The QorIQ T4240 development system (T4240QDS-PB) is
a flexible system that supports the 24 threads. The
T4240QDS main board is mounted in a 4U rack-mounted
chassis and the main PCB is a custom form factor.
An additional layer of flexibility for system clocking, power
distribution, and I/O multiplexing is built into the
T4240QDS board. Eight expansion slots are provided for
adding standard PCIe cards or Freescale specialized SerDes
riser cards (XFI or XAUI networking). The T4240QDS
board comes with a Linux® board support package (BSP)
that provides a comprehensive starting point for Linux
development efforts.
The T4240QDS board is available in two form factors:
• T4240QDS board installed in a chassis
• T4240QDS board as a stand-alone system
When you finish reading this document, you should be
familiar with:
• T4240QDS hardware kit contents
• Board configuration settings
• How to get started and boot the board

QorIQ T4240 Development System
Quick Start
1 Introduction
This T4240QDS quick start explains the T4240QDS board settings and physical connections needed to
boot the board. The document provides steps for configuring switches, connectors, jumpers, push buttons,
LEDs, and connecting peripheral devices.
The T4240QDS board works with an integrated development environment (IDE), such as Freescale
CodeWarrior. However, instructions for working with the IDE are beyond the scope of this document.

4 Connections and switch settings
This section explains the T4240QDS connections and switch settings.
4.1 Connection settings
In order to operate the T4240QDS and U-Boot, you need to connect different cables to the board. Some of
the cable connections are required, however, some of the connections are optional.
1. Fan cable (Required): Ensure the 3-wire cable from the pre-installed fan is connected to the 3-pin
Prod Fan header at J15.
This fan cable should already be installed in the received shipment, however ensure that this
connection is always made before powering on the system.

2. DDR DIMMs (Required): Ensure that at least three DDR DIMMs are installed, one for each of
the three DDR controllers, as shown in Figure 4. Otherwise, U-Boot will not boot. DIMMs should
be in the following slots:
— J23 - D2_DIMM #1, pre-installed DDR3 2GB uDIMM 72 bit (with ECC) Single Rank
— J22 - D1_DIMM #1, pre-installed DDR3 2GB uDIMM 72 bit (with ECC) Single Rank
— J200 - D3_DIMM #1, pre-installed DDR3 2GB uDIMM 72 bit (with ECC) Single Rank

3. Power supply (Required): If your power supply appears similar to the power supply shown in
Figure 5, perform the following steps to connect the power supply to the T4240QDS system. For
power supply setup and connections:
a) Gather the following items from the packaging:
— 750 W Magna Gold power supply w/ AC power cord, see Figure 5
— 6-pin to 8-pin +12V supply power cable adapter, see Figure 6

b) Attach the AC cable to the power supply. Note the location of the main power supply ON/OFF
switch near the AC plug.
c) The output cabling from the power supply consists of many cables, but only three of them are
attached to the T4240QDS board. Separate the three output power cables from the rest of the
cabling bundle, see Figure 7.
Figure 7. Output power cables to be separated from cabling bundle
d) Next, attach the 12 V power adapter cable to the 6-pin VGA1 connector of the power supply
as shown in Figure 8.
Note that the 2-pin part of the VGA1 connector is unused and does not attach to anything. Be
careful to attach the 6-pin end of the adapter cable to the 6-pin portion of the VGA1 power
supply connector. Also ensure that the latching mechanism of the VGA1 connector aligns with
the latching tab of the 6-pin adapter cable connector, as shown in Figure 9.
Figure 8. 12 V power adapter cable attached to the 6-pin VGA1 connector
Figure 9. Latch of VGA1 connector aligned with latching tab of adapter connector
e) To attach the power supply cables to the T4240QDS system:
– Attach the 2x4 P8 power supply connector to the EPS_BULK_12V header (J27) of the
T4240QDS board. Be careful that connector latch aligns with the latching tab of the mating
connector of the board.
– Attach the 2x4 end of the 12 V adapter cable to the EPS_12V header (J225) of the
T4240QDS board. Be careful that connector latch aligns with the latching tab of the mating
connector of the board.
– The main supply connector consists of two parts: a 2x2 section and a 2x10 section. Attach
the 2x2 section of the main power supply connector to the right-most side of the ATX24
connector (J30), and then attach the 2x10 section of the main power supply connector to the
left-most side of the ATX24 connector (J30). Be careful that connector latch aligns with the
latching tab of the mating connector of the board. Figure 10 and Figure 11 shows the before
and after images of these power supply connections.

4. Serial cable (Required): Attach serial cable to UART1_BOTTOM port of the T4240QDS as
shown in Figure 13. Attach other end of cable to the serial port of PC. This connection provides
visibility of boot activity to the COM port window of the PC. Configure the serial port of the host
PC with the settings shown in Figure 12.
Figure 12. Serial port configuration settings
5. Ethernet cable (Optional): Figure 13 shows Ethernet cable connection to the ENET TOP
connector. This ENET port is defined as FM1@DTSEC5. This connection is not required to boot
the system. However, it is useful in loading the boot images from an external boot image source.
Figure 13. Ethernet and serial connections.
6. JTAG / COP TAP (Optional): For additional development purposes, a TAP pod (such as
CodeWarrior USB TAP) can be attached to the COP/JTAG_TAP header at the location J216 on
the board. CCS software application is installed on the PC to support this system control interface.
The red cable edge should be oriented toward the left side of the connector where Pin 1 is located.
4.2 Configuring the T4240QDS in chassis
If the T4240QDS comes in a chassis, it appears as shown in Figure 14:
