Hi,

With the Keil qVision v5 Logic Analyzer I'm tracing (ST-Link) an single ADC value which is updated every 10 microsecond. Directly after starting the trace I get ''Trace: SW Buffer Overrun''.

Is this a ST-Link limitation or is it a configuration issue?

Thanks.

The ST-LINK is hardly classed as a fast or professional debug solution. Try dropping the sample rate significantly below 100 KHz, or getting a faster pod like a JLink Ultra or ULink Pro
