2. Get Hardware

This section covers the components and features of the S32J100 EVB. Refer to Figure 1 and Figure 2 to become familiar with the layout of the board.

2.1 Board Features

Figure 1 below labels the features of the S32J100-EVB-V2.

Figure 1. S32J100-EVB-V2 Features and Layout

Note: The S32J100-EVB-V2 is an updated version of the S32J100-EVB. Both boards are functionally identical and support the same S32J100 features and use cases. The main hardware difference is the power management integrated circuit (PMIC): the original board uses the NXP VR5510, while the newer version pictured includes the newer NXP FS25 PMIC.

3. Build and Load

This section will walk you through the steps to configure, power, and begin working with the S32J100 EVB.

3.1 Optional Heat Sink

Under normal operating conditions, it is not necessary to mount the heat sink.

To mount the heat sink, place the thermal pad on the S32J100, position the aluminum heat sink over the thermal pad, and press the mounting pins until they lock.

3.2 Default Configuration

The board can be configured using the SW3 dual in-line package (DIP) switches. Table 1 details the functions of each switch. Set the board to default when getting started.

Table 1. SW3 Board Configuration DIP Switch.

`SW3` DIP	Function	Off State	On State	Default
`SW3.1`	Peripheral Component Interconnect Express (PCIe) clock source	Local oscillator	Mini Cool Edge input/output (MCIO)	Off
`SW3.2`	PCIe clock output to MCIO	Enabled	Disabled	Off
`SW3.3`	PCIe debug clock output	Enabled	Disabled	On
`SW3.4`	PCIe spread spectrum clock	Disabled	Enabled	Off
`SW3.5`	Port 0 Input/output supply voltage (VDDIO) selection	3.3 V	1.8 V	Off
`SW3.6`	S32J100-EVB-V2 PCIe mode	Root complex (RC)	Endpoint (EP)	Off
`SW3.7`	Boot source selection BOOTMOD_0	Off, on: Serial boot On, off: Boot Reset Configuration (RCON) or fuses (default)		On
`SW3.8`	Boot source selection BOOTMOD_1			Off

For development purposes, the S32J100 includes 16 bootstrap pins, referred to as parallel RCON. You will configure these pins on the S32J100-EVB-V2 using the DIP switches SW16 and SW17. Buffer connect the pull resistors only during reset. After the functional reset is released, you will disconnect the RCON pull resistors. The default configuration (run from the oscillator) is:

SW17 RCON[15-8]: 0x00
SW16 RCON[7-0]: 0xA3

Production boards do not require external RCON switch settings because the same configuration can be programmed into the S32J100 internal fuses.

3.3 Powering the Board

Use a 12 V, 1.5 A power supply with a barrel connector to power the board. If necessary, connect the included barrel connector adapter.

After connecting the power supply, you will turn on the power switch (SW15). The power-good (PGOOD) LED (D100) will light up to indicate that the board is receiving power.
