Flashrom/0.9.5

Release announcement

After over ten years of development and constant improvement, the flashrom developers are happy to announce the release of flashrom 0.9.5.

flashrom is a utility for reading, writing, erasing and verifying flash ROM chips.

flashrom is designed to flash BIOS/EFI/coreboot/firmware/optionROM images on mainboards, network/graphics/storage controller cards, and various programmer devices. It can do so without any special boot procedures and from your normal working environment.

Highlights of flashrom

• Parallel, LPC, FWH and SPI flash interfaces.
• Support for onboard programming and external programmers.
• 288 (+4 since 0.9.4) flash chip types with a number of variants each.
• 177 (+4 since 0.9.4) different chipsets, some with multiple flash controllers.
• 374 (+68 since 0.9.4) mainboards verified to be working.
• Flash chip package agnostic. DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32/40/48, BGA and more have all been verified to work.
• FIXME PCI devices, FIXME USB devices, FIXME parallel port device, and all external serprog-based programmers can be flashed or used for flashing.
• No physical access needed. root access is sufficient.
• No bootable floppy disk, bootable CD-ROM or other media needed.
• No keyboard or monitor needed. Simply reflash remotely via SSH.
• No instant reboot needed. Reflash your ROM in a running system, verify it, be happy. The new firmware will be present next time you boot.
• Crossflashing and hotflashing is possible as long as the flash chips are electrically and logically compatible (same protocol). Great for recovery.
• Scriptability. Reflash a whole pool of identical machines at the same time from the command line. It is recommended to check flashrom output and error codes.
• Speed. flashrom is much faster than vendor flash tools.
• Supports Linux, FreeBSD, NetBSD, DragonFly BSD, OpenBSD, Nexenta, Solaris, Mac OS X and DOS. Please refer to the README for build instructions.

Thanks go to everyone who contributed to flashrom over the years.

Please note that rewriting your flash chip can be dangerous and flashrom developers make no guarantees whatsoever. That said, many users have successfully replaced proprietary tools such as awdflash, amiflash and afudos with flashrom.

New major user-visible features

• Support for new programmers:
  • FTDI FT2232-based:
    • Dangerous Prototypes Bus Blaster
    • TIAO/DIYGADGET USB Multi-Protocol Adapter (TUMPA)
    • GOEPEL PicoTAP
  • Rayer-compatible:
    • Xilinx parallel III (DLC5)
  • Linux SPI subsystem (spidev)
  • AMD Hudson chipsets
  • Intel Tunnelcreek chipset
  • RDC R6030 chipset (found on the bifferboard)
• Intel Hardware Sequencing

  Intel chipsets can be accessed via Hardware Sequencing now. This is a major step for better support of current, locked-down Intel-based mainboards (but it is not enough yet).

• Intel locks

  Newer Intel chipsets provide various methods to lock (parts of) the flash address space. flashrom tries to inform the user better if such locks are detected.

• SPI support for serprog
• Speed up on dediprog
• The supported voltage ranges are now printed for each flash chip when called with -L, --list-supported (and -V).
• There are 3 levels of verbosity now, hence -VVV shows the most detailed messages.
• Better build support for PPCs.
• Initial build support for the ARM architecture (little-endian only)
• Replace --mainboard with -p internal:mainboard

Infrastructural improvements and fixes

• struct flashctx
• programmer-centric probing
• SPI command black-/ignorelisting for the SPI flash chip emulator
• Code cleanups
