Hello NXP team,

 

I am using MPC5744P MCU and MOTORGD devkit connected to a PMSM and i am trying to change the switching frequency online using freemaster using the block of "flexPWM frequency update" that i have seen in an example of NXP to control the PWM submodules as shown below but it doesn't work and the motor can't even rotate with the initial switching frequency. can any one help in this problem please.
