Tool/software: Linux

Hello TI Team,

In SDK v04.02.00.09 and I do the 1st ifconfig to start ethernet, it will be failed. And then I do 2nd ifconfig, it will be work. The relative message is as below.

ifconfig eth0 up

Hi,

Based on the original question the outputs that are posted are showing everything looks OK. The last posted shows an IP address on eth0 and that the PHYs are being identified in the boot log. Currently it does not look like you are still experiencing the original posted issue.

Best Regards,
Schuyler

Hi,
The original issue is still existed. The information posted is after doing 2nd ifconfig to enable eth0.

Hi,
Could you please post the full boot log from power on all the way to the log in prompt? I would like to see ifconfig after you log in, please do not do ifconfig up. Please make the log file an attachment, the paste method will make this thread pretty long to read. The boot log is showing the PHYs as being correctly identified, but I need to see the network interface init process that gets printed in the boot log. Above you mentioned that this is the file system from the SDK, I want to confirm that and the interface being attached is eth0.

Best Regards,
Schuyler

Hi,
Thanks for the log. Looking through it I don't see a user space being initialized here, it looks like the system is booting to a single shell or perhaps busybox. The user space initialization will typically setup some sort of network management that will start the process of trying to obtain an IP address. With the system you have there until the ifconfig up is performed there will not be an ip address. This looks to be a user space initialization or design issue and not really a network issue since once the ifconfig up is performed an address is obtained.

Best Regards,
Schuyler

Hi TI team,

Continue this issue as below:

Now we use the TI root file system and test. We can also get the ethernet error information(more log in attachment).

Hi,
While I see the PHY driver identified as being on the MDIO bus I don't see the PHY driver printing out a message indicating it has initialized until after the ifconfig down up sequence. This line below normally happens as part of the boot sequence.

Are you using the default kernel configuration that comes with the TI SDK?

Hi TI Team,

We do not use the default kernel configuration and our kernel configuration is in attachment.

Hi,

Can you try the default kernel configuration that comes with the TI SDK as a means of debug? Would there be reason or reasons this would not work? The PHY drviers that you are using should be configured to be built in modules in the TI kernel.

Best Regards,
Schuyler
