摘要
通过深入研究ADI Blackfin DSP加载过程,提出一种在线升级方案。通过编写的上层下载程序和DSP Loader程序,可在DSP启动、判断特定条件后,进入运行模式(启动应用程序)或下载模式。在下载模式下,DSP的Loader会接收待下载应用程序数据,将其下载到外部Flash指定的地址中,从而方便、快捷地实现程序升级。
An online upgrade method is designed for ADI DSP Blackfin53X through deep learning its loading process.With the downloading APP and DSP Loader,we can determine which mode the DSP should run(APP mode or download mode).In download mode,DSP loader will receive the bootcode from APP,and then download the bootcode to Flash,which the address is assigned.With this method,the IAP is realized conveniently and easily.
