Hi,
I have a custom board for the nRF54L15. I have already implemented LEDs and a button, which work fine.
But I cannot get the PWM peripheral working, and I do not understand why.
When I try to build my Zephyr project, I get a linker error and the build fails.
This is the error I get:
app/libapp.a(hw_init.c.obj): in function `hw_init`:
C:/project.../src/HW/hw_init.c:38: undefined reference to `__device_dts_ord_30'
collect2.exe: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

My use of PWM with LED is like that:
static const struct gpio_dt_spec led_green = GPIO_DT_SPEC_GET(DT_ALIAS(led1), gpios);
static const struct gpio_dt_spec button = GPIO_DT_SPEC_GET(DT_ALIAS(button0), gpios);
static const struct pwm_dt_spec pwm_beep = PWM_DT_SPEC_GET(DT_ALIAS(buzzer));
bool hw_init(void)
{
if (!device_is_ready(led_green.port)) {
printk("LED_GREEN not ready!\n");
return false;
}
gpio_pin_configure_dt(&led_green, GPIO_OUTPUT_INACTIVE);
if (!device_is_ready(pwm_beep.dev)) {
printk("PWM_BEEP not ready!\n");
return false;
}
}
My board is there:
https://github.com/witc/customBoardnRF54l15/tree/main
Aliases are in ropixon_ZG_v5_0_common.dtsi
aliases {
led0 = &led0;
led1 = &led1;
buzzer = &pwm_buzzer;
button0 = &button0;
//watchdog0 = &wdt31;
};
Thank you very much.
