    Nicla Sense ME Large Array Crash

    Hi, when uploading the code below, which is using a "large" array, to the Arduino Nicla Sense ME, the following error message comes up:

    ++ MbedOS Error Info ++
    Error Status: 0x80FF0144 Code: 324 Module: 255
    Error Message: Assertion failed: _stack_buffer != NULL
    Location: 0x430B9
    File: ./mbed-os/connectivity/drivers/ble/FEATURE_BLE/TARGET_NORDIC/TARGET_NORDIC_CORDIO/TARGET_NRF5x/NRFCordioHCIDriver.cpp+186
    Error Value: 0x0
    Current Thread: main Id: 0x200051B4 Entry: 0x19E6F StackSize: 0xC00 StackMem: 0x20004590 SP: 0x2000508C

    -- MbedOS Error Info --

    This does not happen if the array is small (e.g. 2 instead of 800), or if the line "BHY2.begin();" is commented out. The example sketches work, but just adding a large array to the code leads to this error.
    The Code:

    #include "Arduino_BHY2.h"
    int all_readings[800];
    void setup() {
    all_readings[0] = 0;
    BHY2.begin(); // if this command is commented out: no error is thrown
    }

    void loop() {
    BHY2.update(); // this line does not impact the error, so commenting it out has no effect on the error.
    }

    Hello maxlo,

    It seems to have something to do with the stack of your software environment. Could you try increasing the stack size in your software environment?

    Hi,

    how would one do that? In the Arduino IDE I found no option to set the stack size.

    Is it some Mbed OS variable that has to be set in the Arduino code? If so, which one is it?

    Hi, is there any missing info we should provide to investigate the problem? This problem has been the main blocker for our development for two weeks now

    Hello Maxlo

     I have just come accross this, so appologies for the late replies.

    We have looked into this, and provided a guide and some resources (pre-compiled libraries etc) to help you on this.

    Please take a look at the details here: https://drive.google.com/drive/folders/1DLr9Z49Or1-Eb-JAZDr6vuLbRhvZii29?usp=sharing

    Please check out the README in the shared folder.

     

     

    Let me know how it pans out.
