C28xx:连接到目标时出错:(错误 -233 @ 0x0)JTAG IR 和 DR 扫描路径无法循环位,它们可能已损坏。尝试扫描 JTAG 扫描路径失败。目标的 JTAG 扫描路径似乎因 stuck-at-one 或 stuck-at-zero 错误而中断。(仿真包 9.5.0.00143)
Eirwen:
可以参考Debugging JTAG资料,里面有关于Error -233 @ 0x0的信息:

This utility has selected a 100- or 510-class product.This utility will load the adapter 'jioserdesusbv3.dll'.The library build date was 'Oct 8 2021'.The library build time was '13:26:36'.The library package version is '9.5.0.00143'.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.
—–[Print the reset-command hardware log-file]—————————–
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.

此实用程序已选择 100 类或 510 类产品。此实用程序将加载适配器 'jioserdesusbv3.dll'。库构建日期为“2021 年 10 月 8 日”。库构建时间为 '13:26:36'。库包版本为 '9.5.0.00143'。库组件版本为 '35.35.0.0'。控制器不使用 programmable FPGA。控制器的版本号为“4”(0x00000004)。控制器的插入长度为 '0' (0x00000000)。此实用程序将尝试重置控制器。此实用程序已成功重置控制器。
—–[打印重置命令硬件日志文件]—————————–
通过切换 JTAG TRST 信号,将重置 scan-path。控制器是带有 USB 接口的 FTDI FT2232。从控制器到目标的链接是直接的(无电缆)。该软件针对 FTDI FT2232 功能进行了配置。控制器无法监控 EMU[0] 引脚上的值。控制器无法监控 EMU[1] 引脚上的值。控制器无法控制 output pins上的时序。控制器无法控制 input pins上的时序。scan-path link-delay 已设置为正好 '0' (0x0000)。
硬打开控制器时发生错误。
—–[发生错误,此实用程序已中止]——————–
此错误由 TI 的 USCIF 驱动程序或实用程序生成。
值为 '-233' (0xffffff17)。标题为“SC_ERR_PATH_BROKEN”。
解释是:JTAG IR 和 DR 扫描路径不能循环比特,它们可能被破坏。尝试扫描 JTAG 扫描路径失败。目标的 JTAG 扫描路径似乎因 stuck-at-one 或 stuck-at-zero 错误而中断。
