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!

v2021.2.1

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.
