Verification after write vs erase operations
by Anastasia Klimchuk Aug. 10, 2025

Aug. 10, 2025

Hello everyone, I want to bring into discussion a topic of verification of chip content which is performed after write or erase operations. Also for context prior discussion in this ticket: https://ticket.coreboot.org/issues/520 Currently we have a flag `-n` or `dont_verify_it` which is false by default. What the flag is doing is deciding whether verification needs to be performed after writing. The flag is false by default, so by default verification is happening after writing (which makes sense). Now the flag is only controlling write operation, and has no effect on erase operation. So for erase, the flag is ignored and verification is performed always. Just for context, it has always been like this. So for write operation we have a power option to say "ignore verification", and since it's false by default, the idea is, if you set it true then you know what you are doing. There is no such option for erase which seems a bit unfair. The two potential options to introduce equivalent option for erase are: 1) Add new flag `dont_verify_erase` (or some similar name) As a support for this option, it does not affect any existing use cases/scripts, and can be added any time. 2) Add coverage for erase operation under existing flag `-n` or `dont_verify_it` As a support for this option, erase operation can be seen as a variant of writing, since it does modify content of the chip, and so the fact it's not covered by the existing flag can be treated as a bug. What do people think about it? -- Anastasia.

Splitting flashchips.c
by Anastasia Klimchuk Dec. 6, 2024

Dec. 6, 2024

Good day, I wanted to confirm that we are splitting flashchips.c file into separate files per vendor. flashchips.c will still stay in the source code but it will be much smaller and will only contain "generic" chip entries. The patch is here: https://review.coreboot.org/c/flashrom/+/83307 , it will be submitted after v1.5.0 tag is done. The patch will not be included in v1.5.0 release. There will be no changes to the usage, and everything that's supported stays the same. If you are a flashrom user who does not look into source code: this does not affect you at all. If you are working on adding support for a chip model: when the patch is submitted (I will post again) you will need to copy your code from flashchips.c into a vendor-specific file. Thank you! -- Anastasia.

release v1.5.0 plan and timeline
by Anastasia Klimchuk Nov. 28, 2024

Nov. 28, 2024

Good day everyone, We are doing one more release this year! It's a smaller scope than the previous one, but will contain some important things. We now have a document describing release process in details: https://flashrom.org/dev_guide/release_process.html so I will just tell the dates: 15 November: tagging v1.5.0-rc1 6 December: tagging the release v1.5.0 Between 15 November and 6 December we are focused on testing and bugfixing, so no new features will be submitted during that time. The patches can still be pushed and reviewed, but submit will need to wait for after we tag v1.5.0 (ETA 6 December). Bugfixes will be submitted as usual. Any help with buildind/testing/bugfixing is very much appreciated! https://flashrom.org/how_to_support_flashrom.html#building-and-testing-1 What's included in the next release? We now have a document which accumulates info about recent development (for any next release): https://flashrom.org/release_notes/devel.html It's not full final release notes, some things might be missing: for example I will soon add the "Bugs fixed" section there. Lastly, we plan to split flashchips.c into separate smaller files per vendor. The file grew huge, and it's time to split. To minimise the disruption for contributors who are adding support for new chip models, we plan to do this between 15 November and 6 December, when there are less contributions. This work will be submitted only after v1.5.0 tag. -- Anastasia.

Hello, I can not disable write protect with flashrom on these devices. It keeps saying, "unknown WP error" or "Your flash chip is in an unknown state". Any information would be helpful. Thank you, John

Subject: Issue with flashrom on AMD FP4 chipset and unrecognized SMBus revision
by DAVID GOMEZ CRUZ Nov. 12, 2024

Nov. 12, 2024

Dear flashrom team, I am encountering an issue when trying to use flashrom on a system with an AMD FP4 chipset. Upon attempting to access the flash memory, I receive the following error messages: flashrom v1.2 on Linux 6.4.0-150600.23.25-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 chipset "AMD FP4". Enabling flash write... Disabling read write protection of flash addresses from 0xfffff800 to 0x0007f7ff failed. Disabling read write protection of flash addresses from 0xfffff800 to 0x0007f7ff failed. Disabling read write protection of flash addresses from 0xfffff800 to 0x0007f7ff failed. Disabling read write protection of flash addresses from 0xfffff800 to 0x0007f7ff failed. FCH device found but SMBus revision 0x71 does not match known values. Please report this to flashrom(a)flashrom.org and include this log and the output of lspci -nnvx, thanks!. Could not determine chipset generation. PROBLEMS, continuing anyway No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically. I have attached the lspci_output.txt file with the full output from the lspci -nnvx command, as suggested by the error message. I am seeking a solution to access the flash memory for reading or writing, but it appears that my chipset and SMBus revision may not be fully supported or recognized by flashrom. I would greatly appreciate any guidance or solutions you can provide. Thank you for your attention and for the excellent work on flashrom. I look forward to your response. Best regards, David

RPMC feature addition for v1.5
by Matti Finder Nov. 11, 2024

Nov. 11, 2024

Hello, Over the last few weeks I have been adding support for the Replay protected monotonic counter commands to flashrom. Their functionality is defined in the JESD260 specification [1]. Currently they only work by manually setting the flash chip to use SFDP-capable chip. This is done with `-c "SFDP-capable chip"`. This enables automatic feature detection by parsing the corresponding SFDP-table. If you want to enable this new feature on supporting flashchips, this is done by setting the FEATURE_FLASH_HARDENING bit and then setting the correct values within the rpmc_ctx struct. Usage of the commands is explained here [2]. They just made the cutoff and so this new feature will be a part of flashrom v1.5. Best Regards, Matti.

Re: Support for GD25LR512ME flash chip.
by Anastasia Klimchuk Nov. 1, 2024

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!
