SK-AM62: network-online.target seems to take up to couple for minutes to complete

Mitesh Hiran

Part Number: SK-AM62

Hello, I am running application that needs network on at least one ethernet port to be configured (meaning to have IP address) and on debug looks like the systemd-networkd-wait-online.service takes 20 to 40 seconds on back to back reboot and sometimes goes up to couple of minutes.

Have tried adding --any, -i eth0, -o carrier, and it seems to take always more than 20 seconds.

with timeout=5, it of course timeout after 5 seconds but not sure if any section of the network is not set up properly.

What is the best way to constraint this service to just have service completed to indicate system at least as one link up with IP address?

Thanks

Hi Ashwani, we see this on both Eth0 and Eth1.

I am using SDK v8.6

Hi Mitesh,

Means, you are using MCUSDK (RTOS) and both ports of CPSW. correct ?

Can you help me with the setup and steps to reproduce the issue ?
Which example from SDK I can use to reproduce the issue ?

Best Regards

HI Ashwani, no no we are just using the SDK and not then RTOS.

Just booting Linux using the two Ethernet port we see this time delay of around 20 seconds from the online target service.

Would like to understand why is this the case in both 100MBps and 1GBps link connections.

Thanks

I am unable to test this on eval board SK-AM62 but would assume to be the case, where the online target service takes around 20 seconds to complete.

Thanks

Sorry, I do not understand, what is online target device?

Means, you are working o your custom board which have AM62x SOC ?

HI Ashwani, yes working on 08.06.00.42.

I can't use eval as I am currently testing this on custom board.

In terms of the online target device, this is part of the Linux service wait on.

example in a service file:

[Unit]
After=network-online.target
Requires=network-online.target

Hi,

I apologize as I have missed your query.

I looked at the systemD log you provided and I am not sure how we can help with shortening the time of the various services startup. TI support is limited to the CPSW driver only. SystemD is a higher level user space tool that is above the TI CPSW driver.

Are you seeing an issue with the interface sending and receiving packets?

Best Regards,

Schuyler
