PPSi
This project is concerned with writing a portable PTP daemon, to be used in White Rabbit and possibly other projects. The code base should be able to build a standard PTP and an extended one, running either under an operating system or as a freestanding application on bare metal. At compile time, it can be decided about the target architecture and the “standard protocol”/“white rabbit extensions” implementation.
PPSi has been developed within the White Rabbit project.
The latest version of PPSi documentation is available at PPSi Manual October 2022.
White Rabbit Switch with PPSi has been tested against compatibility with IEEE1588 and White Rabbit protocol using ATTEST framework available from Veryx Technologies. More information is available at the White Rabbit Compliance Tests project page. The test results of the current and past WR switch firmware releases are available on WR switch release compliance tests website.
