https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/freemaster/m-p/2373295#M10769 <P>I built a Simulink model for the S32K344-WB to make an LED toggle on and off every 1 second. I then imported the ELF file into FreeMASTER and monitored waveforms via J-Link. However, after I clicked <STRONG>Go</STRONG>, the signal level on the FreeMASTER oscilloscope stayed as a flat line and did not toggle. When I pressed the physical Reset button on the board, the LED started blinking normally, but the waveform display in FreeMASTER paused. How should I configure the settings to observe waveforms on the FreeMASTER oscilloscope while the MCU runs normally with the LED toggling continuously?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="dream_lostcity_0-1780114306400.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/387358iB3BC40D0C1A39FCB/image-size/medium?v=v2&amp;px=400" role="button" title="dream_lostcity_0-1780114306400.png" alt="dream_lostcity_0-1780114306400.png" /></span></P><P>&nbsp;</P> Sat, 30 May 2026 04:12:40 GMT dream_lostcity 2026-05-30T04:12:40Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/freemaster/m-p/2373295#M10769 <P>I built a Simulink model for the S32K344-WB to make an LED toggle on and off every 1 second.
