hello akshata,

please check below topic for reference to control PWMs,
thanks

Can I make a 25MHz PWM signal?

Hi soo_HyundaiMnSoft, Based on “Tegra X2 (Parker Series SoC) Technical Reference Manual” (Chapter 40), there are 8 PWMs available for the TX2 In the image attached, you can see the frequency ranges supported for each PWM. The maximum rate you can get is 400 kHz for GP_PWM6-GP_PWM7. However those are not exposed at user space level, only the GP_PWM1-GP_PWM4 are available in ‘’‘/sys/class/pwm/’‘’. In this chapter the following is specified: CLK_M (19.2 MHz) or PLLP/4 (102 MHz) are the clock s…
