0.9.3b2 Watchdog error after machine.idle() loop in boot.py

[chrol]

Hi,

I had a wifi setup in boot.py that worked with previous firmware but the machine.idle() loop has to be commented out or I get a watchdog error guru meditation now - which is not obvious and needs to be looked at:

import os
from machine import UART
uart = UART(0, 115200)
os.dupterm(uart)

from network import WLAN
import machine
wlan =WLAN()
if machine.reset_cause() != machine.SOFT_RESET:
    wlan.init(mode=WLAN.STA)
if not wlan.isconnected():
    wlan.connect(ssid="xxxxx", auth=(WLAN.WPA2, 'yyyyy'), timeout=5000)
    while not wlan.isconnected():
        machine.idle()

print("Boot complete!")

I can confirm that this fix is no long necessary with pycom's watchdog fixes in 0.9.4.b1.

I was having the same issue and had posted it on this thread: https://forum.pycom.io/topic/237/wipy-crashes-now-after-update-to-wipy_0-9-3-b2-bin/2

However, it seems like the issue occurs some time after my machine.idle, because I see the print statement. Do you see your "Boot complete!" statement?

Thanks,
Chris

I had the same issue and solved it with a time.sleep_ms(50) in the while loop.

I've been having the same issue. See here for my new boot.py file.
