Version 2.0

Image release: pynq_z1_v2.0

Documentation updated: 18 Aug 2017

  • Overlay changes
    • New logictools overlay
    • Updated to new Trace Analyzer IP in the base overlay
  • Repository Changes
    • Repository restructured to provide better support for multiple platforms
    • Repository now supports direct pip install
      • is now deprecated
  • PYNQ Image build flow now available

  • Pynq API Changes
    • pynq.lib combines previous packages: pynq.board, pynq.iop, pynq.drivers

    • The pynq.iop subpackage has been restructured into lib.arduino and lib.pmod

      For example:

      from pynq.iop import Arduino_Analog

      is replaced by:

      from pynq.lib.arduino import Arduino_Analog
    • Overlay() automatically downloads an overlays on instantiation by default. Explicit .download() is not required

    • DMA driver replaced with new version

      The buffer is no longer owned by the DMA driver and should instead be allocated using Xlnk.cma_array. Driver exposes both directions of the DMA engine. For example:

      send_buffer = xlnk.cma_array(1024, np.float32)
      # wait dma.wait_async() also available in coroutines
    • New Video subsystem with support for openCV style frame passing, color space transforms, and grayscale conversion

    • New PynqMicroblaze parent class to implement any PYNQ MicroBlaze subsystem

    • New DefaultIP driver to access MMIO, interrupts and GPIO for an IP and is used as the base class for all IP drivers

    • New DefaultHierarchy driver to access contained IP as attributes and is used as the base class for all hierarchy drivers

    • New AxiGPIO driver

  • Linux changes
    • Addition USB Ethernet drivers added
    • Start-up process added to systemd services
  • New Python Packages
    • cython
  • IP changes
    • Updated Trace Analyzer, deprecated Trace Buffer
    • Updated Video subsytem with added HLS IP to do color space transforms, and grayscale conversion
    • Added new logictools overlay IP: Pattern Generator, Boolean Generator, FSM Generator
  • Documentation changes
