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
