    I Am compiling the xdot-example using mbed CLI and GCC_ARM, and everything compiles correctly and the .bin file is created. After it is copied to the xDot it always gives the same error when injecting the Channel plan:

    ++ MbedOS Error Info ++
    Error Status: 0x8001011F Code: 287 Module: 1
    Error Message: Operator new out of memory

    Location: 0x8004BD5
    Error Value: 0x810
    Current Thread: main Id: 0x20001430 Entry: 0x80051D7 StackSize: 0x800 StackMem: 0x20002050 SP: 0x20002524

    I have tried the following:
    1. override the main stack/thread sizes to 1.5KB and 256B in mbed_app.json
    2. specifying a stack size as suggested in the docs under “Limited System Memory” (just above this link) and creating a thread:

    uint8_t t1_stack[1536];
    Thread main_thread(osPriorityNormal, sizeof(t1_stack), t1_stack);

    Both did not work, and this seems like a problem within the libxDot-mbed5 library.
