v2025.0.0

Fixed

• greatfet_msp430 causes the GreatFET firmware to enter an infinite loop if the JTAG interface cannot be initialized.

Changed

• greatfet_usb-capture will now exit with a warning if it cannot find a GreatFET Rhododendron Neighbour.
• Updated libgreat to v2024.0.5.

Added

• Updated the greatfet_msp430 documentation to provide more detail on JTAG pin connections.
• Updated the Getting Started documentation to recommend the use of greatfet host-tools --ensure-access instead of manual udev rule installation.

Security

• Update jinja2 from 3.1.4 to 3.1.6.

Removed

• Deleted the udev rules file in host/util/. Copies of the rules for uaccess and plugdev can still be found in host/greatfet/assets/.

v2024.0.4

Fixed

• Serial packets were framed incorrectly when using the GreatFET UART interface with parity set to one of: ODD, EVEN
  or PARITY_STUCK_AT_ONE

Changed

• Updated libgreat to v2024.0.3

v2024.0.3

Fixed

• Permission denied error when using logic analyzer on Windows.

v2024.0.2

Fixed

• The GreatFET shell was unable to access globals inside user defined functions.
• Import errors on some Python distributions.

Changed

• Updated pyfwup dependency to 0.5.2
• Updated libgreat dependency to
  v2024.0.2

Added

• Windows support for Cynthion.

release v2024.0.1

This the fourth major release of the GreatFET software and firmware stacks. As usual, this release contains firmware images in firmware-bin, host software in host-packages, and a copy of all sources necessary to build the entire codebase.

Upgrading to this release

You can upgrade the GreatFET host tools to the latest release with:

pip install --upgrade greatfet

After upgrading the host tools, update your GreatFET firmware to the latest release with:

greatfet_firmware --autoflash

Happy hacking!

Changelog

v2024.0.1

GreatFET

Changelog

v2024.0.0

GreatFET

• gpio: add support for configuring all gpio pin modes
• uart: fix python KeyError when parity argument not specified
• shell: support versions of IPython >= 3.11
• facedancer: fix usb mass storage example
• shell: fix runtime errors when using uart functionality

libgreat

• Added TX & RX pin definitions for UART1, USART2&3
• Implement NXP's recommended PLL setup sequence
• Add support for configuring all gpio pin modes
• Don't try to claim USB interface on Windows
• Add initial implementation of usb1 bulk transfer backend
• Do not set USB device address to zero

release 2021.2.1

The third major release of the modern GreatFET software and firmware stacks. As usual, this release contains firmware images in firmware-bin, host software in host-packages, and a copy of all sources necessary to build the entire codebase.

NOTE: We no longer support Python 2. This release targets Python 3.6+.

Highlights for this release:

• This release adds a new chipcon programmer for Texas Instruments CCxxxx ("SWRA124") devices.
  • In Python: chipcon = gf.create_programmer('chipcon')
    • From there you can perform manual operations like chipcon.run_instruction() and read_xdata_memory(),
    • Or use higher-level interface methods like program_flash() and read_flash().
  • Flash operations can also be done from the command line with greatfet chipcon.
• This release adds a new programmer for Microchip I2C EEPROM devices: eeprom = gf.create_programmer('microchipEEPROM', device='24LC128').
  • This mainly provides two higher-level methods: read_bytes(start, end), and write_bytes(start, data).

Major bugfixes:

• #344: Facedancer with bMaxPacketSize0 < 32 does not work.

Happy hacking!

release 2020.1.2

This is a hotfix release! The I2C API for scanning was broken on the host side
from a simple typo. This has been fixed.

release 2020.1.1

This is the second major release of the modern GreatFET software and
firmware stacks. It includes firmware images (in firmware-bin) and
host software (in host-packages), as well as a copy of all sources
necessary to build the entire codebase.

NOTE: This is the last release that will support Python 2, as it has been retired.
Further releases will target Python 3.6+.

Some highlights of the changes include:

• in the Python API, 'peripherals' have been renamed to 'interfaces'
  • programmers have been brought out into greatfet.programmers
    • programmers are created by name: spi = gf.create_programmer('spi')
• a JTAG interface, with a command-line helper greatfet jtag
• greatfet shell now has IPython Magic, such as %reload
  • The preamble text when running greatfet shell has more information
• the DAC API and command-line helper (greatfet dac) have been rewritten
  • greatfet dac -f voltage 2.2
• bus-pirate emulation! greatfet pirate
• greatfet info now has --host to print information about the host environment
• GNU Radio 3.8 support, with ADC blocks, and other cleanups

Major bugfixes:
- #283: USB packets that are 64 byte aligned in data size are not forwarded through the usbproxy on the GreatFET One

Happy hacking!

release 2019.9.1

This is the first major release of the modern GreatFET software and firmware stacks. It includes firmware images (in firmware-bin) and host software (in host-packages), as well as a copy of all sources necessary to build the entire codebase.

NOTE: The recommended way to update your GreatFET for this release is to install the host tools (either from the host-tools folder or from pip), and then to use "greatfet firmware --autoflash". This will ensure that your firmware and host tools match, which is the best way to make sure everyone gets along.

This version adds a significant number of features -- it'd be prohibitive to list them all here! Checkout the RELEASENOTES file in the archive for more information.
