RGMII Signal Connections to headers The S32R294 device supports both 3.3V and 1.8V supply and I/O levels for the ethernet interface, therefore the EVB includes support for both of these options. This can be selected by changing the connection of J64, as shown in the table below.

For flexibility, the FlexRAY transceiver is connected to a FlexRAY connector P1. By default the FlexRAY interface is not enabled. To enable the FlexRAY interface the jumpers detailed in Table 6 need to be placed.
- Page 14 An external 256Mbits Serial NOR Flash memory ( MX25U25645G, U21) is connected to S32R294 via the QSPI interface. Since there is no internal Flash inside of the MCU, code can be stored in the external flash, then loaded into SRAM in MCU after power-on over QSPI interface.
