BIOS update fails on a Minix Z100-0db device
by Robert 04 Jan '25

04 Jan '25

Hi guys, I tried to update the BIOS on my Minix Z100-0db device so that I can boot a Linux UEFI from the NVME disk. Pls. see below: 1. As per https://theminixforum.com/index.php?threads/guide-updating-bios-uefi-using-… I downloaded the newest image for Minix:AD0J0181.bin (well download zip, decompress) 2. I booted the device from an archlinux install USB and copied the new image there so I can access it 3. I installed flashrom to the arch install OS (pacman -S flashrom), the version is 1.5.1-1, compiled Dec 20 2024 4. I made a backup of the current version: flashrom -p internal -c "Opaque flash chip" -r my_backup_bios_AD0J0161.bin ... so far so good .. 5. I attempted to upload the new binary: flashrom -p internal -c "Opaque flash chip" -w my_backup_bios_AD0J0161.bin issue follows: Opened /dev/mtd0 successfully Found programmer flash chip "Opaque flash chip" linux_mtd_wp_read_cfg: ioctl Operation not supported Failed to unlock flash status reg with wp support. Reading old flash chip contents... done. Updating flash chip contents... linux_mtd_erase: MEMERASE ioctl call returned -, error: Input/output error Erase/write done from 0 to ffffff Write Failed!Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... done. Apparently at least some data has changed. Your flash chip is in an unknown state. Get help ... Retried with -f, which in turn again changed something, but same outcome. I did not try to put back the original image so far, it would probably give me the same The device is still on sitting in the arch install shell, I increased the install disk size and added a few packages to help with the possible fix, since I believe if I would try to reboot, the device would be lost, and I would likely have to replace it. I am a long time linux user, can try any workaround or optionally even allow ssh access to the device. Can someone please give me some hints about where to go from here. Appeciate your time, Robert

flashrom point release v1.5.1 is out
by Anastasia Klimchuk 22 Dec '24

22 Dec '24

Good day everyone, We have one more release this year (this is the last one of this year, for sure :)). It contains one bug fix for the bug which was introduced in v1.5.0. Bug fix is also merged into the main branch, so building from the latest source works too. Details: Users with older Intel-based platforms (Broadwell/Braswell and earlier) flashing using the internal programmer option might encounter an ‘Invalid OPCODE’ error when erasing/writing which would lead to an incomplete flash and potentially a bricked device. External flashing was not affected at all. Ticket: https://ticket.coreboot.org/issues/573 Patch: https://review.coreboot.org/c/flashrom/+/85612 Release notes: https://flashrom.org/release_notes/v_1_5.html#version-v1-5-1 Git tag: v1.5.1 (in branch 1.5.x) Tarball: https://download.flashrom.org/releases/flashrom-v1.5.1.tar.xz Signature: https://download.flashrom.org/releases/flashrom-v1.5.1.tar.xz.asc Fingerprint: 6E6E F9A0 BA47 8006 E277 6E4C C037 BB41 3134 D111 Thanks heaps to people who helped to do v1.5.1 to get it ready before holidays break! <3 I wish everyone a nice and happy holidays time. -- Anastasia.

Reg:libmtd: error!: MEMERASE64 ioctl failed for eraseblocks (mtd0)
by Arvind GP 15 Dec '24

15 Dec '24

Hi All, We are trying to implement the flashrom tool utility on the x86 Elkhart Lake(LEC-EL) platform. In this case, we are facing an issue when trying to erase the BIOS device MTD0. There are 4096 erase blocks available in the mtd0 device, but only 1791 erase blocks we can erase; the remaining blocks are throwing errors, and it shows MEMERASE64 IOCTL FAILED. Please see the below error message and MTD0 device info for your reference. NOTE: Sometimes it works; we can erase the MTD0 device without any error, and we can upgrade/downgrade the BIOS. ERROR MESSAGAE: #sudo flash_erase /dev/mtd0 0 0 Erasing 16384 Kibyte @ 0 -- 0 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 0 (mtd0) error 524 (Unknown error 524) flash_erase: error!: Entering into mtd_erase_multi flash_erase: error!: /dev/mtd0: MTD Erase entire chip failureTrying one by one each sector. error 524 (Unknown error 524) Erasing 4 Kibyte @ 700000 -- 43 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 1792 (mtd0) error 5 (Input/output error) flash_erase: error!: /dev/mtd0: MTD Erase failure error 5 (Input/output error) Erasing 4 Kibyte @ 700000 -- 43 % complete cnt 4096 MTD0 INFO:(sudo mtdinfo /dev/mtd0) Name: BIOS Туре: nor Eraseblock size: 4096 bytes, 4.0 KiB Amount of eraseblocks: 4096 (16777216 bytes, 16.0 MB) Minimum input/output unit size: 1 byte Sub-page size: 1 byte Character device major/minor: 90:0 Bad blocks are allowed: false Device is writable: true Please share your inputs on this.

Splitting flashchips.c
by Anastasia Klimchuk 05 Dec '24

05 Dec '24

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.
