Lopy Lorawan Nano-Gateway crashes



  • Hi All,

    I have here a setup with 1 lopy nano gateway and 5 lopy OTAA nodes connected with the code available on pycom's GitHub. All running the latest firmware v1.11.0.b1.
    After running fine for two/three days the gateway suddenly stopped working. All the nodes were still running fine. I didn't had a console attached so after trying it again with my Mac connected, it crashed already after a day.

    I now have a core dump (it is quite large), but I don't known how to understand it. Here is one of the Guru Meditation Errors:
    Guru Meditation Error of type InstrFetchProhibited occurred on core 0. Exception was unhandled.
    Register dump:
    PC : 0x00000000 PS : 0x00060031 A0 : 0x40082e85 A1 : 0x3ffc09e0

    Can someone help with this?
    Thanks!

    Kind regards,
    Joey
