Hello,
I'm trying to test PWM with a simple example, I've edited spm via adding
KConfig:
config SPM_NRF_PWM0_NS bool "PWM0 is Non-Secure" default y
spm.c
PERIPH("NRF_PWM0", NRF_PWM0_S, CONFIG_SPM_NRF_PWM0_NS),
I'm getting the output at the boot as;

I assume that PWM_0 initialized as Non-Secure successfully.
When I try the code, I don't get any error but I cannot see output on P0.2 either.
#include <nrf9160.h>
#include <zephyr.h>
#include <misc/printk.h>
#include <pwm.h>
void main(void)
{
printk("PWM Application has started!\r\n");
struct device *pwm_dev = device_get_binding(DT_NORDIC_NRF_PWM_0_LABEL);
if (!pwm_dev) {
printk("Cannot find %s!\n", DT_NORDIC_NRF_PWM_0_LABEL);
return;
}
if (pwm_pin_set_usec(pwm_dev, DT_NORDIC_NRF_PWM_0_CH0_PIN, 1000, 500)) {
printk("pwm pin set fails\n");
return;
}
}
