Thanks, that document is very helpful. I set up TCP Blaster as a client, not a server, just because it was easier for me to send data from Linux with netcat. I'll try it as a server, I just have to look up the right netcat params.
I am not sure if you should not use netcat. When you build apps/examples/tcpblaster it will build the matching host side of the test. Best to use the version generated by build/apps/examples/tcpblaster. It will leave the host program in the apps/examples/tcpblaster directory. The host program will be called either tcpclient or tcpserver, depending upon how you have the example configured.
I am glad to hear from you that's your experience was that NuttX is limited by the network. That's great! :) I do think high speed transfers should be possible using Ethernet over USB and I would love to get it working at close to the link speed of 480Mbps. That would really help for the application I'm building.
The is only on Tx. The Rx side is more complex and will depending more on you application configuration.
480Mbps is NOT the link speed. That is the USB speed. The link speed will be negotiated on the network and only 10Mbit/sec or 100Mib/sec are likely. Are you expecting this to work on a giga-bit network? I suppose that will depend on the what you have plugged into the USB port. I have never experiment with a giga-bit network accessed via USB. If that is the case, then USB will be the bottle neck.
More people use RNDIS and CDC/ECM. Has anyone using either USB networks with a giga-bit network? How did it perform.
I know that Masayuki Ishikwawa has used RNDIS a lot. Perhaps he can respond.
You might also ask on the old Google forum too. There are still 300 or so people still using only the Google forum (or are inactive).
