Core 0 panic'ed (Interrupt wdt timeout on CPU0) Error

Postby chandan » Wed Dec 08, 2021 9:01 am

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 
dt = ds.DateTime()                      # get RTC date and time
sleep(1)
fdate = str(dt[2])+ "/"+str(dt[1])+"/"+str(dt[0])
ftime = str(dt[4])+ ":"+str(dt[5]) + ":"+str(dt[6])
steps = 0
sleep_time = 60
force_sleep =0
fname = str(dt[2])+str(dt[1])+str(dt[0])        # format date in dd/mm/yyyy

try:
    pa = open("/sd/countfile{}.txt".format(fname))       #TRY TO OPEN STEPS COUNT FILE TO GET PREVIOUS READINGS OF CURRENT DAY IS DATE NOT CHANGED. 
    step_count = pa.read()
    #print(step_count)
    t = int(step_count)
    #print(t)
except Exception as e:
    #print(e)
    pa = open("/sd/countfile{}.txt".format(fname),'w')       # if file doesn't exists, it create and insert zero as steps to start new count series for new day.
    step_count = 0
    pa.write(str(step_count))
    t = int(step_count)
finally:
    pa.close()                                           # finally closes the open document
steps = t

f = open("/sd/datafile{}.csv".format(fname), "a")       # open csv file store steps with x, y, z axis.
while True:
    a = imu.getAccelData()
    dt = ds.DateTime()
    fdate = str(dt[2])+ "/"+str(dt[1])+"/"+str(dt[0])
    ftime = str(dt[4])+ ":"+str(dt[5]) + ":"+str(dt[6])
    if abs(a[0]-p[0]>0.21):
        p =a
        steps +=1
        data = fdate + "," + ftime +"," + str(a[0]) + "," +str(a[1])+","+str(a[2]) +","+str(steps)
        print(data)
        f.write(data)
        f.write("\n")
        print("On")
        sleep(0.2)
        force_sleep = 0
    else:
        p = a
        print("no activity")
        force_sleep +=1
    if force_sleep ==20:
        force_sleep = 0
        print("stops recording & going into deepsleep")
        break
    sleep(0.5)
f.close()
t = steps
pa = open("/sd/countfile{}.txt".format(fname),'w')
pa.write(str(t))             #store updated total steps count of the day
pa.close()
uos.umount("/sd")
print("turn off")
machine.deepsleep(sleep_time*1000)
Here is the console error message which i am receiving :
