How to enable Trace Enable

Asuna

Hi

I'm Asuna. fine!

I am debugging an evaluation board for a microcontroller with a Cortex-M23 core.

"Trace Enable" is disabled in μVision.

Do you know what the cause is?

    That checkbox is disabled if, for example, the connected debug probe does not support trace.

    ULINKpro supports full trace, while ULINK2 supports only SWO trace. There is no trace with CMSIS-DAP (basic).

    Also, if the core has no ITM/SWO, trace is disabled entirely.
