CC3220S无法通过SWD下载程序

Other Parts Discussed in Thread: CC3220S, UNIFLASH, CC3120

CC3220S怎么用SWD下载程序,使用Jlink连接失败,

datasheet中“JTAG and Debug Ports are Locked”啥意思?

  • jtag或者swd,需要改变sop2,sop1,sop0引脚来选择

  • 进入Uniflash 工具后,将CC3220S的默认Production模式修改为Debug模式,就可以通过JTAG进行仿真测试了,

    因为初始模式下默认是Product模式,将JTAG and Debug Ports are Locked

  • 有两个问题:

    仿真器是普通的Jlink还是xds110仿真器?

    Production模式修改为Debug模式怎么操作,有没有截图?

    注:电路板为自己做的,没有下载过程序。

  • 仿真器使用TI官方的XDS110仿真器

    Production模式修改为Debug模式直接用UART连接到Uniflash进行新建一个工程,将其模式修改为Debug即可,参考应用手册SWRU469

  • 你好,我自己画的tm4c1294最小系统板,请问这样的板子可以用SWD下载吗?因为我的板子只引出了SWD接口,是不是序言特定的下载器,软件用ccs吗
