Follow these steps to connect and power on the board
1. Carefully unpack the S32K312EVB-Q172 and observe ESD preventive measures while handling the K3 development board.
2. Connect necessary cables between host PC and EVB board prior to applying power to the EVB.
3. The power-ON sequence for the EVB must be as follows:

a)
- The power switch -SW1 must be in OFF position before to the EVB be connected to an external power supply.
b)
- Once the power switch -SW1 is in OFF position, then the EVB can be connected to an external power supply.
c)
- Now the power switch -SW11 can be changed to ON- position.

4. When power is applied to the EVB, three orange LED’s adjacent to the voltage regulators show the presence of the supply
voltages as follows:
•LED D2 Indicates that the 12.0V is connected to the EVB correctly.
•LED D4 Indicates that the 5.0V linear regulator is enabled and working correctly.
•LED D5 Indicates that the +3.3Vlinear regulator is enabled and working correctly.
Figure 3. S32K312EVB-Q172 –Power supply Input and LED power indicators
If no LED’s are illuminated when power is applied to the EVB and the regulators are correctly enabled using the appropriate
jumpers, it is possible that either power supply is not connected properly, or the voltage level is lower that the specified [+12.0V
to ≥2Amps].
Note that the fuse will not protect against one of the EVB regulators being shorted. If this happens, damage is likely to occur to
the EVB and / or components.
5. The board is ready to use now.
7 S32K312EVB-Q172 - Power supply
The EVB requires an external power supply voltage of between to +12V/≥2A. This allows the EVB to be easily used in a
vehicle if required. The 12v input is on the EVB is used to supply a FS26/SBC –U1, the power management IC controller
provides +5.0V, +3.3V and +1.5V, for the different power configurations of VDD_HV_A, VDD_HV_B, V15 and other
interfaces

8.1 RESET Switch and LED indicator
The RESET switch [SW2] provides for manual application of the RESET input signal. The S32K3 MCU will drive the RESET signal to
reset the EVB board peripherals. The RESET LED indicator [D22] will be ON for the duration of the RESET signal. This operation indicates
the S32K312 MCU is in the Reset state.

Connector
J50
This small 20-pin (0.05") connector provides access to SWD, SWV, JTAG, and ETM
(4-bit) signals available on a Cortex-M3/M4/M7 device.
A 20-pin header (Samtec FTSH-110-01) is specified with dimensions:
0.50" x 0.188" (12.70 mm x 4.78 mm).
NOTE - JTAG –TRACE Signals
Due that the MCU ports used for the trace signals also are shared with other
interfaces. It is important to isolate these signals/interfaces for the J4-Cortex Debug
D ETM connector.
