connected to the tower system). The USB data signals are connected to the on-board MCF51JM MCU
allow a connection to exist between a host device and the TWR-LCD.
In Boot Loader mode, if the USB cable is connected to a host PC, the TWR-LCD will enumerate as a
Mass Storage Device. If an appropriate compiled binary (.s19) file is placed in the root directory of the
enumerated storage drive, the TWR-LCD will parse the binary file and reprogram the main application
running on the TWR-LCD. Refer to Section 3.6 for more details.
3.6 Bootloader
The TWR-LCD includes a USB bootloader that allows simple “drag and drop” reprogramming. This
section will describe how to use the bootloader.
3.6.1 Obtaining the S19 file
The bootloader accepts srecord or S19 files that it uses to program the board. In the example
projects this file can be found in the <project directory>/bin/ folder and will end in an “.s19” file
extension. This file will get overwritten every time the project is compiled.
To create an S19 file, click on the “Standard Settings…” button on your project, and look for the
Linker category. Select “ColdFire Linker” and make sure that the “Generate S - Record File” option is
checked. Also ma ke sure that the “Max S - Record Length” field is set to 32.
3.6.2 Using the Bootloader
Connect the on-board USB connector to a Windows computer using the included mini-B to A USB
cable and press reset while holding down the BTLD push button.
The badge board will then enumerate as a Mass Storage Device. Inside the newly added storage
device, there will be an empty file named “READY.TXT”.
Copy and paste the S19 file into the enumerated drive. Upon successful programming, you will
hear two beeps from the board and the S19 file will appear on the removable drive.
