做了一块28379的最小系统的板子，jtag可以下载程序，但是一运行就会退出调试，请问是什么原因？

Susan Yang：

您可以看一下 processors.wiki.ti.com/…/Debugging_JTAG_Connectivity_Problems

您好，我看了您发的链接，但是现在的问题是能把程序下载到DSP中，链接中没有描述类似的情况，现在是点运行时调用 InitSysCtrl()函数之后就会直接退出仿真。具体错误是
C28xx_CPU1: Error: (Error -1044 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 8.0.27.9)
C28xx_CPU1: Unable to determine target status after 20 attempts
C28xx_CPU1: Failed to remove the debug state from the target before disconnecting.There may still be breakpoint op-codes embedded in program memory.It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
C28xx_CPU2: Error: (Error -1044 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 8.0.27.9)

点击运行后仿真器断开了 但程序是否跑起来了？
感觉像是把仿真器挂起了可能是程序跑起来复位了或者电源不稳定断开了等原因 硬件不稳定

您现在下载的是您自己的程序？能尝试下载一下TI的例程吗？另外您的外部JTAG connector部分电路是如何设计的？

回复 Susan Yang:

用的TI的例程也是一样的问题

程序跑起来了一瞬间，然后就跑飞了，电源都检查过，没有突变

Susan Yang：

回复 user4737828:

请您看一下TI建议的连接方式，请注意target和header之间的距离

我整块儿板子都没那么大，是否会是内核的问题呢？
