Ethernet over USB -zperf example for NUCLEO F429ZI board

[Masood-Salik]

Hello everyone,

I need help running the ZPERF example for the NUCLEO F429ZI board with Ethernet over USB.

zephyr/samples/net/zperf/sample.yaml

Lines 24 to 30 in f9739ab

	sample.net.zperf.netusb_rndis:
	extra_args: OVERLAY_CONFIG="overlay-netusb.conf"
	extra_configs:
	- CONFIG_USB_DEVICE_NETWORK_ECM=n
	- CONFIG_USB_DEVICE_NETWORK_RNDIS=y
	tags: usb net zperf
	depends_on: usb_device

I have configured the proj.conf by doing the above configuration. I also had to disable the CONFIG_NET_IPV6 flag otherwise mcu restart when anything is sent via Serial cmd.

The RNDIS network is discovered and I can set the IP. However, when I run iperf-2.0.5b-win32 in server mode on my Windows 11 and send zperf tcp upload 192.0.2.2 5001 10 1K 1M on the board, I get the error

TCP upload failed (-116)

. The connection is not established for TCP. Also getting error for UDP upload failed (-115) Can anyone help me understand what the problem might be?

Thank you in advance for your help.

@Desvauxm-st Can you have a look ?

@Masood-Salik Please consider that @Desvauxm-st will look into this issue when time allows. Also note that there is no issue identified, I don't think this deserve to trigger this whole set of person.
Please understand that all of these guys also have their own concerns and priorities. If they should be involved each time someone struggles to set up a sample, this would quickly not scale and prevent progress on the project as a whole.

@Desvauxm-st Any update?

If you are using picolib then the -116 errno would mean ETIMEDOUT, so my guess is that the connection to Windows was not successful.
The issue could be for example wrong IP addresses used between Zephyr and Windows, or various other connection issues.
