How to use two sw_pwm instances with nrf5340 with Zephyr?

Question

Hi folks,

I've been trying to use the sw_pwm to generate two PWM outputs. I'm using sw_pwm because I want to achieve lower frequencies (1-100Hz) and the hardware PWM API only supports lower frequencies up to 4 HZ.

My issue is when I run both channels, the channel 0 stops working while channel 1 still working as we expect.

This is my overlay file:

&pwm0 {
	status = "disabled";
};

&sw_pwm {
	status = "okay";
	channel-gpios = <&gpio0 30 PWM_POLARITY_NORMAL>, <&gpio0 31 PWM_POLARITY_INVERTED>;
};


/ {
	my_pwm_leds {
		compatible = "pwm-leds";
		pwm_led01: pwm_led_01 {
			pwms = <&sw_pwm 0 PWM_MSEC(200) PWM_POLARITY_NORMAL>;
		};
		pwm_led02: pwm_led_02 {
			pwms = <&sw_pwm 1 PWM_MSEC(100) PWM_POLARITY_INVERTED>;
		};
	};
};

/ {
	aliases {
		pwm-led01 = &pwm_led01;
		pwm-led02 = &pwm_led02;
	};
};

And this is my app code:

#include <zephyr/kernel.h>
#include <zephyr/sys/printk.h>
#include <zephyr/device.h>
#include <zephyr/drivers/pwm.h>

static const struct pwm_dt_spec pwm_led1 = PWM_DT_SPEC_GET(DT_ALIAS(pwm_led01));
static const struct pwm_dt_spec pwm_led2 = PWM_DT_SPEC_GET(DT_ALIAS(pwm_led02));

int main(void)
{
	uint32_t max_period;
	printk("PWM-based blinky\n");
	if (!pwm_is_ready_dt(&pwm_led1)) {
		printk("Error: PWM device %s is not ready\n",
		       pwm_led1.dev->name);
		return 0;
	}

	if (!pwm_is_ready_dt(&pwm_led2)) {
		printk("Error: PWM device %s is not ready\n",
		       pwm_led2.dev->name);
		return 0;
	}

	max_period = PWM_HZ(10U);

	pwm_set_dt(&pwm_led1, max_period, max_period / 2U);
	pwm_set_dt(&pwm_led2, max_period, max_period / 2U);
	return 0;
}

Does anyone previously integrated multiple sw_pwm instances? O what other options should I follow to achieve lower frequencies for the pwm output (below to 4Hz)?

Regards!
