      Oh this is a very welcome early bug fix release.

      I was trying some periodic Alarm code which was crashing with a Guru Meditation error at about every 142 events on the previous beta. Happy to report that's now running well into the thousands and still ticking away nicely.

      This even before I even had a proper chance to report it! Amazing :-)

              As a hint for everyone who is building the image her- or himself:
              Please update the pycom-esp-idf too. Otherwise the build will not run.

                OK first let me say the new release is a massive improvement, before this same code would crash after only 140 or so Alarm events. However it's still crashing without fail in the 2500-3000 range.

                Note I may well be doing something wrong as I just started with MicroPython this Xmas!

                First the crash:

Rebooting...

                and my code (shortened version I'm using for testing)

                from machine import Pin
from machine import Timer
import micropython 
micropython.alloc_emergency_exception_buf(100)

class LTC4150(object):
    ah_quanta = 0.17067759
    
    def __init__(self):
        self.p_in = Pin('P15', mode=Pin.IN, pull=None)
        self.p_in.callback(Pin.IRQ_FALLING, self.__pin_handler) 
        self.chrono = Timer.Chrono()
        self.chrono.start()
        self.count = 0
        self.time = 0 
        self.lastTime = 0 
        
    def __pin_handler(self, arg):
        self.count = self.count + 1



def periodic_handler(alarm):
    mA = cc.count* cc.ah_quanta
    seconds = cc.chrono.read()
    print("Consumed %.2f" % mA ) 
    print ("Elapsed %d s " % seconds)
    print("Hourly average %.2f mAh" % ((3600*mA)/seconds))


cc = LTC4150()

alarm = Timer.Alarm(periodic_handler, 1, periodic=True)

                If I increase the period say to 10s it still crashes just takes 10x as long, so I think it's more to do with the number of events

                Thanks for the help

                  @jmarcelino thanks for the report, we are investigating why those crashes are occurring. We'll let you know once we discover the root cause.

                    Do we have to call the finalizer explicitly, or is it automatic?

                      Wonderful update I gotta admit. Fixed a lot of memory problems! One problem that has been fixed and I haven't see anybody reporting was that you could run your code 2 times and then it would crash on the 3rd try. It is now fixed and I can upload my code as many time as I want to! Fantastic.

                      Cheers,
                      M.

                            @daniel Thanks for that and the prompt reply.

                            Keep up the good work! The memory issues have been frustrating, because as @mohpor says, something would work some times and not others.

                            I'm still having some issues in that respect, which is why the question about the finalizer. I've still to clarify the details, then I'll report it to you.

                            Cheers,
                            Brian

                                            I think the latest firmware for Linux is borked :) It's my first hands-on with the wipy2 and the upater failed. Digging around I noticed there are no firmware files in the tgz.

                                            There is no firmware directory as per the previous v 0.9.7.. version. I used this link https://software.pycom.io/findupgrade?product=pycom-firmware-updater&type=all&platform=unix&redirect=true
