We follow the way to open QCA7000 driver in linux config.

After the linux configuration and rebuild the kernel, we could not see the ethernet interface in our platform.

The console log and dts file as the attachment.

What Linux version are you using? How is this chip connected to the Sitara device?

Using SPI interface. We want to operate QCA7000 as a ethernet interface.

Can you probe and confirm if SPI data is being transmitted thru the SPI interface? Make sure SPI is configure per instructions found in the SPI chapter of the Processors SDK.

I already set the QCA7000 as the follow configuration in dts file.

However, after add the QCA7000 as the ethernet interface. The original two ethernet ineterface was not to enable the interface.

If set the QCA7000 ethernet up, the system hangs.
