Other Parts Discussed in Thread: DRV8301, MOTORWARE
motorware 的例程Lab01b ,launchpad XL TMS320F2802x 接usb连电脑仿真模式,程序中的两个使能位直接在头文件中改成使能了,程序可以运行(控制DRV8301接无刷电机,电机能转),程序烧写过后,拔出USB,重新上电,程序不运行。
请问这是什么原因,启动三个拨码开关都是接on,应该是flash启动

你好,你的程序是烧写到flash中的吗?例程本身是烧写ram的,断电丢失,要修改为flash运行的
cmd文件如下:BEGIN指向flash,codestart 指向 BEGIN。应该是flash启动,拨码开关也拨到高电平,指向flash启动。为什么不接仿真器 上电不运行?

你好,看一下这个帖子,里面介绍得很详细如何将lab更改为flash boot。因为这是个大工程,所以需要更改的地方挺多的,不只是更改cmd和预定义。
