Hi DYenEmbedded (Community Member)

The User manual that you refer were transposed to our st wiki

https://wiki.st.com/stm32mpu/wiki/Main_Page. It's search engine is quite powerful.

For instance:

https://wiki.st.com/stm32mpu/wiki/PWM_overview#Sysfs_interface

Did you update your DT inside the timer node with the pwm subnode?

pwm {

compatible = "st,stm32-pwm";

#pwm-cells = <3>;

interrupts = <GIC_SPI 119 IRQ_TYPE_EDGE_FALLING>; // Example interrupt configuration

...

};

can you list it onboard ? cat /proc/interrupts ?

Rgds,

Olivier
