trace - logic analyzer

ema vac

I'm using keil with STLINK, connected to a GD32F130C8.

I can see, in debug, by means of Watch, variables changing in real time.

Everything works fine.

Now I would like to enable trace, in order to see the evolution of a variable in time domain, thru logic analyzer.

I enabled trace flag on trace tab (setting menu), I set, on trace tab, the processor speed (72MHZ).

The problem is that logic analyzer doesn't show requested float variable, and on the bottom of the screen I read the sentence "Trace: No Synchronization".

The output of SystemCoreClock() function gives 72Mhz.

any hint?

    Search “trace” on this page

    The only mention of trace on that page is saying that you can use the ULINK-pro - which has trace capability.

    It doesn't say that the chip has trace capability.

    In the user manual of gd32 processor I can also read

    Again, for clarification of their documentation, and/or their chip's features & capabilities - you need to contact them.
