STM32H7 Ethernet and LwIP: No data seen when running iperf 2.0.8

[Egolt.1]

Hello,

Question related to post "How to create a project for STM32H7 with Ethernet and LwIP stack working":

I downloaded, build and load the STM32H723_Nucleo_ETH to my Nucleo after I changed the board IP to 192.168.0.160 to fit my network and I run an iperf 2.0.8 (I was not able to find 2.0.6 as mention in the code) on my windows PC with IP 192.168.0.32.
But, I don't see any data on the PC running iperf in server mode on port 5001.
I check with Wireshark also and I don't see data other then a single line:
1225 27.865374 192.168.0.160 192.168.0.34 TCP 60 52432 → 5001 [SYN] Seq=0 Win=5840 Len=0 MSS=1460
Ping from 192.168.0.32 to 192.168.0.160 works fine.
Any help will be appreciate.
Thanks
Eyal

Sorry? which exactly project or example? Is it from the Cube package or from here?

Anyway, better use a small private network for testing. Avoid connecting the Nucleo to your office or home LAN. Just your PC [and a sniffer].

Hello Pavel,

I referred to this repository that was mention in this knowledge base article, in it there is a project for the Nucleo H723 and I tried to use this project for measuring throughput with iperf as mention in the project documentation and code.

Do you have any other suggested way to measurer Ethernet throughput with the STM32?

Thanks,

Eyal
