File    : SEGGER_SYSVIEW_Config_embOS_Zynq7000.c
Purpose : Sample setup configuration of SystemView with embOS
          on Xilinx Zynq 7010 devices.
Revision: $Rev: 12316 $

Additional information:
  SEGGER_SYSVIEW_TickCnt must be incremented in the SysTick
  handler before any SYSVIEW event is generated.
 
  Example in embOS RTOSInit.c:
 
  void SysTick_Handler(void) {
  #if (OS_PROFILE != 0)
    SEGGER_SYSVIEW_TickCnt++;  // Increment SEGGER_SYSVIEW_TickCnt before calling OS_INT_EnterNestable().
  #endif
    OS_INT_EnterNestable();
    OS_TICK_Handle();
    OS_INT_LeaveNestable();
  }
  
  SEGGER_SYSVIEW_InterruptId has to be set in the IRQ handler
  to identify the active interrupt.
