MQX for KSDK: lwevent makes errror no_one_to_run

with KDS2.0.0 and KSDK1.1.0. MQX for KSDK configured with PE for FRDMK64F.


In a init-function I create a  event, witch is defined in a global header-file:


     result = _lwevent_create(&sampleStateEvent, 1); //Event auto clear



There is one ISR (every 4096µs) for DMA Complete:



     _mqx_uint result=MQX_OK;


     DMA_CINT = (uint8_t)0x00; //Clear DONE and INT flags

     result = _lwevent_set(&sampleStateEvent, (uint32_t) 2);


     DMA_ERQ =(uint32_t) 0x3; //start DMA Channel 0 and 1 again



In an Task I want to wait for the Event with:


     result = _lwevent_wait_ticks(&sampleStateEvent, (uint32_t) 2, TRUE,0);



For the first pass of the wait command the Task waits till the event is set by the ISR.

Next pass MQX crashs:  ASM_LABEL(no_one_to_run)


Any idea whats my Mistake?
