[LS1046A] mdio-tools on ubuntu OS

charleshuang — Tue, 20 Aug 2024 07:59:44 GMT

Hi NXP Team,

I can't use https://github.com/wkz/mdio-tools in LSDK20.04 on LS1046A。

I have tried versions 1.1 to 1.3, and the result is the same.

Can you help me confirm this issue?

mdio-tools cannot used on DPAA Ethernet ports.

We use mdio_proxy_module in LSDK 21.08.

mdio_proxy_module:

url: https://github.com/nxp-qoriq/mdio-proxy-module.git

tag: LSDK-21.08

However you need to port the source code to make it suitable for your version Linux Kernel.

To find out mdio bus name, you need to do the following.
find /sys | grep -i class|grep -i mdio
Please refer to my following log.
root@localhost:~# find /sys | grep -i class|grep -i mdio /sys/class/mdio_bus

For PHY registers read and write, you could clone phytool and build it from: https://github.com/wkz/phytool.git

Then copy phytool to the target board to use it.

In the default Linux Kernel driver, phytool write is not supported, you need to apply the attached patches.
