Hi,

I have asked the development team about this, and will get back to you.

Best regards,

RE: Run throughput test using iperf2 TCP on nrf7002 DK

When I increased the packet size, i got the following warning message

<wrn> net_zperf: tcp_upload: Packet size too large! max size: 1024

I did somehow get the throughput test to execute with no errors by modifying the iperf command to

iperf -s -i 1 --len 1024 -w 24k -t 20

Is it possible to change the prj.conf where I don't have to change the iperf server command?

Hi,

It seems like the program is trying to allocate a packet that is too large.

packet allocation failed, len=1460

Increasing CONFIG_WIFI_ZPERF_PKT_SIZE should fix this, for example:

CONFIG_WIFI_ZPERF_PKT_SIZE=1500

Best regards,
Marte

Hello,

I increased with TX and RX buffers like you suggested, I now get an packet allocation failed error.

Here is the logs:

RE: Run throughput test using iperf2 TCP on nrf7002 DK

Marte Myrvold — Tue, 25 Apr 2023 11:42:49 GMT

Hi,

You need to increase the TX and RX buffers.

CONFIG_NET_PKT_RX_COUNT=32
CONFIG_NET_PKT_TX_COUNT=32
CONFIG_NET_BUF_RX_COUNT=32
CONFIG_NET_BUF_TX_COUNT=64

This should solve the packet dropped issue.

Best regards,
Marte

Hi,

Since packet cloning fails, you are most likely running out of packet buffers. This means there is a buffer leak somewhere.

Can you enable Zephyr's network shell so you can observe the buffers?

In prj.conf set the following:

CONFIG_SHELL=y
CONFIG_NET_SHELL=y
CONFIG_NET_BUF_POOL_USAGE=y
CONFIG_NET_DEBUG_NET_PKT_ALLOC=y

Then you can use the commands net mem and net alloc to see information about network memory usage and allocations.

Can you share the full log from the device?

Best regards,
Marte

RE: Run throughput test using iperf2 TCP on nrf7002 DK

Thank you for replying. I miswrote the question. I did set CONFIG_WIFI_ZPERF_PROT_UDP to n. The command I used to run iperf I did the following:

iperf -s -i 1 -P 1

I added the -P flag since I only want iperf to run for one client and exit. When I ran the test and check the logs, I noticed the iperf test starts, but the logs display several of the same messages during the test run:

<wrn> net_conn: conn_raw_socket: pkt cloning failed, pkt 0x20052cc8 dropped

Hi,

[quote user=""]I set CONFIG_WIFI_ZPERF_PROT_UDP to y[/quote]

You must set CONFIG_WIFI_ZPERF_PROT_UDP=n to use TCP.

What command are you using to run iPerf? For TCP you must use the following:

iperf -s -i 1
