linux_spi - spispeed not affecting erase/write speed - MT25QU01G
by Mathijs Van de Poel 17 Mar '25

17 Mar '25

Hello, We are using the driver to write to a MT25QU01G memory over SPI. I tried various speeds using the spispeed parameter but the erase/write times stayed the same. Any idea how I could improve this speed? time sudo flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=100000 -c "MT25QU01G" -E time sudo flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=100000 -w MT_file.bin -V -c MT25QU01G Spispeed Delete [min] Write [min] 16000 14 17 20000 13.5 15.43 25000 13.41 18.5 100000 14.4 17 Thank you in advance, Mathijs -- This email is private and confidential.

old wiki website goes away in a month
by Anastasia Klimchuk 07 Mar '25

07 Mar '25

Hello people, This is the news: old wiki website wiki.flashrom.org goes away in one month. It still stays around for one month, in case someone needs to do something - migrate a doc to the new website, or download a doc, etc. Official website is flashrom.org It has been almost two years that wiki has that red deprecation banner on the top and was locked for editing. Now the time has come for the next step. For stats, during these two years we had: 47 documentation pages migrated to the new website, and their urls are already redirected to new website, and 63 pages were decided to be outdated and they will go away, If you disagree with the decision made on any of these 63 pages, it would be super helpful if you help to migrate that doc (wiki is still available for a month). You will need to commit to be the reviewer of the doc content. You can create the patch yourself (see https://flashrom.org/how_to_add_docs.html) or ask me, or post here on the list. But in any case, you will need to review the content. After one month, wiki will be gone, however it will stay on the web.archive.org (in fact, it's already there). So if you suddenly remember about some good old doc later, it can be pulled from the web archive and migrated (but see above). Important thing to say: these 47 pages did not migrate themselves. And while I did create most of the patches, each patch needs to be reviewed by someone who is not the owner of the patch. I want to say thank you so much to all the reviewers who put their effort in this, and reviewed old docs! <3 Also special thank you to Patrick Georgi and Stefan Reinauer who are our amazing infra admins and supported this two years long effort! <3 -- Anastasia.

Flashing Eon EN25Q32(A/B) with CH341A – Findings & Inquiry
by Jonathan Kendall 06 Mar '25

06 Mar '25

Dear Flashrom Team, I wanted to share my experience and findings while working with flashrom to flash an Eon EN25Q32(A/B) SPI flash chip using a CH341A programmer with a SOIC clip. My goal was to flash SeaBIOS onto the chip as part of an experiment for a Lenovo ThinkPad T430u. Summary of My Process: 1. Successfully dumped and verified the original firmware using `flashrom -r`. 2. Encountered inconsistencies in chip detection, where it was sometimes identified as EN25Q64 (8MB) instead of EN25Q32 (4MB). 3. Managed to successfully erase and flash the chip by forcing the write process despite WP (Write Protection) warnings. 4. Verified the flashed BIOS integrity through multiple MD5 checksum comparisons. 5. Confirmed that the flashing was successful but experienced occasional inconsistencies with readback verification. Key Observations & Questions: - The CH341A programme sometimes fails to detect the chip or identifies it incorrectly. Could this be due to power delivery issues or specific quirks of the CH341A? - Write Protection messages were displayed, but forcing the flash succeeded. Does flashrom support unlocking this chip, or is WP handling dependent on external hardware? - Are there any recommended workarounds to improve stability and ensure more consistent reads/writes on this chip? - I would be happy to contribute testing logs if that would be useful for adding better support for this flash chip in future versions of flashrom. Thank you for your work on flashrom! Please let me know if any additional details would be helpful. Best regards, Jonathan Kendall

Flashrom Write Verification Failure on Conga-TC570 (Intel Tiger Lake)
by ליאור סלמונה 06 Mar '25

