Re: How to get LED triggers for ethernet activity?

Hi
I like to know how i can assign any GPIO pin for ethernet activity indication by connecting LED with that.
I need to have link and data LED connected with GPIO pins of Omega2+.

I tried system amber led to show WIFI activity using
echo phy0rx >"/sys/class/leds/omega2p:amber:system/trigger"
but didn't work even. Invalid argument error came.

Please explain.

Thanks
Suman
