zephyr wakeup adter sys_poweroff() not working on thingy52

[yopoitio]

I have been trying to implement a way to wake the system up after doing sys_poweroff() but no matter what nothing seems to work. I already tried many examples and none of them work on thingy52. On the other hand, every example worked on nrf52dk (that has the same chip as thingy52). I aleready compared devicetrees and couln't make it work. The objective is to wake up when a shaking movement is detected but now I was just testing with the press of sw0 since the shaking wasn't waking up the system. Below is my current code based on the sample code of nordic for sys_poweroff() (that does work on the nrf52dk but not on thingy52):

#include "bt_service.h"

#include <inttypes.h>

#include <stdio.h>

#include <zephyr/device.h>

#include <zephyr/drivers/gpio.h>

#include <zephyr/kernel.h>

#include <zephyr/pm/device.h>

#include <zephyr/sys/poweroff.h>

#include <zephyr/sys/util.h>

#include <zephyr/kernel.h>

#include <zephyr/logging/log.h>

static const struct gpio_dt_spec sw0 = GPIO_DT_SPEC_GET(DT_ALIAS(sw0), gpios);

LOG_MODULE_REGISTER(STATE_MACHINE, LOG_LEVEL_INF);

int main(void)

{

    int rc;

    const struct device *const cons = DEVICE_DT_GET(DT_CHOSEN(zephyr_console));

    init_bt_service();

    init_advertise();

    k_sleep(K_SECONDS(10));

    if (!device_is_ready(cons)) {

        LOG_INF("%s: device not ready.\n", cons->name);

        return 0;

    }

    LOG_INF("\n%s system off demo\n", CONFIG_BOARD);

    /* configure sw0 as input, interrupt as level active to allow wake-up */

    rc = gpio_pin_configure_dt(&sw0, GPIO_INPUT);

    if (rc < 0) {

        LOG_INF("Could not configure sw0 GPIO (%d)\n", rc);

        return 0;

    }

    rc = gpio_pin_interrupt_configure_dt(&sw0, GPIO_INT_LEVEL_ACTIVE);

    if (rc < 0) {

        LOG_INF("Could not configure sw0 GPIO interrupt (%d)\n", rc);

        return 0;

    }

    LOG_INF("Entering system off; press sw0 to restart\n");

    rc = pm_device_action_run(cons, PM_DEVICE_ACTION_SUSPEND);

    if (rc < 0) {

        LOG_INF("Could not suspend console (%d)\n", rc);

        return 0;

    }

    sys_poweroff();

    return 0;

}

In bt_service.c I only have the functions to initialize bluetooth and the advertisement so I can see when the device is reseted without the console. Also in my proj.conf I have this

CONFIG_PM_DEVICE=y

CONFIG_GPIO=y

CONFIG_CRC=y

CONFIG_POWEROFF=y

CONFIG_LOG=y

# Bluetooth LE

CONFIG_BT=y

CONFIG_BT_PERIPHERAL=y

CONFIG_BT_DEVICE_NAME="Test"

Hello,

I don't see any obvious reasons for why this would not work on the thingy board. Do you have a debugger attached or other ways to confirm that the program actually reaches the sys_poweroff() line? 

Best regards,

Vidar

Yes, I was using a debugger (nrf52dk) attached and if I introduce a small delay before suspending the console I see the message saying "Entering system off; press sw0 to restart". Also, with the app I see that the advertise stops (and since I don't stop the advertise it needs to be from sys_poweroff()). 
I also tried in another thingy52 board and dind't work either, so I assume is not a faulty board.

Thank you

Can you comment these lines to ensure the program will still call sys_poweroff() even if the suspend task failed:

if (rc < 0) {
    LOG_INF("Could not suspend console (%d)\n", rc);
    return 0;
}

Also note that the chip will not enter System OFF mode if the chip is in debug interface mode (also true when you have RTTViewer connected.

I tested removing the lines you suggested. Without the terminal open, the device entered in sys_poweroff() (stopped advertising) but when pressing in the button the system dind't woke up.

Thank you for your time and patience, I already solved the problem. It was a build folder problem (I still don't understand quite well why that caused a problem) but after removing all build configurations and adding one for thingy52 it worked. Again, thank you for your time and help.
