otLinkSetChannel leads to hard fault when call from Zephyr-thread

[SoerenBirth]

Hey,

when i call:

otLinkSetChannel(OTInstance, ThreadChannelToUse);

from the very beginning of the programm:

void main(void)
{
    int ret;
    ret = InitLEDs();

    InitTemperatureMeasurement();
    InitUART();
   
    // Setup default configuration
    ProcessReceivedUARTMessage();
    otLinkSetChannel(Instance, ThreadChannelToUse);


    SetLEDOn(DONGLE_RED_MULTI_LED);
    SetLEDOff(DONGLE_BLUE_MULTI_LED);

    return;
}.

everything works, but when this i called from a thread -> it crashed with Hard Fault.

i really need a hint/advise.

regards,

Sören

Edit:

i've found out the the yellow marked line causes the hard fault - it is from "link_api.cpp"

The hard fault may be a consequence of a stack overflow, check out Error Handling-->3.4 Other tips and tools for instructions how to debug this.
