When R&D develop software on FRDM, they may set SWD PINs to ADC or other fuction, if this happened how can re-enable SWD and to debug and download by Jlink continue?
Hi park,
During reset, the SWD pins should be SWD function.
Please try:
1. Press and hold the reset button;
2. Click the debug option in the IDE;
3. Then release the reset button, the IDE will enter debug mode automatically.
Best Regards,
Robin
