Even the PRUs, which I want to put into operation, are supported by FreeBSD. But unfortunately i do not have a clue, how the driver is intended to be used. For linux there is some API/docu to load/start/stop and communicate with the PRU. > > Did anyone put the PRUs already into operation with FreeBSD and could give me a hint how this is done? There's a work in progress PRU library: https://bitbucket.org/rpaulo/libpru And a program to upload binaries to the PRU: https://bitbucket.org/rpaulo/pructl These don't have documentation yet and you have to build them yourself, but that should be straightforward. You can use the assembler from ports: devel/pasm. -- Rui Paulohelp
