AM335x,软件debug时出现如下错误提示,请求帮忙提供解决方法

Other Parts Discussed in Thread: AM3358

我应用的AM3358,CCSV5.5,XDS100V2,debug时出现了该错误,

Error connecting to the target:
(Error -1266 @ 0x0)
Device is held in reset. Take the device out of reset, and retry the operation.
(Emulation package 5.1.232.0)

复位电路是按照TI AM335x的开发板的复位电路设计的,应用的触发式的开工接地,上电复位,我也是找不到原因,请教还能检查一下哪里

  • 先确认芯片是否正常上电启动了,再连CCS。

    量一下上电时序正确吗?如果可以的话把板子的启动模式设置成为uart0启动,通过检测串口0的终端信息,有打印出CCCC吗?

    如果上电就有问题,肯定不行的。可以的话把你的电源和复位部分设计post上来。
