[讨论] 求助！ccs与目标板连接连接不上

我自己做了一块dsp28016的最小系统，测得电压、时钟信号都是正常的，用的仿真器是spectrum digital 510LC usb

每次连接报错是：
Error connecting to the target:
Error 0x80000200/-1135
Fatal Error during: OCS,
Unrecoverable emulation error
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.

接上仿真器后，测JTAG的TRST一直为低，TCK没有脉冲 TMS为3.28V。


请高手们指点是什么原因？

不要沉贴啊！！！
求助求助！！！

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
