New firmware release 0.9.3.b2

[Xykon]

OK I modified my boot.py file to avoid the crash...

import machine
import os
import pycom

pycom.heartbeat(False)

uart = machine.UART(0, 115200) # disable these two lines if you don't want serial access
os.dupterm(uart)

if machine.reset_cause() != machine.SOFT_RESET: # needed to avoid losing connection after a soft reboot
    from network import WLAN
    wl = WLAN()
	
    # save the default ssid and auth
    original_ssid = wl.ssid()
    original_auth = wl.auth()

    wl.mode(WLAN.STA)

    try:
        wl.connect('MYWIFI', (WLAN.WPA2, 'MYPWD'), timeout=10000)
    except:
        wl.init(mode=WLAN.AP, ssid=original_ssid, auth=original_auth, channel=6, antenna=WLAN.INT_ANT)

In my previous script I would have seen this is the last lines after boot:

MicroPython d78a5a3 on 2016-11-05; LoPy with ESP32
Type "help()" for more information.
>>>

Now I get these extra messages:

MicroPython d78a5a3 on 2016-11-05; LoPy with ESP32
Type "help()" for more information.

state: 2 -> 3 (0)

add 0

connected with WIFISSID, channel 7

And I have to press enter to get the >>> prompt

I'm guessing this has to do with the new threading implementation... the try: block is opening a new thread which causes the WDT to reset and this is why the boot.py manages to complete without causing the WDT to expire.

Still crashes for me during boot when trying to run in WIFI STA mode and connect to my AP.
