Hi, @avinashstarkenn,
I have download our s32k3xx_pwm_edge_aligned_s32ct example onto the S32K344-Q172 board and it works properly. Have you tried to check both pwm outputs, PTA0 and PTA1. Additionally, you can see if the RGBLED0_BLUE is turned on or off using a logic analyzer while the program is running.
Have you tried to run a debug session in S32 Design Studio using the .elf executable file generated with Simulink?
Do you have problems running other examples from our toolbox, such as the basic s32k3xx_dio_s32ct that toggles an LED?
Cheers,
Victor
