在usb-dev-gamepad这个例程中,连接的是usbdevice口



使用这个例程中,出现了错误

1、Stellaris ICDI Error     Could not find an Cortex-M device in the JTAG chain! Please check the JTAG cable and the connected devices.

2、uVision    Error:Flash Download failed Target DLL has been cancelled.

这几个错误如何去解决, 

谢谢

  • 注意:

    usbdevice口仅仅是用来传输usb数据的,要想用这个口下载,必须在用ICDI(即板载仿真器)烧写进usbboot的情况下,用LMflash软件才能烧写程序,而不能用CCS直接烧写。要用ccs烧写的话,必须用板载的仿真器的,不能用usbdevice口。
