uVision 5.36 : '-fdebug-macro' causes slow start of a debug session

frank_

Hi,

When I build my project with compiler option '-fdebug-macro' and flash into board, pressing F4 (start debug session) shows 'waiting' mouse icon and uVision gets inactive for ~15 seconds - as if it was initialising sth in the background. Eventually, uVision shows debug cursor in main () and I can debug my SW.

When I build without '-fdebug-macro', pressing F4 starts uVision debug session immediately.

I tried J-Link and ULink-Pro with the same result.

Why that might be ?
Do you observe similar behaviour ?
