USB Boot Loader Demo 2 An example to demonstrate the use of the flash-based USB boot loader. At startup, the application displays a message then waits for the user to press the select button before branching to the USB boot loader to await the start of an update. The boot loader presents a Device Firmware Upgrade interface to the host allowing new applications to be downloaded to flash via USB. The usb_boot_demo1 application can be used along with this application to easily demonstrate that the boot loader is actually updating the on-chip flash. The application dfuwrap, found in the boards directory, can be used to prepare binary images for download to a particular position in device flash. This application adds a Luminary-specific prefix and a DFU standard suffix to the binary. A sample Windows command line application, dfuprog, is also provided which allows either binary images or DFU-wrapped files to be downloaded to the board or uploaded from it. The usb_boot_demo1 and usb_boot_demo2 applications are essentially identical to boot_demo1 and boot_demo2 with the exception that they are linked to run at address 0x1800 rather than 0x0. This is due to the fact that the USB boot loader is not currently included in the Stellaris ROM and therefore has to be stored in the bottom few KB of flash with the main application stored above it. ------------------------------------------------------------------------------- Copyright (c) 2008-2009 Texas Instruments Incorporated.
