v1.3 (Feb 2023) — flashrom 1.4.0 (git:v1.4.0) documentation

# v1.3 (Feb 2023)

It has been almost three years since our last release. All this time we have been working on enhancing the flashrom code base. This new release comes with a lot of new features, programmers, improvements, and bug fixes. A detailed but not exhaustive change log is presented below.

## New major user-visible features

- Support for the Linux I2C subsystem

- Option to read/write only region to/from ROM is renamed to `--include` (`--image` option is deprecated and exist only for back compatibility). An optional sub-parameter (`--include <region>[:<file>]`) to allow building the image to be written from multiple files is added

- Support different SPI modes (Dual IO, Quad IO, Normal, Fast Read) for AMD’s chipsets (>= Bolton)

- Support for Write Protection configuration (`--wp-disable`, `--wp-enable`, `--wp-list`, `--wp-status`, `--wp-range`, `--wp-region`)

- Add SPI SR2/SR3 read/write support

- The Intel chipset detection has been improved

- Bus Pirate SPI

  - New parameter to control the external Vcc state (`psus=<on|off>`)

- Dediprog

  - Add 4BA support on SF600 protocol version 3

- Dummyflasher

  - New parameter to allows emulating a bus/chip frequency (`freq`)

  - New parameter to emulate flash erase with either 0x00 or 0xff (`erase_to_zero`)

  - Add emulation for S25FL128L chip

  - SR2, SR3 and WP is emulated for W25Q128FV

  - Emulate variable-size SPI flash chip (4-byte address format is supported)

- FT2232 SPI dongles

  - New parameter to search FTDI by description, i.e. product string (`description`)

- SEGGER J-Link and compatible devices

  - New parameter to active the 5V power supply during a flash operation (`power`)

- Drop “Promontory” architecture (AMD) support

- End Of Life (EOL) for ITE IT85* specific code

- README and man page updated with additional information

The greatest increase in the speed of operations can be seen on the following programmers: SPI on Intel NICs, FT2232 SPI dongles

## Libflashrom

- Add Write Protect functions to the API

- Add rust Foreign Function Interface bindings for the libflashrom API

- Move documentation from source file to header

- Drop `flashrom_system_info()`

- Drop `flashrom_supported_programmers()`

- Add `flashrom_layout_get_region_range()`

- Declaration change from `flashrom_layout_read_fmap_from_rom(struct flashrom_layout **const, struct flashctx *const, off_t, size_t)` to `flashrom_layout_read_fmap_from_rom(struct flashrom_layout **const, struct flashctx *const, size_t, size_t)`

- Allow NULL-pointer argument in `flashrom_flash_release()`

## Infrastructure expansion

- Add blackbox test uber-script

- Add E2E tester for a specific chip/chipset combo

- Build script for Jenkins was upgraded and move to repository - `test_build.sh`

- Add a set of Dockerfiles for build testing - `util/manibuilder`

- Add a Nix shell file which is able to compile flashrom - `util/shell.nix`

- Add CMocka unit-test infrastructure into the meson build system (test for drivers available only if its driver is built). The following tests are included:

  - Core logic tests

  - Basic lifecycle for `dediprog`, `nicrealtek`, `raiden_debug_spi`, `parade_lspcon`, `mediatek_i2c_spi`, `realtek_mst_i2c_spi`

  - Basic lifecycle + chip probe for `dummyflasher`, `linux_mtd`, `linux_spi`

  - Layout tests (overlapping, sanity checks, invalid range/address)

  - Erasing/reading/writing/verifying chip tests

  - Write Protect tests

  - And others!

- Introduce `MAINTAINERS` file

- Rename `z60_flashrom.rules` to `flashrom_udev.rules`

- Introduce linter for git sign-off-by line

- Move all header files to the new `include` directory.

### Meson

The minimum version has been increased. Requires at least `0.53.0`.

- Added build instructions - `Documentation/building.md`

- Allow libflashrom to be built as a static or shared library.

- Add new options: `print_wiki`, `ich_descriptors_tool`, `classic_cli`

- Rename `print_wiki` to `classic_cli_print_wiki` option

- Install the man file

- Fix compilation under uClibc-ng

- Add missing config option for J-Link SPI

- Treat warnings as errors and use the same warning options as in Makefile.

### Makefile

- Add support for Elbrus (e2k) architecture

- Make pkg-config mandatory to find `libftdi1`, `libjaylink`, `libusb1`, `libpci` (you still can override detection and set cflags and ldflags manually)

- Merge `compiler`, `hwlibs`, `features` targets into `config` target

- Drop `distclean` target

- Drop STANDALONE mode

- Summarize systems with the same CPPFLAGS and LDFLAGS

- Only enable I2C programmers on Linux (linux-specific code)

- Revise C compiler check, utsname and clock_gettime test, detection of Linux specific headers

- Since the NI-845x is a Windows only proprietary library, disable it by default.

- Enable the internal programmer on x86 or linux.

- Fix building on AArch64 NixOS

Various broken and missing dependencies have been fixed for these two build systems.

## New programmers

- Chrome EC based debug tools - SuzyQable, Servo V4, C2D2 & uServo

- Realtek RTD2142 MST

- Parade lspcon USB-C to HDMI protocol translator

- DirtyJTAG (a USB-JTAG firmware for STM32 MCUs)

- MediaTek LCD controller

- Programmers based on FT4233H FTDI

- Kristech KT-LINK

- Variants of STLINK-V3: STLINK-V3E, STLINK-V3S, STLINK-V3 With dual VCP, STLINK-V3 Without MSD

At some point, flashrom supported ENE LPC interface keyboard controller and Microchip MEC1308 embedded controller. But they were dropped before the release because the code was no longer maintained by anyone. If you’re interested, take a look at git history.
