I am using RTX kernel. One of my task is consisting of number of events. After a particular event is served I am clearing it using os_evt_clr(event_no,task). It is working fine till the no of events are less then 10. i.e. 0x0400 if any more event is added and os_evt_clr(event_no,task) is invoked the OS entered into hardfault_handler mentioned in startup.s.
Please suggest me why it is happening does it is related to the task stack??
