DP83822I: Ethernet is not working in petalinux 2019.1

shilin S I

Part Number: DP83822I

While using DP83822 even after enabling in-built drivers for PHY and DP83822 in petalinux 2019.1, the Ethernet interface is not getting up. Has anyone faced same issue after even enabling in-built drivers in petalinux? Is there any configurations for enabling this interface?

Hi,

Can you please probe the PHY state thru MDIO/MDC access to see the link status is up or not ?

I can access PHY state through mii reg in uboot. The link is not up there. After booting up the kernel while observing the boot log ,the driver gets probed but still link is not up.

Hi,

Can we say the issue is due to the PHY link not coming up ? it's not related to PHY driver.

For PHY link-up, can you please check following:

1. Clock on RX_CLK ?

2. Probe MDI pins and check for FLP pulses
