So I am working on a project with MCU expresso and and a jlink and alot of the developers myself included believe the lag time between hitting download and debug is astronomical. Is there a better SWD debugger that might give better performance.
Thanks,
If you are fortunate enough to have one of the J-Link or J-Trace models that supports Segger's Ozone debugger, it is much-much faster in both download and when hit a break-point. I use a Cortex-M J-Trace with ethernet connection debugging RT1176. I build with MCUExpresso, but debug with Ozone.
