Dear Support
I try to use Watchdog on nRF9160 DK.
I found the sample ..\v1.5.1\zephyr\samples\drivers\watchdog
From there I add to my prj.conf
CONFIG_WATCHDOG=y
CONFIG_WDT_LOG_LEVEL_DBG=y
CONFIG_WDT_DISABLE_AT_BOOT=n
And to my source
#include <drivers/watchdog.h>
#define WDT_NODE DT_INST(0, nordic_nrf_watchdog)
void Init(void)
{
int err;
int wdt_channel_id;
const struct device *wdt;
struct wdt_timeout_cfg wdt_config;
wdt = device_get_binding(WDT_DEV_NAME);
if (NULL == wdt)
{
printk("Watchdog setup error\n");
return;
}
/* Reset SoC when watchdog timer expires. */
wdt_config.flags = WDT_FLAG_RESET_SOC;
/* Expire watchdog after 1000 milliseconds. */
wdt_config.window.min = 0U;
wdt_config.window.max = 1000U;
/* Set up watchdog callback. Jump into it when watchdog expired. */
wdt_config.callback = wdt_callback;
wdt_channel_id = wdt_install_timeout(wdt, &wdt_config);
if (wdt_channel_id == -ENOTSUP)
{
/* IWDG driver for STM32 doesn't support callback */
wdt_config.callback = NULL;
wdt_channel_id = wdt_install_timeout(wdt, &wdt_config);
}
if (wdt_channel_id < 0)
{
printk("Watchdog install error\n");
return;
}
err = wdt_setup(wdt, 0);
if (err < 0)
{
printk("Watchdog setup error\n");
return;
}
}
When I build I get from nrfx.wdt.c
#if !(NRFX_CHECK(NRFX_WDT0_ENABLED) || NRFX_CHECK(NRFX_WDT1_ENABLED))
#error "No enabled WDT instances. Check <nrfx_config.h>."
#endif
So something is missing.
Can You tell my what?
