We have just released v4.1 of the WR PTP Core. You can find all the links to download the reference designs binaries and documentation on our release wiki page.

This release contains mainly fixes to the previous v4.0 stable release:

• fixed PCIe reset for standalone operation
• fixes to p2p mode in PPSi
• fixed Rx termination scheme for Spartan6 PHY which made WRPC unable to work with some SFPs
• fixes and updates to HDL board and platform wrappers

and also some new features like:

• new Wishbone registers bank available to read WRPC diagnostics from user application
• new wrpc-diags host tool to read diagnostics over PCIe or VME
• built-in default init script that loads SFP calibration parameters and configures WRPC in Slave mode
• new document WRPC Failures and Diagnostics

Thank you for all the bug reports and contributions. As always, we encourage you to try this fresh release on your boards.
