TMS320F280049: 280049接仿真器出现该问题,供电电源无异常

Part Number: TMS320F280049


-----[Print the reset-command hardware log-file]-----------------------------

This emulator does not create a reset log-file.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-230' (0xffffff1a).
The title is 'SC_ERR_PATH_MEASURE'.

The explanation is:
The measured lengths of the JTAG IR and DR scan-paths are invalid.
This indicates that an error exists in the link-delay or scan-path.

  • 是自己设计制作的板子吗?基于哪款开发板设计的?以及使用的仿真器是哪个型号?

    另外,如果是自己设计的板子第一次连接仿真器出现这种情况,说实话我们这边也很难排查,可能的问题太多了。建议你先自己试试不同的板子,不同的仿真器,甚至不同的仿真器连接线,然后判断一个大概的方向再具体提问会比较好。
