Hi Justin,

The customer is looking for the drivers and user guides for the implementation on ARM Cortex M4 Controller.

He noted that they are not using hardware bootstrap configuration so he wants to know how to configure RMII using SMI.

Danilo

Hi Danilo,

You can find the register information in the DP83822I datasheet. In order to set the device into RMII mode you need to configure the bits 0x0017[5] and 0x0017[7].

We also offer Linux drivers for the DP83822I under the software development tab of the DP83822I product folder.
