Hi
When programming /NordicSDK/v1.3.1/zephyr/samples/basic/blinky in the cpu_app_ns version, it will not start. It is starting when I compile it as a secure application. The sample is modified to monitor a gpio on my custom board:

#define SLEEP_TIME_MS 100
/* The devicetree node identifier for the "led0" alias. */
#define LED0_NODE DT_ALIAS(led0)

#define PIN DT_GPIO_PIN(LED0_NODE, gpios)
#if DT_PHA_HAS_CELL(LED0_NODE, gpios, flags)
#define FLAGS DT_GPIO_FLAGS(LED0_NODE, gpios)
#endif
#else
/* A build error here means your board isn't set up to blink an LED. */
#error "Unsupported board: led0 devicetree alias is not defined"

void main(void)
{
struct device *dev;
struct device *led_dev;
bool led_is_on = true;
int ret;
dev = device_get_binding(LED0);
if (dev == NULL) {
return;
}
ret = gpio_pin_configure(dev, PIN, GPIO_OUTPUT_ACTIVE | FLAGS);
if (ret < 0) {
return;
}
led_dev = device_get_binding("GPIO_0");
gpio_pin_configure(led_dev, 24, GPIO_OUTPUT);
gpio_pin_set(led_dev, 24, 0);
while (1) {
gpio_pin_set(dev, PIN, (int)led_is_on);
gpio_pin_set(led_dev, 24, (int)led_is_on);
led_is_on = !led_is_on;
k_msleep(SLEEP_TIME_MS);
}
}
I'm using nRF Connect SDK v1.3.1, and build the code with Segger IDE rel.4.52
Any idea why the ns version is not working?
