Enabling PWM buzzer in STM32MP13X UBoot

[ravichandra_t]

Hi,

We are working on developing a custom board that necessitates the immediate activation of a buzzer with a predefined frequency as soon as the board is powered up. We are exploring the feasibility of utilizing the PWM driver in U-Boot to achieve this functionality.

Can anyone advise if it is possible to configure the U-Boot PWM driver to meet this requirement? Additionally, we are seeking references or guidance regarding the necessary configurations in the U-Boot device tree and source code to accomplish this task effectively.

Hello,

Same issue here.

Did you manage to do this?

Thanks,
