cannot read and may never be able to write it, hence it may not be able to completely clone the contents of this chip (see man page for details). Reading old flash chip contents... done. Erasing and writing flash chip... Trying erase function 0... 0x000000-0x000fff:EW Erase/write done. Verifying flash... FAILED at 0x00000000! Expected=0x71, Found=0xff, failed byte count from 0x00000000-0x01ffffff: 0x268 Your flash chip is in an unknown state. --8<---------------cut here---------------end--------------->8--- I tried to add a 0.1uF decoupling resistor on VCC as well as pull-ups on CS, WP and HOLD pins and pull down on CLK as proposed in the "Winbond SPI NOR Flash Device APPLICATION NOTE", without any progress. I tried several W25Q256JVEQ flash memories and always observed the same behaviour. Any idea what could be wrong? Thanks, Mathieu

flashrom dev meeting notes 2.06.22
by Felix Singer 03 Jun '22

03 Jun '22

# 2nd June 2022, 6:00 - 7:00 am UTC+0 Attendees: Felix Singer, Chinmay Lonkar, Edward O’Callaghan, Joursoir, Anastasia Klimchuk, Nikolai Artemiev, Evan Benn, Aarya Chaumal, Thomas Heijligen, Arthur Heymans ## Decisions Summary * We want to look into git hooks and build bot scripts which check the code style for compliance. Discussion thread will be opened on the mailing list. * We want to renew the flashrom website and we will look into static site generators. Discussion thread will be opened on the mailing list. ## Agenda * [aklm] Welcome our students! * Aarya * Chinmay * Joursoir * [aklm] We have people from 3 software companies here, and also independent developers. This makes 4 parties, each one is using flashrom in their own ways, each one has some critical use cases. Can we talk and describe to each other how we use flashrom, what are critical use cases (unless it’s confidential)? My main goal is that we have more understanding (and maybe more patience) of each other’s work. * Servers: LinuxBoot, e.g. for updating CrOS-style `vpd` variables. This usually necessitates static binaries which are currently quite large (>1MB). Short of re-writing relevant bits of Flashrom (e.g. in Go), is there a good way to shrink the flashrom binary size? Some users are compiling with musl, for example: [https://github.com/flashrom/flashrom/pull/155](https://github.com/flashrom/… * How to make binary smaller * [quasisec] * Convert flash chips. C into parseable database * Make more parts of flashrom as re-usable units - i.e., modularity, remove globals etc. * Reduce binary size via build system changes * Removing globals plays into this, it adds more modularity * Edward: Chrome OS uses flashrom to update EC and AP. There are few other components that are updated with flashrom. We go through the internal path. Main programmers are ichspi, sb600spi, linux_mtd. * Thomas: (from Simon) Making things with FPGA , nothing to do with coreboot. Completely writing the whole flash chips. * Flashrom is Swiss army knife * Thomas (Secunet) : Development of coreboot, external programmer to read/write chip. Internal programmer for spi. libflashrom on the payload base. * [FelixS] coreboot uses a git-hook to run clang-format stylecheck. Should we use it too? * [https://review.coreboot.org/c/flashrom/+/43602](https://review.coreboot.org… * The script aborts the creation of a commit if the changed code doesn’t comply with the style guidelines. * We need to add make target * Is the check-style script blocking? What if false-positives appear? * Maybe another target on the build bot? Comments are added into Gerrit patch. * Script will run on git commit, locally * Arthur: I tried to make coreboot tree consistent, but clang choked on this, had a runtime. ~1 month ago I was trying this. * Thomas : data structures can be hard to format, like flashchip.c * We can put exceptions in the tool, so that formatting is not touched. * Arthur: We can just try, have a play with it and maybe it works in the tree? * It is hard to configure for parts of file, usually whole file or nothing. * First step can be a page on the build bot, which is not blocking. Second step adding comments to gerrit. * The patch will install a hook with make, meson is not adding a hook at the moment. * TODO start a topic on the mailing list * [FelixS] Should we use a tool for code formatting? * uncrustify: [https://review.coreboot.org/c/flashrom/+/42556](https://review.coreboot.org… * clang-format: [https://review.coreboot.org/c/flashrom/+/38673](https://review.coreboot.org… * Arthur: Uncrisfity works on coreboot * quasisec@: I one word: Yes. * quasisec@: Actually we can go beyond syntax checking and perhaps add: * Scan-build as a buildbot target to check for possible bugs (overflows etc) * Also coccinelle semantic patching for common bad or good patterns that should be applied. https://www.kernel.org/doc/html/v4.14/dev-tools/coccinelle.html * [FelixS] Should we rework / rebuild / modernize the flashrom.org website? * The flashrom website looks like a site from the early 2000’s. That’s not very attractive for potential interested people. The site should be replaced with something which looks modern. * quasisec@ needs more shiny! :D * Static site generators are easy to manage, they reduce maintenance burden (e.g. less or no updates) and also the risk for server-side security issues. * quasisec@ +1, also easy for the community to check in changes under review. All just markdown. * FelixS: More democratic to make changes for the wider community. * quasisec@ suggestions: * [https://www.getzola.org/](https://www.getzola.org/) also, * [https://jaspervdj.be/hakyll/](https://jaspervdj.be/hakyll/) is fantastic. * Check out [https://jamstack.org/generators/](https://jamstack.org/generators/) * Furthermore, it makes hooking up Doxygen code documentation generation trivial. * We have to find out what we need and which framework supports what. Then, various frameworks need to be evaluated and we need a plan on how to migrate to the new site. * [aklm] how do we build a knowledge base for users? Ideally such that users can update content themselves? * TODO start thread on mailing list * aklm: Wiki has 33 users, but wiki is rarely updated * Chinmay: There is a tool docsify. Lots of themes, or you can make your own theme. I can show an example? Yes! * Thomas: we need to make a list of requirements * There is some C code which generates wiki markdown with the list of chips. It needs to be run manually. It can be run on buildbot. * Mediawiki edit page says “Please note that all contributions to flashrom may be edited, altered, or removed by other contributors. If you do not want your writing to be edited mercilessly, then do not submit it here. You are also promising us that you wrote this yourself, or copied it from a public domain or similar free resource (see [flashrom:Copyrights](https://www.flashrom.org/index.php?title=flashrom:Copy… ) for details).

