Hi! I’m trying to use KSZ9896 as PHY on Jetson Xavier custom board. What should I do to bring up ethernet on my board. Do I need KSZ9896 drivers or I can use default drivers and just config device tree? KSZ9896 connected over RGMII interface on port 6 and MDIO bus.

Hi, Please check this thread. [image] how to replace net PHY of Xavier Jetson AGX Xavier dear nvidia， how to replace net PHY of Xavier？ how to modify dts？where is net phy driver file ？ thanks

Our network via KSZ9896 worked after the following actions:

Configuring the device tree.
SPI bus connections to KSZ9896.
Installing the KSZ9896 driver.
Configuring KSZ9896 via the reg_bin utility.

Files in atta0.zip (1.9 MB) chment. The device tree must be adapted to your board.
