【摘要】 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。更多还原

【Abstract】 The design of Bootload serial loading procedures was proposed. It realized one- time multiple CC2530 nodes automatically loading and firmware updating through USB bus. The design covers the whole process of the boot loader,code introduction,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.更多还原
