TDA4VM: Ethernet packet loss

YU Guolei

Part Number: TDA4VM

hi ti

On the sdk8.2 Linux platform, I use A72 core to directly drive cpsw2g.

However, when I use iperf2 to test the packet loss problem,

I find that the packet loss rate is about 2%, and modifying the buffer size has no effect

thanks

Correction: iperf3 is used. I tried to modify the buffer size, but it didn't work

We use bcm89836 with Linux direct drive

Guolei,

can you check your iperf3 command on both sides, if you are using udp packets, the protocol allows packet loss.
