I uses MPC5744P MCU board.&nbsp; The only change is that we made the initialization of GD3000 occurs once the code is run (once the MCU board is connected to the laptop) not after pressing start. I think this change has no effect. Please help in justifying this strange behavior.</P><P>Best Regards</P><P>Ahmed</P> Fri, 04 Oct 2024 13:48:32 GMT Ahmed_Abd_El-Hafez 2024-10-04T13:48:32Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Why-the-Inverter-Board-DEVKIT-MOTORGD-doesn-t-draw-current/m-p/1966946#M9615 <P>Hello NXP team.</P><P>The Inverter board (DEVKIT-MOTORGD) That I have just bought since only a month has stopped drawing a current.
