Downloading of *.elf built on an inhouse build server goes via S32 Design Studio. After flashing the device is powered off and on again, then:</P><OL><LI>the LED is green but not at full brightness</LI><LI>after some random time 1s, 10s, or even longer the LED starts blinking</LI></OL><P>When we compile and run an example that comes with the S32 DS there is no such random time. ISR controlled LED blinking always starts right away.</P><P>Is there anything that can be done to avoid this random startup time?</P><P>Thx and best regards,<BR />Markus</P> Tue, 30 Aug 2022 15:26:51 GMT https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/DEVKIT-MPC5744P-random-startup-time-of-LED-blinking-test/m-p/1514029#M7642 mweiss 2022-08-30T15:26:51Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/DEVKIT-MPC5744P-random-startup-time-of-LED-blinking-test/m-p/1535505#M7732 <P>Actually the board sometimes issued an error message which I can't remember.
