nrf9160 LED zephyr API does not work

Question

I noticed in Zephyr OS there is an API LED: 
 led_on(dev_io, RED ); <-- does not work gpio_pin_set(dev_io, RED, 1); <-- works well 
 
 what can be the reason ? 
 
 can you show a working example with " led_on " ?

Check out the sample <ncs location>zephyr/samples/drivers/led_pwm, it used the led_on() function. 
 I tested it with the nRF9160 DK and NCS v1.8.0 and it (almost) worked. 
 Initially when I built the sample with the board nrf9160dk_nrf9160_ns I got the error "spm/libspmsecureentries.a.. No such file or directory" , but after changing the name to led_pwm2 ( samples/drivers/led_pwm2 ), it built fine. I will investigate this bug. 
 I flashed the sample and I saw that LED1 blinked. 
 Best regards, 
 Simon
