v0.16

Release Notes:

• F7 Firmware: Enable over-drive voltage mode
  • Required for reliable 216MHz operation (see datasheet)
• Bootloader update:
  • gw.py update --bootloader updates the bootloader
  • Not normally required
  • Failure may brick the Weazle and require full reflash: Take care!
• Update build system to work with Windows MinGW environment

v0.15

Release Notes:

• Host tool improvements:
  • IPF: More robust conversion to raw flux for writeout
  • HFE: Fix crash when writing out HFE from third party tools
  • F7 Firmware improvements:
    • Preparation for High Speed USB (future board using 730Z8 MCU)
    • Enable Instruction and Data caches (10x execution speedup)
    • Various improvements to bandwidth as reported by gw.py bandwidth

v0.14

Release Notes:

• IPF: Full write support (weak data, index misalignment)
• New GW commands: bandwidth, erase
  • bandwidth: Measure USB read/write bandwidth
  • erase: Erase a disk
• F7 USB: Improved bandwidth when writing to disk
  • Much less likely to see FluxUnderflow failures
• update: Fix a bug which could fail to reopen the GW device for update
• update: Automatically find the update file if filename not specified
• Control script: Tidier notification of errors (no scary backtrace)

v0.13

Release Notes:

• HFE: Read & write support
• IPF: Preliminary write support
  • Requires SPS/CAPS support library. See the wiki.
  • Weak data not yet supported (RNC "Protect Process" protection, & others)
  • Write splice is always rotated to the index (affects Speedlock & others)
  • Also TODO: Verified writes
• USB: Use the VID:PID pair assigned to Greaseweazle (1201:4d69)
• IMPORTANT NOTES:
  • New prerequisite: bitarray module. See the wiki.
  • The write parameter --adjust-speed is removed.

v0.12

Release Notes:

• GW Autodetect: General improvements, and now works on Windows 7
• New read parameter --double-step to double-step drive heads
  • Useful for reading a 40-cylinder disk in an 80-cylinder drive
• New 'pin' command allows a floppy pin to be set to specified level
  • Currently supported only for pin 2 (DENSEL)
• New 'reset' command resets the Greaseweazle to power-on settings
  • Motors off, drives deselected, power-on pin levels and delay values

v0.11

Release Notes:

• GW.py: Auto-detect the COM/serial port device name
  • The device argument is now optional!
• USB: Provide a serial-id string to the host
  • Identifier is unique to each Greaseweazle device
  • Allows disambiguation between multiple Greaseweazle devices
  • Recommended: Full flash from HEX file (embeds serial in bootloader)
• Ubuntu: Udev script now creates a /dev/greaseweazle symlink

v0.10

Release Notes:

• STM32F7xx: Multi-drive support via drive-select config option
  • Up to three Shugart drives or two IBM/PC drives
  • gw.py read|write --drive {a,b,0,1,2}
  • See the Drive Select wiki page

v0.9

Release Notes:

• Activity LED
  • Lights while a USB-issued command is in progress
  • Flashes when enumerated but idle in the firmware-update bootloader

v0.8

Release Notes:

• STM32F73xx: Various Fixes and Improvements
  • Allow Firmware Update mode to be forced via strapping Serial RX/TX
  • Fix bogus sample values at start of read flux values
  • Fix some time constants to be in units of the sample clock
• USB: Advertise USB 2.0 device descriptor

v0.7

Release Notes:

• USB: Fix end-of-stream detection on track writes
  • Writes of empty/unformatted tracks sometimes hung forever
• No Flux Area: Firmware automatically masters long NFAs during track writes
  • Generating no flux transitions does not read back as a NFA
• STM32F73xx: Initial support for new STM32 MCU
  • Two HEX files are included: Use Greaseweazle-F1-* for existing boards!
  • Single unified UPD file containing both firmware images
