I think this is a processor issue. I've got an artemis module and the Weather board and am trying to compile and upload the weather board test program. It compiles and uploads perfectly but when it runs I get :-

MicroMod Weather Carrier Board Test

++ MbedOS Error Info ++
Error Status: 0x80FF0144 Code: 324 Module: 255
Error Message: Assertion failed: status == osOK
Location: 0x24EE9
File: mbed-os/rtos/source/ThisThread.cpp+225
Error Value: 0x0
Current Thread: main Id: 0x100048E0 Entry: 0x25EF1 StackSize: 0x1000 StackMem: 0x10006560 SP: 0x100074BC 
For more info, visit:
-- MbedOS Error Info --
I went to the link but it says the error is unknown. The light on the Artemis board flashes 4 times and then 5 fast flashes and then goes round again. Any ideas?

It's something to do with the test program as below because the sensor programmes on their own work fine.
Code: Select all
 * MicroMod Weather Carrier Board Example
 * This sketch tests all of the weather sensors on the carrier board:
 * atmospheric sensor - BME280, UV sensor - VEML6075, lightning detector - AS3935,
 * soil moisture sensor, wind and rain meters.
 * Priyanka Makin @ SparkX Labs
 * Original Creation Date: August 20, 2020
 * This code is Lemonadeware; if you see me (or any other SparkFun employee) at the
 * local, and you've found our code helpful, please buy us a round!
 * Hardware Connections:
 * Insert MicroMod Processor Board of your choice into the M.2 connector of the SparkFun Weather carrier
 *  Screw into place
 * Connect Weather carrier board to power useing USB-C cable
 * Connect SparkFun Soil Moisture Sensor to Weather carrier using latching terminals
 * Connect both wind and rain meters to Weather carrier using the RJ11 connectors
