如何从-ME2获取指令跟踪

嗨，我正在调试.RealICE.PICDEM2 PLUS板：AC244064（PIC16F1789ME2），RJ45和跟踪电缆连接。MPLAB-X 3.61。Windows 10安装了一个小型汇编程序来验证我的问题，包括在下面。（测试程序按预期运行，LED亮起来，我可以打破/犯罪。在实际的ICE的项目配置中，我设置了一个时钟：125 KIPS（如我在缺省的500 kHz上运行）：跟踪和剖析：数据收集选择=“指令跟踪”，（所有其他DEF）AOT）在“Goto主循环”中设置断点，假设我可以看到跟踪中执行到断点的所有指令。但是跟踪是空的。我在跟踪窗口中发现的是“空TraceFielsRes＝SDYReultTyNOx错误0”。与MPLAB X 3.45在MAC和MPLAB X 2.35上在其他Windows 10计算机上的结果相同。（总是启用“使用最新的固件”，所以在切换时需要一些时间来处理真正的冰。）我错过了什么？

    Hi.
I’m debugging with
• Real ICE
• PICDEM2 Plus board
• AC244064 (PIC16F1789-ME2) with both RJ45 and trace cable connected.
• MPLAB-X 3.61
• Windows 10

Crated a small assembler program to verify my problem, included below.
(The test program runs as expected, LED lights up and I can break / single step the program, using Real ICE.)

I have run the Real ICE self test program, no problems reported.

In the project configuration for Real ICE I have set
• Clock: 125 KIPS (as I'm running on default 500kHz)
• Trace and Profiling: Data Collection Selection = “Instruction Trace”, (all else default)
Setting a breakpoint at “goto main-loop” and assuming I can see all instructions executed, up to the breakpoint, in the Trace. But the trace is empty.
All I find in the trace window is “Empty TraceFile res = SD_RESULT_NO_ERROR 0”.

Same result with MPLAB X 3.45 on a Mac and MPLAB X 2.35 on other Windows 10 computer. (Always enabled “Use latest Firmware” so it takes some time to reprogam Real ICE when switching.)

What am I missing?
