Trace buffer is full - using the SWV viewer

Hello,

 

I am using the SWV viewer successfully to output messages from the microcontroller at runtime.

 

This is a nice tool and usually it works fine. 

 

When I run an application for a longer time (e.g. over night) I get this error

2025-08-11 07_24_40-workspace - TST_SGP41_Drivers_SGP41_API_STM32_SGP41.cpp - STM32CubeIDE.png

I did consider the trace buffer as a buffer like outputting to a UART. 

What is happening there?

regards 

Alexander
