I am porting the openpowerlink on the STM32F microprocessor as Controlled Node.
My first question is openpowerlink stack is compatible with LWIP or not ?
In particular, May I use the LWIP to handle the ethenet packet or I need to use direct Ethernet packet handling using ETH_MAC ?
Let me know

Hey Marco, in case you are still looking into this,
- a typical controlled node (CN) in openpowerlink uses its own DLL to create and schedule frames. This is for maintaining the timing restrictions necessary for the real-time behavior in the network.
That said, for an experimental demo, it does support using the underlying network stack to quickly setup a CN:
- off the shelf the openpowerlink release package does not include the port for lwip (only Linux and Windows networking with ip tunneling).
- But it will work with lwip with the porting of the CAL and networking abstraction layers (for the rtos and lwip combination).
Feel free to reach out if you need any help.
