stm32mp157a + ar8035 ,eth0 can't work properly

[xxiao.1]

sdk: 3.0.0 ver

kernel: 5.10.10

Ethernet cannot be connected in the kernel of version 5.10.10, but version 5.4.31 works normally

The Ethernet related device tree is as follows：

dts as follows；

Hi,

did you progress meanwhile ?

from the log above, seems ethernet if OK.

Did you cross check the DTS potential changes between ecosystem V3 (kernel 5.10) and V2 (kernel 5.4) ?

• V3: https://wiki.st.com/stm32mpu/wiki/Ethernet_device_tree_configuration
• V2: https://wiki.st.com/stm32mpu-ecosystem-v2/wiki/Ethernet_device_tree_configuration

I know that there was some changes regarding driving reset signal. Did you use it on your board ?

Regards.
