Hi,
We are using Ti DP83867 1G phy over RGMII but we are facing issue after loading driver of that Phy we are seeing poll mac Software reset error again and again.
Please find attached pin mux with the update of RGMII and ETH RESET and INT along with logs.
Please let me know which DTS is being used for ethernet.
Thanks
Sagar

Does eth0 in /proc/interrupts get increase when trying to enable interface?
Hi Wayne,
If i am not wrong eth0 belongs to 10G PHY not 1G Phy(based on RGMII). Please confirm.
Thanks
Sagar
You are wrong. Read your own log.
Hi Wayne,
Can you please elaborate what we need to check or probe here?
Thanks
Sagar
Check the interrupt for your eth0 interface is increasing or not… if that is always 0, then it is the problem.
Hi Wayne,
We are not even able to see it. Please find dmesg for your reference. And let me know what we can do to resolve this issue.

Hi Wayne,
Can you please let me know where and what will be the file name of pin mux and gpio dtsi file after enabling the RGMII pins from pinmux config excel table?
And we are not using ETH reset pins since my phy supporting Power on reset will it impact anything?
Thanks
Sagar
Hi Wayne,
is there update on it?
Thanks
Sagar
Share us what is your result of /proc/interrupts…
Hi Wayne,
We are not seeing this parameters in terminal as well seems like RGMII is not configured properly in ORIN. Thats why i asked -

Yes, that will affect the function.
We are not seeing this parameters
Not seeing what parameter?

Read your board config and it will tell. There is no need to ask me what file name because I don’t memorize everything on Jetson… There are too many kinds of Jetson platforms. You need to learn how to check this but not ask a file name…
Hi Wayne,
Can i know what will be the impact?
Thanks
Sagar
Can i know what will be the impact?
That is why you filed this post… functionality does not work. Link is not up.
Actually i am not able to see any MDIO transaction on MDIO lines as well seems RGMII not configured properly? So-

Since you didn’t read my comment and just repeat the same question, let me repeat my comment too…

Also, check /sys/bus/mdio_bus and see if corresponding PHY driver is present or not.
Hi Wayne,
I follow this from this link-

HI Wayne,
it is not present.
Thanks
Sagar
