3.9.1 Automotive Ethernet switch
The S32G-VNP-GLDBOX has an automotive Ethernet switch SJA1110 which mainly comprises of a
configurable Ethernet switch and a programmable M7 core. Except the Ethernet ports and SMI bus port, the
SJA1110 also has a QuadSPI port, a SPI_HOST port and a SPI_AP port.
The QuadSPI port is connect the external flash.
The SPI_HOST internally connects to the microcontroller subsystem and is used to control the processor
boot, e.g. to provide a firmware image for boot or to update the flash.
