Hi Dongcan,

Are there more prints on Linux beyond this line? Is the linux finishing to boot successfully? The error seen on the R5 side is an expected print and is a negative test included in the application to prevent linux from registering to reserved mcast addresses.

Can you please check the ifconfig after the boot is successful? Can you also confirm which document are you following to enable linux client for am62p?

The document which contains the details of EthFw client initialization and setup is here: software-dl.ti.com/.../CPSW-Proxy-Client.html

Thanks and regards,
Teja.

Hi Teja,

Thank you very much for your support.
I have enabled the TAP interface application and launched the launch_tap.service successfully.The tap0 interface is created and the tapif application is running normally.
However, the network behavior is still the same as before:I still cannot ping the remote device, and there is no response.

--file=ethfw_server.release.appimage.hs_fs --operation=flash --flash-offset=0x80000

Is this firmware sufficient for the TAP interface to work?
Please help me clarify these.

Hi Dongcan,

dongcan Zhi said:

If I use the TAP interface application, do I still need to load the kernel module ti-cpsw-proxy-client.ko?

Yes. The TAP interface is a helper module for the Ethernet Proxy client for Linux. The proxy client is responsible for unicast and exclusive multicast messages, and the TAP interface is to handle the shared multicast and broadcast messages. 

dongcan Zhi said:

Is this issue related to the firmware running on the R5-core?

Flashing WKUP-R5 with EthFw-server example should be enough to enable the communication to both linux and WKUP-R5 core.

Can you share the EthFw server logs (WKUP-R5 logs) which includes prints till you add the static IP to MAC address (including the prints which would be generated after adding the static IP). This will help diagnose the behavior better. 

Can you please confirm the version of MCU+ SDK that you are using and the Linux SDK version?

Thanks and regards,
Teja.

Hi Dongcan,

This behavior is expected, but the real life implications would render this not a viable option. If you are looking to  handle Unicast, Multicast and broadcast messages, then you need EthFw to be enabled, which needs ti-cpsw-proxy-client module as well. This enables the direct DMA channels from CPSW to A53 core with linux.

By only enabling TAP interface you are only using shared memory interface, which would increase load on WKUP-R5 and also comes with a limitation on throughput from linux, since shared memory path is resource intensive.

Are you running the default ethfw examples? Did you make any change to the appication configuration?

EthFw on this release is tested to be functional. But let us try to check if we can reproduce this issue in our setup. Please expect a response in 3-4 days.

Thanks and regards,
Teja.

• I can communicate properly by using only ti-cpsw-proxy-client.ko with eth0
• I can also communicate properly by using only the TAP interface (tap0)

I can communicate properly by using only ti-cpsw-proxy-client.ko with eth0

Are you able to get ping response as well? We would suggest you to flush the ARP table and try to ping the eth0. Please also try to run a multicast iperf as well.

CMD to flush ARP entries in Host PC: sudo ip neigh flush all

Thanks and regards,

Hi Teja,
Yes, I can successfully get ping responses using only ti-cpsw-proxy-client.ko with eth0, without using the TAP interface.

Hi Dongcan, 

This confirms that the unicast and exclusive multicast data paths are verified. Can you also try to run multicast iperf where the DuT is running udp iperf server and Host PC is running multicast iperf client? This needs both proxy client module and the TAP interface. This confirms the full capabilities of EthFw being tested.

On client side (on external pc's linux terminal)

iperf -c 224.0.0.251 -u --ttl 5 -t 5 -b 10M --bind <ip_addr> (interface ip from which you want to send shared mcast traffic)

On server side (on linux client): iperf -s -u -B 224.0.0.251 -i 1

Thanks and regards,
Teja.
