设计Bootload串口加载程序的方式，利用USB总线实现一次性对多个CC2530节点进行程序自动加载以及固件更新。设计中涵盖了引导装载程序的整个流程，通过代码介绍、测试环境、Bootload驱动和LED闪烁例程代码来验证Bootload的功能。经过反复程序下载测试，Bootload可用于串口加载程序，可以利用USB总线最多实现多达127个节点程序同时下载，实现自动化下载及固件更新，比传统的基于JTAG仿真器一对一的程序加载方式更加高效。

The design of Bootload serial loading procedures was proposed .It realized one-time multiple CC2530 nodes au-tomatically loading and firmware updating through USB bus .The design covers the whole process of the boot loader , code intro-duction , test environment , Bootload driver and LED flashing routines code to verify the function of Bootload .After repeated tests , Bootload can be used for loading program of serial port , with USB bus can achieve up to 127 nodes at the same time to realize the program download and firmware updates automatically , which more efficient than the traditional procedure of loading program based on JTAG .
