pytrack: loses gps fix then crashes about pycom-libraries HOT 9 CLOSED

Have you tried the new PyTrack firmware (0.0.4)? Sounds like it could help https://forum.pycom.io/topic/1497/new-pytrack-and-pysense-firmware-release-0-0-4

from pycom-libraries.

I didn't get the new on the forum. I'll install and try it asap and I'll let you know!

from pycom-libraries.

Just tested, it keeps crashing:

the first exception is this:

Guru Meditation Error of type LoadProhibited occurred on core  0. Exception was unhandled.

then it keeps trowing exception and the backtrace keeps getting bigger:

this is after some throwing

Not sure if it help but can't hurt to update the firmware on the WiPy as well, version 1.7.6b1 is available
https://forum.pycom.io/topic/1457/new-firmware-release-1-7-6-b1

from pycom-libraries.

just installed new firmware, is there a way to copy paste the repl full output?

pytrack is now more stable. before 1.7.6b1 it started getting no coords, then crashed after 100-120 cycles.
now it has run for for 1000 cycles more or less, however, after the first 100, it started alternating good reading with none.

I changed a bit the script:

while True:
    print("i: {} loc: {} memfree: {}".format(i, l76.coordinates(), gc.mem_free()/1000))
    i += 1

After starting, the memfree is 45.

output at the end:

i: 1010 loc: (40.80619, 14.33766) memfree: 3.68
i: 1011 loc: (None, None) memfree: 4.4
i: 1012 loc: (None, None) memfree: 4.64
i: 1013 loc: (None, None) memfree: 4.48

i: 1016 loc: (None, None) memfree: 4.512
i: 1017 loc: (None, None) memfree: 4.384

Looking into this now! Will report back with what I find! Thanks :)

from pycom-libraries.

Hey @ozeta, could you please try this GPS file (https://github.com/pycom/pycom-libraries/blob/develop/pytrack/lib/L76GNSS.py)? I tracked the memory leak down to the alarm function in the GPS lib.

I'm now taking a look at the C lib for the alarm and trying to work out why the alarm objects aren't being released from the heap.

Please let me know if this works for you!

Thanks!

Alex

from pycom-libraries.

it works really good!

772 (40.80623, 14.33749). memfree: 4.5504
773 (40.80623, 14.33749). memfree: 4.5120
774 (40.80623, 14.33749). memfree: 4.6112
775 (40.80623, 14.33749). memfree: 4.5184

thanks!

Great! I'll merge this into the master and close this issue :)
