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.

Erase fails with flashrom using mtd
by Sakthipriya M July 29, 2025

July 29, 2025

Hi, We are using customised Elkhart lake board, when we tried to update BIOS using flashrom, following error is reported, "linux_mtd_erase: MEMERASE ioctl call returned -1, error: Input/output error". But sometimes we could update BIOS successfully. Chip size is 16MB, Flashrom erases successfully till 6MB and fails then Flashchip: Macronix MX25L12835F OS: GNU/LINUX Kernel: Tried in 6.12.5 and 6.14.2. Ensured that MTD kernel configurations are enabled. Flash chip is detected as "BIOS" in /dev/mtd0. Thanks, Sakthipriya M

Hello, I tried to read an FM25F01(https://eng.fmsh.com/nvm/FM25F01_ds_eng.pdf) which is failing and you asked to sent an email, same setup with an W25X20CL is working. sudo flashrom -p linux_spi:dev=/dev/spidev0.1 -r firmware_dump.bin flashrom unknown on Linux 6.12.25+rpt-rpi-v8 (aarch64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Using default 2000kHz clock. Use 'spispeed' parameter to override. Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on linux_spi. === This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE 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. Thanks for your help! Read is not working on this chip. Aborting. Mit freundlichen Grüßen/Best Regards Daniel Kuhl

Hello, I suppose there is no one speaking french here so I'll try it in english : I have a *Dell Optiplex 3060 Micro* with a *RTL8111/8168/8211/8411* PCI Express Gigabit Ethernet Controller : root@X103375:~# lspci -nn |grep Ether 01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15) I really need an ipxe entry to point to an HTTP server, but I cannot use DHCP, so I would be glad to flash this controller to use ipxe (without USB key or DHCP). Does someone know if it's possible ? Thanks in advance. Ewan
