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

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

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.
