USB大容量存储设备(MSD)主机引导加载程序(英文)
资料介绍
1 Introduction
Bootloader is a small program put into a device that allows
user application codes to be programmed to the device. USB
Host bootloaders using USB mass storage device (MSD) class
were built for Freescale 32-bit ColdFire and Kinetis MCU
families.
User application codes can be programmed to the MCUs by
plugging a USB memory stick into the system. This
application note uses MCF51JM128, MCF52259 and
MK60N512VMD100 MCUs to demonstrate how the
bootloaders work in ColdFire and Kinetis MCUs.
2 Bootloader overview
Bootloader is a small application used to erase flash and load
user applications to a device. The USB Host MSD bootloader
provides an easy and reliable way to load user applications to
devices.
After a USB memory stick containing a valid s-record or
binary file has been plugged into the system, the bootloader
loads the user application code and programs it to the device.
The new user application can then be run in the device. This
application note helps the readers gain an insight into the
bootloader driver and build capabilities to develop their own
applications using the bootloader.
