Hi,
it seems like that this version of SDK is only compatible with the suggested NDK. With the newer NDK it wasn't even possible to properly assign an IP address.
We got the Ethernet/IP example to run and took it as a reference. We added the client example (for elf devices from the NSP) on top and the HTTP server works. Only minimal changes to the client example were necessary.
So your suggestions were right.
Thanks a a lot,
Timo
