Freescale Semiconductor T4240RDB User manual

1 Introduction
The QorIQ T4240 reference system (T4240RDB) is a flexible
system that supports the 24-virtual core T4240 processor. The
T4240RDB main board is mounted in a 1U rack-mounted
chassis. The T4240RDB supports clocking configuration
flexibility to change the device frequency. Two expansion
slots are also provided for adding standard PCIe cards. The
T4240RDB comes with a Linux® board support package
(BSP) that provides a comprehensive starting point for Linux
development efforts.
The part number of the T4240 reference design board (RDB)
system is T4240RDB-16GPA (for a board based upon T4240
Rev 1.0 silicon) and T4240RDB-PB (for a board based upon
T4240 Rev 2.0 silicon).
After reading this document, you will be familiar with:
• Board configuration settings (frequency, boot location,
and, T4240 or T4160 personality selection).
• How to get started and boot uboot and Linux.

3 Preparing board
The figure below shows the front panel of the T4240RDB.
Figure 1. T4240RDB front panel
The steps to prepare the T4240RDB for use are:
1. Ensure that the power switch is off.
2. Set switch and jumper header settings.
3. Default Configuration: CPU: 1.666GHz, DDR: 1600MHz
4. Attach an RS-232 cable between the T4240RDB UART1 port and host computer.
5. Open a serial console tool on the host computer to communicate with the T4240RDB.
6. Configure the host computer's serial port with the following settings:
• Data rate: 115200 bps
• Number of data bits: 8
• Parity: None
• Number of stop bits: 1
• Flow control: Hardware/None
7. Switch on the power button on the front side of the chassis. The board will boot and show the u-boot console messages.

6.4 Known issues
The T4240RDB has the following known issues:
• XFI: Two 10 Gbps (ETH10, ETH11) are not working; other two 10 Gbps (ETH8 , ETH9) are working fine.
NOTE
This is a limitation of T4240 Rev 1.0 silicon, and will be resolved with Rev 2.0 silicon.
7 Default boot mode
In the T4240RDB, the boot loader, by default, executes from the NOR flash.
