Before writing the configuration flow, design and determine the device configuration including:
The device configuration flow is as follows:
1. Download the firmware binary file to the embedded processor and check if the chip has been initialized to a state that user can access it.
2. Configure the PMON timebase, if you want to use the internal timer.
3. Configure the PFP including the following parameters: link id number, buffer size, cut through/packet mode, backpressure threshold, burst size,
4. Configure the SPI4 interface, including ingress/egress logical port mapping, calendar configuration, interface initialization and enabling, and
5. Initialize auxiliary interface memory/generic mode, if you use auxiliary interface.
6. Initialize PRBS module, if you use PRBS insert/extract.
7. During the traffic test check the device status by reading various information, such as PMON statistic information, PFP/SPI4 status information
Note: Please refer to the programming guide for device configuration examples.
