DSP28335在线升级利用bootloader来实现对dsp28335芯片的固件进行升级，可应用在各个场合，应用领域十分宽泛。只要是dsp28335芯片都可以实现，理论上也可实现dsp其他芯片的固件升级。内容:bootloader程序+上位机程序，利用can通信进行升级，需要的朋友欢迎咨询，下位机是源码，上位机为应用程序，而且写了很多文档，基本是傻瓜式教学，保证能学会 本人用的是周立功usbcan-e-u，canalys_2都可以，其余的can设备也都可以做 <link href="/image.php?url=https://csdnimg.cn/release/download_crawler_static/css/base.min.css" rel="stylesheet"/><link
