AN12149 has a hyperlink to AN12149SW:
The newest 2.3.1 PTPd source code still exists much code which adapts to the desktop operating system, so this application note also modifies many other files, most of which are removing the code that do not adapt to the RTOS. For all these changes, see AN12149SW.
This hyperlink is broken. I've also had no luck manually searching for this document. Is it still available?
By email I've received AN12149SW, however the version sent to me appears out of date. It is using ptpd v2.2.2, whereas the latest AN12149 references ptpd v2.3.1:
The PTPd package version now used in this demo is version 2.3.1.
There are many important bug fixes between these two versions of ptpd. Is a newer demo using ptpd v2.3.1 available?
