UCD3138的JTAG接口电路图哪里有?这样连接,CCS6.1.3用XDS100V3连接的时候反馈出EMU0和EMU1无法监测的错误信息,这两个管脚怎么处理?

The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).An error occurred while hard opening the controller.
—–[An error has occurred and this utility has aborted]——————–
This error is generated by TI's USCIF driver or utilities.
The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.The explanation is:
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.这是反馈信息

Hi确认一下CCS版本的问题,之前好像记得有些版本用起来是有问题的,建议试一下。
