求助 dsp28016 ccs与目标板连接不上

有新进展，测硬件后发现EMU0和EMU1被我接反了，现在以调整过来，但也出现新问题，报错如下：

Error connecting to the target:
Error 0x00000024/-1137
Error during: Register, Execution,

It appears that the target is being held in reset.  This may be
due to Wait-In-Reset (WIR) configuration set by the EMU0=0
and EMU1=1 pin settings.  If this is the case, DISCONNECT
all CONNECTED devices including icepick and then select
RETRY to clear the WIR configuration.

If this is a multi-core system, the master CPU may not be
releasing the DSP/MCU from reset.  Please check your
configuration in CC_setup and/or your GEL file to ensure that
nothing is blocking the DSP/MCU from being released from reset


I/O Port = 510

Board Name: F2808 XDS510USB Emulator
Cpu Name: cpu_0

Abort:                Close Code Composer Studio.
Retry:                Try to connect to the target again.
Cancel:                Remain disconnected from the target
Diagnostic:        Run diagnostic utility.

Terry Deng谢谢你的回复

EMU0和1都上拉，TRST下拉，都有 ，插上仿真器后 TCK没有信号，TRST一直为低

仿真器和软件系统是正常，我一连上过板子的

请检查一下复位电路，并量测一下电平是怎样的？

另外，JTAG部分的原理图是否可以发出来检查一下？

dsp的复位是高电平。

电路图如下：

硬件上没看出什么问题，可是你确定XRS是持续高电平吗？请连续量测连接的瞬间，然后展开看看是否有低电平？周期是多少？

xrt确定持续高电平，连续量测连接的瞬间展开有低电压，大概200ms。
