LPC18xx/43xx IRAM programming algorithm for the DFU Utility

Detailed Description

Example description
This programming algorithm allows upload and download of data to and from IRAM or any peripheral registers. The entire 4GB memory range is accessible.

More information on using the DFU Utility can be found at the following links:
DFU Utility information
DFU Utility production programming API

Special connection requirements
There are no special connection requirements for this example.

Build procedures:
LPC18xx/43xx example quickstart for Keil uVision4

Supported boards and board setup:
Although this example includes a build target for only the Keil 1857 board, it should run on all 18xx or 43xx boards.
Keil 1857 evaluation boards

Function Documentation

DFUPROG_REGION_T* algo_flash_init

(

void

)

Initializes device programming capability.

Returns

A pointer to the programming info structure Initializes device programming capability. Returns a pointer to the programming buffer, the programming buffer size, and a pointer to the DFU programming region/API structure used by the DFU streamer.

void dfuUtilSystemInit

(

void

)

Very minor system initialization.

Returns

none The DFU Utility setup does the minimum amount of setup as possible to be portable among different devices.