Spansion S25FL128L readout
by Hilco de Lathouder 31 May '22

31 May '22

Hi All, I have a Spansion chip I want to read but it seems not supported by flashrom. I can connect and read JEDEC ID with BusPirate: it says 01-60-18 which corresponds with the Spansion S25FL128L (specs available online). Flashrom does not detect it. I tried reading it while forcing any of the other 128Mbit Spansion chips, but could not make anything of the rom with Binwalk. What would be the best strategy to get to the contents of this chip? Thanks in advance, Hilco

Decision making process
by Anastasia Klimchuk 30 May '22

30 May '22

Hello People, The topic initially came up in the “Gatekeeping” thread. However it was suggested that it should be a separate thread, which makes sense so I am starting one. So, straight to the point: it looks like we have a decision making process emerging! (below). What do people think about it? #1 Discuss things on the mailing list first. It could be ongoing for months - so that everyone who is interested has time to read and respond. However, it doesn’t have to be for months. #2 When/if the discussion seems to be settled and people are in agreement, the item can be added to the agenda of the meeting. #3 At the meeting the item can be discussed again, and a decision can be made (or not made, if people disagree). #4 After the meeting we send an email with meeting notes and “Decisions summary” on the top of the email. #5 Since stuff never gets done immediately, there always be some time to react on #4 If someone has objections/concerns, it would be great if you can propose improvements or alternative solutions. Please don’t just say “this is all wrong!” Many thanks for sharing your thoughts! -- Anastasia.
