F29H859TU-Q1: About the RAM trace function of C2000

Hi Expert,

 

I have question about the communication speed of the C2000 RAM trace function (internal RAM data capture).

 

In internal RAM data trace (capture) tests using third-generation C2000 products, the results were significantly below the expected value (tens of MBPS). We're looking forward to seeing what kind of communication speeds can be achieved using the debug functions (Real-time JTAG, ERAD, DLT) of the new F29x series.

 

Looking at the Debug Probe Performance Comparison page in Resource Explorer, data for the F29x series isn't yet listed, but the maximum value for "Binary (.bin) load to SRAM (kB/s)" for the F280049C is 140 kB/s, or about 1 MBPS. Other processor products are also around 700 kB/s (5.6 MBPS).

Therefore, I think it would be difficult to achieve several tens of MBPS with XDS. What kind of communication speeds are actually possible with the F29?

Also, if you know of any high-speed third-party trace tools, could you please recommend them?

 

Best Regards,
