Getting Started

Quick Started

Just copy all the files in ./ready_to_download/sd_card/ into the FAT partition of SD_card, and start the device.

Started from Source File

1. build the vivado project

Download the repository:

$ git clone https://github.com/maxluck518/ons45-app53-ref_ofshw

Open Vivado 2017.4 and move into the dir downloaded before, then run the following tcl command:

$ source ./onets_7045_8x_ref_ofshw.tcl

Wait until the script completed.

2. Generate boot.bin

1. Run Synethesis,Implement and Generate bitstream steps in Vivado;

2. Wait until the Steps completed,Launch Vivado SDK to generate boot.bin and devicetree.dtc

For more details, please refer to the documents: UG973

SDNet Usage

RTL Design

Currently, the project only support for only 1 action for packet forwarding.

Parser

Extact the tcp/ip five-tuple(dst_ip,src_ip,proto,dst_port,src_port)

Lookup Table

key (phy_src_port,dip,sip,proto,dport,sport)	mask (wildcard_for_key)	value (phy_dst_port)
112 bits	112 bits	8 bits

Action

Based on the value got from the lookup table, Each packet can be sent to the specific phy_port.

For more about SDNet : UG1252, UG1012

Software Agent

The Software Agent is used for downloading flow_entry to the lookup table in SDNet.

Quick Started

Use the Prebuild app download_flow_entry in ./ready_to_download/tools/

1. Create the table_entry_file

Create :

$ touch test.txt

Edit :

$ vim test.txt

2. Download the table_entry

$ ./download_flow_entry test.txt

For more details about the flow_entry format: flow_table
