I am just using deep sleep function so that my board goes into fixed amount of sleep time and wake up to execute the main program again. When i run my code, the program runs completely fine, and at last board goes into deep sleep mode for 1 minute. and after 1 minutes, board gets in its Core 0 Panic'ed state and unable to run the program.
I am using esp32 pico based (M5atom matrix board). The micropython firmware version is v1.14 and i have tried v1.17 also.

Code: Select all

from machine import Pin, I2C, SoftI2C, SDCard
from time import sleep
import DS3231
import uos
from mpu6886 import MPU6886
import machine

i2c1 = SoftI2C(scl=Pin(21), sda= Pin(25))
sd = SDCard(slot =2, sck = Pin(23), mosi = Pin(19), miso = Pin(33), freq = 10000000)    # initialised SPI communication with sd card 
uos.mount(sd, "/sd")        # mount sd card to view, read and write in files, directories
# Values you can use to initialize the accelerometer. AFS_16G, means +-8G sensitivity, and so on
# Larger scale means less precision
AFS_2G = const(0x00)
AFS_4G = const(0x01)
AFS_8G = const(0x02)
AFS_16G = const(0x03)

# Values you can use to initialize the gyroscope. GFS_2000DPS means 2000 degrees per second sensitivity, and so on
# Larger scale means less precision
GFS_250DPS = const(0x00)
GFS_500DPS = const(0x01)
GFS_1000DPS = const(0x02)
GFS_2000DPS = const(0x03)

imu = MPU6886(i2c1, GFS_500DPS, AFS_4G)

i2c = I2C(0, scl = Pin(26), sda = Pin(32), freq= 400000)        # Initialised I2C communication to RTC module 

ds = DS3231.DS3231(i2c)                         # attached rtc module as ds object


p = imu.getAccelData()                  # get accelerator datas of x, y, & z axis

    step_count = 0
    pa.write(str(step_count))
    t = int(step_count)
finally:
    pa.close()                                           # finally closes the open document
steps = t

Here is the console error message which i am receiving :
