Switches and jumpers configuration

2 Switches and jumpers configuration

The TWR-LS1021A board have two 8-way dual in line package (DIP) switch. The default DIP switch

positions provide working set up values for the board. Check the default positions and verify the board is

operational before changing the switches. Figure 3 shows the settings for the switches with their default

positions.

Figure 3. Default switch configuration

Table 2-2 lists and describes the default switch configuration for TWR-LS1021A board.

Connecting USB UART

3 Connecting USB UART

The TWR-LS1021A board comes preloaded with u-boot only. Serial connectivity for TWR-LS1021A

board is provided through the mini type B USB connector.

NOTE

You need to install the USB drivers on the host PC before using the serial

terminal. You can get the drivers from the USB memory stick available in

the box, or, you can download these drivers from,

https://mbed.org/handbook/Windows-serial-configuration

After installing the drivers, set up a serial terminal using a PC communication program such as hyper

terminal as follows:

• Data rate: 115200 bps

• Number of data bits: 8

• Parity: None

• Number of Stop bits: 1

• Flow Control: Hardware/None

Then, select the first COM port assigned to the Virtual COM port.

4 Initial board power-up

The TWR-LS1021A board is powered through a barrel connector. This barrel should be supplied by a 5V

@5A supply. See Figure 1.

NOTE

It is normal for heatsink on the TWR-LS1021A board to become hot under

standard operating conditions.

To perform initial board power-up and LED check, follow the steps listed below:

1. Power-up the board through barrel connector.

2. Check for the completion of the reset sequence indicated by the LEDs (see Figure 1 for locations).

Table 4-4 lists a full description of the LED operation.

3. On powering up the board:

a) The LED D1 turns ON to indicate 3V3 power is present.

b) D5 turns ON then OFF.

c) Any Ethernet activity is indicated by the LEDs on the RJ45 connector.

d) D2 indicates CMSIS-DAP USB driver is loaded. If it is blinking, than the serial port is not

available. You need to power up the board at J3, than insert the USB cable on board.

The following table lists the LED operations.

Board software configuration

5 Board software configuration

The NOR flash on TWR-LS1021A board is divided into two banks. There are different images in each

banks that supports different functionality.

NOTE

TWR-LS1021A board comes pre-programmed with FLASH image.

The bank0 is programmed with RCW support for QE, and the bank1 is programmed with the RCW support

for 2D-ACE. The default is bank0.

Table 5-5 shows the TWR-LS1021A board’s switches and jumper settings for bank0 and bank1.

NOTE

If you enable the 2D-ACE, you have to use lpuart as console. The bootup

information displays on lpuart console by default. For more information on

how to enable the 2D-ACE output, refer to the 2D-ACE Display Device

Driver User Manual, available in the Yocto source ISO folder of the USB

flash drive shipped with the board.

You can also access the content available in the USB flash drive shipped

with the board, from the following location:

TWR-LS1021A OOBE demo

6.1 Connecting JTAG using CodeWarrior TAP

To connect the JTAG using CodeWarrior TAP, perform these steps:

1. Connect the JTAG connectivity unit to the TWR-LS1021A JTAG connector J12. Pin 1 is marked

on the board.

2. Switch ON the power to the board.

3. Check for completion of the reset sequence (see Initial board power-up). Ensure D5 turns OFF.

4. Follow the on-screen instructions.

6.2 Enabling CMSIS-DAP

TWR-LS1021A board supports CMSIS-DAP interface. CMSIS-DAP provides a standard access to the

Coresight Debug Access Port (DAP) of the ARM Cortex microcontroller through USB.

TWR-LS1021A board is implemented with CMSIS-DAP as an on-board interface chip, that provides a

direct USB connection to the debugger running on your host machine on one end, and the JTAG connection

to the target device to access the Coresight DAP on the other end.

To enable the CMSIS-DAP on your TWR-LS1021A board:

1. You have to change, SW2[8] = 0.

2. Make sure that your CW TAP device is not plugged in.

3. Attach the micro USB cable to USB serial connector, J5.

This provides serial connectivity and CMSIS-DAP connection (optional).

For detailed setup procedure, refer to the CodeWarrior Development Studio for QorIQ LS series - ARM V7

ISA Getting Started Guide (CWARMV7GS) from the following location:

http://cache.freescale.com/files/soft_dev_tools/doc/quick_ref_guide/CWARMv7GS.pdf

7 TWR-LS1021A OOBE demo

OOBE is an out-of-box-experience demo program which shows wireless networking, graphics and audio

playing functionality of TWR-LS1021A. Image files for the demo are available in the SD card shipped

with the board. You need to insert the SD card into the board to run the demo.

For detailed instructions to run the demo, refer TWR-LS1021A OOBE Demo Quick Start Guide.pdf under

\OOBE-demo\ folder in the USB flash drive shipped with the board.
