lib_ethernet change log

4.1.0

  • ADDED: Fix for out of range relocation when loading from constant or data pool
  • ADDED: Generic function to read PHY auto-negotiated link-speed smi_link_speed()
  • ADDED: New example for Ethernet traffic diagnostics
  • FIXED: Build warnings (when built with -Wextra)
  • CHANGED: Added clock pulse to end of SMI transfer, required by some PHYs
  • CHANGED: Updated function smi_configure() to work with all speed grades of PHY
  • CHANGED: Documentation updates
  • REMOVED: Application notes from examples folder. Instead see https://www.xmos.com/application-notes/
  • Changes to dependencies:
    • lib_locks: 2.3.1 -> 2.3.2
    • lib_logging: 3.3.1 -> 3.4.0
    • lib_xassert: 4.3.1 -> 4.3.2

4.0.1

  • RESOLVED: Use correct PHY1 timings in RMII hw tests

4.0.0

  • ADDED: RMII Ethernet MAC support for XCORE-AI
  • ADDED: Extended sim tests for testing RMII applications
  • ADDED: Support for running MII sim tests for XS3 architecture
  • ADDED: Support for XCommon CMake build system
  • ADDED: Exit command to RMII RT MAC
  • ADDED: Improved MAC feature documentation
  • ADDED: Tests for SMI
  • ADDED: Optional credit limit for Qav shaper
  • ADDED: Support for running MII sim tests for XS3 architecture
  • ADDED: Hardware tests for RMII Ethernet MAC
  • CHANGED: SMI re-write. Single port version now functional and documented
  • CHANGED: Moved example PHY drivers to lib_board_support
  • REMOVED: Slicekit based examples because hardware is obsolete
  • REMOVED: Support for waf build system
  • REMOVED: Support for XS1 devices
  • REMOVED: MII simple demo example
  • RESOLVED: Build warnings even when compile successful
  • RESOLVED: Qav shaper credit overflow causing negative credit on idle
  • RESOLVED: Packets might not be transmitted for 21 seconds if no transmit activity for 21 seconds (IFG timer)
  • Changes to dependencies:
    • lib_gpio: Removed dependency
    • lib_locks: 2.0.0 -> 2.3.1
    • lib_logging: 2.0.0 -> 3.3.1
    • lib_otpinfo: Removed dependency
    • lib_slicekit_support: Removed dependency
    • lib_xassert: 2.0.0 -> 4.3.1

3.5.0

  • CHANGED: Use XMOS Public Licence Version 1

3.4.0

  • RESOLVED: Fix crash caused by significant backpressure being applied to the mii_eternet_mac.
  • RESOLVED: Fix lockup in mii_eternet_mac due to bug in packet commit logic.
  • RESOLVED: Fix bug in mii_ethernet_rt_mac that would corrupt the packet length when buffers filled.
  • RESOLVED: Ensure interrupts are disabled in the RGMII low-level driver on speed changes.
  • RESOLVED: Clean up code to fix compiler signed/unsigned warnings.
  • CHANGE: Prevent packet drop from RGMII LP queue when there is no HP queue.
  • Changes to dependencies:
    • lib_otpinfo: Added dependency 2.0.1
    • lib_slicekit_support: Added dependency 2.0.1

3.3.1

  • ADDED: Function to write SMI extended MMD registers that some PHYs use
  • ADDED: Function to reset PHY by writing bit 15 of SMI register 0

3.3.0

  • CHANGE: Update dependencies
  • ADDED: Ability for the standard MII ethernet MAC to be able to provide link status notifications.
  • RESOLVED: Fix test_appdata that failed randomly due to timing changes
  • RESOLVED: Fix RT MII ethernet transmit being broken by a memory corruption caused by a race condition. It could cause random packet contents to be sent on the wire and invalid sized packets.
  • RESOLVED: Fix RT MII buffer read pointer wrapping over the write pointer and causing the MAC layer to crash when the ethernet clients were not keeping up with the packets being received.

3.2.0

  • ADDED: Ability to enable link status notifications to the client
  • RESOLVED: Fix bug which caused random crashes
  • RESOLVED: Fix bug in RT MII which caused packet to delay for 21.4s when sent after no packets sent for > 21.4s

3.1.2

  • RESOLVED: Fixes incorrect memset length on packet queue pointers array
  • CHANGE: Update to source code license and copyright

3.1.1

  • RESOLVED: Fixed issue with application filter data not being forwarded to clients of 100Mb MACs

3.1.0

3.0.2

  • RESOLVED: Improve interoperability of PHY speed and link detection via RGMII inter-frame data
  • RESOLVED: Fix 64-bit alignment of MII lite to prevent crash on XS2

3.0.1
