Original question:
I am using AM3352 with Marvell Phy.
I have connected with internet and till 100 Mbps, it is working correctly. When connecting with greater than 100 Mbps, it is showing 1000 Mbps but with speed test ookla, it never shows greater than 100 Mbps. Our Broadband speed is showing 220 Mbps on PC.
Please help me to enable Gigabit ethernet.
What OS do you use on your AM3352 board?
This forum only supports TI Processor SDK releases, but I am forwarding your query to our Ethernet expert for any comment.
Hi,
Could you provide the console log, and the results of ethtool for the interface that is connected? Example would be:
ethtool eth0
Could you also provide a little more detail on the environment that you are testing with and how you are testing? We typically use iperf between two linux devices. I am assuming that you are testing with a server on the web?
Regards,
Schuyler
Hi,
Please find attached ethtool and dmesg logs.
I am using typically 1000 Gigabit Cat 6 cable with Cisco Switch and through that internet coming up. On PC, it is showing 220 Mbps with OOkal Speedtest but with my device, it is showing from 60 - 85 Mbps. One more thing when I am connecting the internet of the lower speed of 50 Mbps or around, it is showing correct speed or around.
I have used Linux kernel 4.4.16 with default uboot. Also, marvel Phy with 10BaseT to 1000BaseT support.
I am testing directly with the Internet. I have created a python script with speedtest based python APIs. I have used this script to check internet speed on both PC and AM3352 device. This script is showing correct speed with Ubuntu on my PC but not on the device.
You can check speedtest-cli with github.com/.../speedtest-cli.

Hi,
Thanks for the logs and the additional explanation. TI will only be able to support a local connection or immediate link partner between the AM3352 device and a PC for example. TI is only able to support the CPSW driver and it's interface to the Linux kernel. Connecting to the internet too many variables that affect throughput will come into play.
The first thing I see looking through the ethtool output is puzzling and points to some possible HW issues. Ethtool is not showing a link partner and the boot log provided does not show the CPSW establishing a link up status. Are there other network interfaces on the board such as USB?

Hello,
Sorry, I have not seen logs perfectly. Please find attached logs. This time, I have attached cable all time.
Yes, We have a wireless interface with USB.
One more thing, If Hardware issue is there, then Can you describe where it can be?

Hello,
One Update.
We have taken new broadband of 500 Mbps and with that, I have tested AM335 device. With SpeedTest script, it is showing 130 Mbps around.
So, there is no issue as mentioned earlier but still, there is an issue with speed.
I have checked the same connection with my PC and it shows around 450 Mbps and AM3352 device shows 130 Mbps.
So, My question is why this much difference (almost 3 times) between PC and AM3352 device?
Regards,
Sandip Rakhasiya
Hi,
The difference in network throughput is due to the differences in processors. A PC will always have more network throughput capability than the AM3352.
Please note that comparing the AM3352 to a PC is not and cannot be compared in a 1 to 1 fashion. Most PCs are multi-core and much more complex devices when trying to compare to the AM3352 which is a single core device. Please also consider that PCs use network adapters that have network acceleration in them that increases network throughput. All network traffic on the AM3352 has to be processed by the cortex-A8 processor, there is not any network offloading like there is in a PC.
Another point to take into account is the speed that the AM3352 is being run at. The link below is to a performance guide and there is a section on network throughput. Depending on the speed that the AM3352 is operating at will have a direct impact on throughput. The board used in the performance guide is running at 1GHz, that would yield roughly 350-370Mbps as an iperf client (sending data).
To summarize there are several factors such as processor speed, number of interfaces active(CPSW and USB here) that will impact the network throughput.
Best Regards,
Schuyler
