C28xx: Error connecting to the target: (Error -233 @ 0x0) 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. (Emulation package 9.4.0.00129),如题，翻译结果如下

连接到目标时出错。
(Error -233 @ 0x0)
JTAG的IR和DR扫描路径不能循环位，它们可能被破坏。
扫描JTAG扫描路径的尝试已经失败。
目标的JTAG扫描路径似乎被破坏了
出现卡在零位或卡在零位的故障。
(仿真软件包9.4.0.00129)

怎么解决啊、、、、、

This utility has selected a 100- or 510-class product.This utility will load the adapter 'jioserdesusbv3.dll'.The library build date was 'Jun 25 2021'.The library build time was '11:45:30'.The library package version is '9.4.0.00129'.The library component version is '35.35.0.0'.The controller does not use a programmable FPGA.The controller has a version number of '4' (0x00000004).The controller has an insertion length of '0' (0x00000000).This utility will attempt to reset the controller.This utility has successfully reset the controller.

The scan-path will be reset by toggling the JTAG TRST signal.The controller is the FTDI FT2232 with USB interface.The link from controller to target is direct (without cable).The software is configured for FTDI FT2232 features.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 brokenwith a stuck-at-ones or stuck-at-zero fault.

Green Deng：

有可能是JTAG损坏。有没有试过更换其他jtag测试一下？

可以参考一下这个链接的说明：software-dl.ti.com/…/ccsv7_debugging_jtag_connectivity_issues.html
