Integrated Switch

SoC's, such as J721E, integrate an Ethernet Switch as an chip-in-chip. The combined features of SOC and Switch IP (CPSW9G) can allow Ethernet switch to function continuously enabling unaffected switching on external ports regardless of the state of the rest of the device.

Ethernet Firmware Software Stack

The Ethernet Firmware is a FreeRTOS based application for configuration of Ethernet switch, hosted on the Cortex R5F 0 core 0 in Main domain of J721E and J7200 SoCs.

Ethernet Firmware package contains remote configuration server, resource management library, switch resident protocols, proxy layers to handle local and remote API calls and demonstration applications (EthFw Demos). The switch software uses PDK Enet and other drivers for respective IP configuration. The main building blocks of the Ethernet Firmware are shown in the following diagram.
