Erase fails with flashrom using mtd
by Sakthipriya M 28 Apr '25

28 Apr '25

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

W25Q256JV_Q is checked

hi, I checked the PROBE - READ - ERASE - WRITE operations of the W25Q256JV_Q flash with J-Link and CH341 spi writers. the flashrom version was the newest development release at 2025-04-14 (#4d4688ccf132c580107b013d2d929a0816aa89c1) I made a little modification in the 'jlink_spi.c' source, because I use the power supply from the J-Link device pin 19. this power is 5V, I put a 3.3V LDO (HT7333) after it, and this LDO (and decoupling capacitors) need more time to fix output voltage. I attached the patch file. [ I tried to ask merge request via Jenkins, but it was too complicated for modify one char in the source ;-) ] my flash type was Winbond 25Q256JVEQ, which recognized by flashrom to W25Q256JV_Q or W25Q256FV, both type probed, read, wrote, erased, both modality worked fine. regards, Attila

Reg: MEMERASE ioctl call returned -1, error: Input/output error

Hi All, We are trying to update the BIOS using the flashrom utility on the Elkhart Lake (LEC-EL) x86 platform, but we are facing the issue: "linux_mtd_erase: MEMERASE ioctl call returned -1, error: Input/output error" when running the flashrom tool. Please see below the attached error log for your reference. System Configuration: * Ubuntu 24.04 * Kernel Version: 6.13.7 NOTE: We have previously used this tool to upgrade and downgrade the BIOS without issues, but we are currently encountering this error. ERROR MESSAGE: $ sudo flashrom -p linux_mtd:dev=0 -w /home/adlink/Documents/LEC-EL_10710_FullImage/LEC-EL_10710.BIN -V flashrom v1.5.1 on Linux 6.13.7 (x86_64) flashrom is free software, get the source code at https://flashrom.org flashrom was built with GCC 13.3.0, little endian Command line (5 args): flashrom -p linux_mtd:dev=0 -w /home/adlink/Documents/LEC-EL_10710_FullImage/LEC-EL_10710.BIN -V Initializing linux_mtd programmer get_mtd_info: device_name: "BIOS", is_writeable: 1, numeraseregions: 0, total_size: 16777216, erasesize: 4096 Opened /dev/mtd0 successfully The following protocols are supported: Programmer-specific.

Erase/write failed. Checking if anything has changed. Reading current flash chip contents... read_flash: region (00000000..0xffffff) is readable, reading range (00000000..0xffffff). done. Good, writing to the flash chip apparently didn't do anything. Please check the connections (especially those to write protection pins) between the programmer and the flash chip. If you think the error is caused by flashrom please report this to the mailing list at flashrom(a)flashrom.org or on IRC (see https://www.flashrom.org/Contact for details), thanks! Could you please suggest if any kernel configuration needs to be changed? We would appreciate your input. Thanks & Regards, Arvind G P.
