USB – DFU class

The boot image is downloaded via the

USB by utilizing the DFU class (Device
Firmware Upgrade).
A Windows application exists that

connect to the DFU device (that the

LPC3152 implement in boot mode).

This application is used to download

the boot image.
Note that a special format of the boot

image must be used. For a description

of how this could be done, see further

down in this section.

NAND flash

The boot image is stored on the NAND

flash.
The boot image is downloaded into

NAND flash with the help of a special

loader application. At the time of

writing, no such application has been
created.

Creating a Boot Image

Note that this section describes how to create a boot image for the LPC313x family. The principles are

exactly the same for the LPC315x family and the exact same conversion program is used (even

though the somewhat bad naming of the program).
The first step is to create a pure binary file. This is normally done from the build output file (often an elf

or elf-compatible file).
Under a GCC environment, the command to create a binary file, named

lpc313x.bin

is:

arm-elf-objcopy -I elf32-little -O binary --strip-debug
--strip-unneeded --verbose <input-file> lpc313x.bin

Under uVision (Keil’s IDE), the command to create a binary file, named

lpc313x.bin

is as shown below.

The input file is in this case typically the output file with axf-ending.

fromelf.exe –output lpc313x.bin -bin <input-file>

The second step is to create a CRC attached boot image for the LPC3131. There is a command line
tool from NXP, bundled in the CDL package named:

lpc313xImgCreator

. See program output

explaining the command line options below.
