CMSIS-DAP debug support

This section describes how to enable CMSIS dap debug support for your TWR-LS1021A board.

NOTE

The TWR-LS1021A 700-28040 board comes pre-programmed with

CMSIS-DAP firmware.

To enable the CMSIS-DAP debug support for TWR-LS1021A 700 revX3/X4 board, follow these steps:

1. Download the CMSIS-DAP firmware and documentation from

http://compass.freescale.net/livelink/livelink?func=ll&objId=232410365&objAction=browse&vi

ewType=1

2. Plug in power to the TWR-LS1021A 700 revX3/X4 board.

3. Hold down Reset button (SW1) while plugging the PC USB cable into the J5 USB connector on the

board.

4. On Windows, the board will be mapped as a Mass Storage Device under a volume labelled

BOOTLOADER

5. LED D2 will blink in green on the board to acknowledge it is in bootloader mode.

6. Copy the binary files downloaded in Step 1, into this new volume, BOOTLOADER.

7. When the binary files are finished copying, the LED D2 will start blinking with a higher rate.

8. Unplug the USB cable from the board, then plug it back to the power cycle module.

9. Set SW2[8] to OFF.

You are now ready to connect to your board through CodeWarrior for ARMv7.

NOTE

For Windows platform, you need to install mbed USB driver. For
