The tick hook runs in the context of an ISR. eTaskGetState() does not
end in “FromISR”, so must not be called from the tick hook. Read the
free PDF book and the FAQ “my application does not run, what could be
wrong?” for details on this.
If you invoke the function from the task itself then the task must be in
the running state, not the ready state. The first few lines of the
if( pxTCB == pxCurrentTCB )
/* The task calling this function is querying its own state. */
eReturn = eRunning;
which would indicate eRunning is returns. Try stepping through the
function in the debugger to see why that is not happening.
