[参考译文] DRA821U：无法将 J7200 EVM 与 Blackhawk USB560v2系统跟踪程序调试器(BH-USB-560v2)连接

仅供参考、板载 XDS110调试器没有此连接问题。 EVM 上的 SW3.2处于 ON 位置。 我的定制电路板存在相同的连接问题、因此我想先在 EVM 上进行验证。  

请查看以下主题是否有所帮助：

谢谢。

尊敬的 Praveen：

感谢您分享这些信息、但它们不适用于我的案例。 我的 USB560v2上的两个 LED 都是绿色的、因此前两个线程的情况与我的问题不同。 我还在 Linux 计算机上尝试过、lsusb 正确检测到调试器、但测试连接仍然失败。 下面随附了日志。

好的、您能告诉我们为什么您没有使用板载 XDS110接口吗？

此外、如何将  USB560v2连接到 J7200 EVM？

我们通常使用板载 XDS110接口。 根据您的上述答案、我们可能需要检查并尝试在最后查看我们是否遇到了您提到的相同问题。  

谢谢。

尊敬的 Praveen：

我实际上想调试我没有 XDS110的定制板、但我发现 USB560v2不能与定制板一起使用。 我在 EVM 上试过、发现它也不起作用。 我通过 MIPI 60连接器将 USB560v2连接到 EVM。

我们试用了 Blackhawk XDS5560v2、并成功连接了 TI EVM。 测试连接日志如下所示。 您是否有额外的 XDS560v2可以试用？

The IR/DR scan-path tests used 11.75MHz as the highest frequency.
The IR/DR scan-path tests used 10.38MHz as the final frequency.

-----[Measure the source and frequency of the final JTAG TCLKR input]--------

The frequency of the JTAG TCLKR input is measured as 10.37MHz.

The frequency of the JTAG TCLKR input and TCLKO output signals are similar.
The target system likely uses the TCLKO output from the emulator PLL.

The test for the JTAG IR instruction path-length succeeded.
The JTAG IR instruction path-length is 4 bits.

The test for the JTAG DR bypass path-length succeeded.
The JTAG DR bypass path-length is 1 bits.