06 Mar '25

*Dear Flashrom Developers,* I am experiencing an issue with *flashrom v1.1* on *Linux 5.15.86 (x86_64)* while attempting to flash a *Macronix MX25L25635E* SPI NOR flash chip on my *Conga-TC570* board, which features an *Intel® Core™ i5-1145GRE (Tiger Lake)* processor. *Issue Details:* - When the flash is *clean* (filled with 0xFF), I can *erase* and *write* successfully. - However, *verification fails*, reporting mismatched data. - The failure occurs *at address 0x00000000*, with the following error: FAILED at 0x00000000! Expected=0x11, found=0x00 Failed byte count from 0x000000 - 0x01FFFFF: 0x8DD2A6 *Steps Taken So Far:* 1. *Checked Write Protection* using flashrom -p internal --wp-status → No active protection. 2. *Attempted manual erase* before writing: flash_erase /dev/mtd0 0 0 flashrom -p internal -w bios.bin 3. *Loaded Intel SPI modules*: modprobe intel_spi_pci modprobe intel_spi_platform 4. *Verified SPI device detection*: ls /sys/bus/spi/devices/ The SPI device appears correctly. 5. *Tested alternative flashing methods*: - Using dd: dd if=bios.bin of=/dev/mtd0 bs=4096 Result: *Write completes, but verification still fails.* - Using flashrom -p internal -V for verbose output (logs available on request). *Questions:* 1. Is this a known issue with flashrom on *Tiger Lake* platforms? 2. Could the *Intel SPI controller* be interfering with writes? 3. Are there any debugging steps or patches I should try? Any guidance would be greatly appreciated. Thank you for your support! Best regards, *Lior Salmona*

This flash part has status UNTESTED for operations: WP
by Martin Gabriel Fleck 06 Mar '25

06 Mar '25

Hi, after using flashrom to flash coreboot to a Yanling device from Aliexpress, I came accross your message: ``` This flash part has status UNTESTED for operations: WP The test status of this chip may have been updated in the latest development version of flashrom. If you are running the latest development version, please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash chip. Please include the flashrom log file for all operations you tested (see the man page for details), and mention which mainboard or programmer you tested in the subject line. You can also try to follow the instructions here: https://www.flashrom.org/contrib_howtos/how_to_mark_chip_tested.html Thanks for your help! ``` I was following the instructions of https://www.flashrom.org/contrib_howtos/how_to_mark_chip_tested.html You write "To see the examples of such patches, have a look at commit history of flashchips.c." Two confusions on my side, regarding this: #1 Looking at such commits, I see that flashchips.c is eddited in a line number much higher than the total line number of this file in my copy of the repo. (The version in my repo (latest main) contains 305 lines.) I'm confused by this. #2 My case seems to me: That I'm not marking an existing chip as tested. It seems to me I should be adding a completely new chip. Is there documentation for this as well? It seems to me my confusion #2 is because of confusion #1. In any case, I'd be happy to add the provided info in a patch / commit to your repo. I attached the logs of the operations I did (one log file per command). I hope you can clear up #1 above. Let me know how to continue from here. Kind regards, Martin Gabriel Fleck / Martin

flashrom's Hall of Fame
by Anastasia Klimchuk 02 Mar '25

02 Mar '25

Good day, We have created flashrom's Hall of Fame! We want to give credits to all the people who made contributions to flashrom over the years, and decades. The page pulls the info from the git history (which starts from January 2002!), and it is presented in two sections: Authors and Reviewers. Information is updated regularly (and by the script, no human needed). Everyone is very welcome to have a look and read! https://flashrom.org/about_flashrom/hall_of_fame.html I got this idea of pulling info from git history, and checked that git history goes back to Jan 2002 (perfect). But the idea might still be only in my head, if not Peter Marheine who actually implemented everything and made it work. Thank you! The main challenge was to make it work automatically, without humans needing to update the page. If anyone curious, here is the patch how it works: https://review.coreboot.org/c/flashrom/+/86350 We have these words at the entrance of the Hall, but I want to put it here in this post, too: flashrom is alive and running because of you all, the people who during all these years (and decades!) give their time, energy, knowledge, and a piece of their heart to flashrom. The project is what we all are creating together. *Thank you everyone so much!* -- Anastasia.
