求助 dsp28016 ccs与目标板连接不上

 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 XDS510LC 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,TMS为3.28V。
 我查了硬件没发现什么问题
请高手们指点是什么原因?

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/-1137Error during: Register, Execution, It appears that the target is being held in reset.  This may bedue to Wait-In-Reset (WIR) configuration set by the EMU0=0and EMU1=1 pin settings.  If this is the case, DISCONNECTall CONNECTED devices including icepick and then selectRETRY to clear the WIR configuration.If this is a multi-core system, the master CPU may not bereleasing the DSP/MCU from reset.  Please check yourconfiguration in CC_setup and/or your GEL file to ensure thatnothing is blocking the DSP/MCU from being released from resetI/O Port = 510Board Name: F2808 XDS510USB EmulatorCpu Name: cpu_0Abort:                Close Code Composer Studio.Retry:                Try to connect to the target again.Cancel:                Remain disconnected from the targetDiagnostic:        Run diagnostic utility.

请确认EMU0和1都上拉,TRST下拉,时钟10M。

另外也可以找一块别人能运行的板子试一下你的仿真器和软件系统是否正常。

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:

回复 Lisa:

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。
