guru meditation error (Lopy firmware version 1.8.0.b1)



  • H!, i've succesfully implemented both nanogateway and node functionality from [https://github.com/franckalbinet/iot-smr3128-ictp/blob/master/labs/lorawan-nano-gateway.md] on my two lopys (firmware 1.8.0.b1), but after some seconds/minutes , the nanogateway crashes and reset, giving a lot of messages related to guru meditation errors like the following. I've seen from other entries that it is not a new issue, but i could not find a fix to it. could anyone help me on this?. thanks
