where to find the code of "User Space IGH EtherCAT" in real-time Edge software release?

[bsdamon]

in real-time Edge software release note v3.2, there mentioned "User Space IGH EtherCAT". but in yocto guide or user guide document, there is no related information.

https://docs.nxp.com/bundle/RN00161/page/topics/release_notes.html

is the "User Space IGH EtherCAT" open-source? if not, how to get it?

thanks,

Leon
