Recent development (unreleased)

This document describes the major changes that are expected to be included in the next release of flashrom and which are currently only available by source code checkout (see Building from source). These changes may be further revised before the next release.

Known issues

AMD-based PCs with FCH are unable to read flash contents for internal (BIOS flash) chips larger than 16 MB, and attempting to do so may crash the system. Systems with AMD “Promontory” IO extenders (mostly “Zen” desktop platforms) are not currently supported.

Added support

  • Intel Wildcat Lake chipset

  • Eon EN25QX128A

  • PUYA P25D80H

New features

Fail immediately when trying to write/erase wp regions

This change is done so it’s harder for user to brick his own platform. Information about read-only regions can easily be missed as flashrom can output a lot of information on screen. Even if you notice you might not know if one of the regions you requested falls inside read-only range, especially if using different names for those regions. If you are flashing multiple regions or ones that partially overlap with read-only parts then that could result in flashrom failing in the middle, leaving you in unknown state.
