File : SEGGER_SYSVIEW_Config_embOS_iMX6.c
Purpose : Sample setup configuration of SystemView with embOS
on NXP i.MX6 devices.
Additional information:
SEGGER_SYSVIEW_TickCnt has to be declared in the module which handles
the system tick and must be incremented in the SysTick_Handler.
SEGGER_SYSVIEW_InterruptId has to be declared in the module which handles
interrupts and must be set to the current interrupt Id as soon as an
interrupt occurred.

#include "SEGGER_SYSVIEW.h"
#include "SEGGER_SYSVIEW_Conf.h"

//
// SEGGER_SYSVIEW_TickCnt has to be defined in the module which
// handles the SysTick and must be incremented in the System Tick
// handler before any SYSVIEW event is generated.
//
// Example in embOS RTOSInit.c:
//
// extern unsigned int SEGGER_SYSVIEW_TickCnt;
// void SysTick_Handler(void) {
// #if (OS_SUPPORT_PROFILE != 0)
// SEGGER_SYSVIEW_TickCnt++; // Increment SEGGER_SYSVIEW_TickCnt before calling OS_INT_EnterNestable().
// #endif
// OS_TICK_Handle();
// }
//
unsigned int SEGGER_SYSVIEW_TickCnt;
//
// SEGGER_SYSVIEW_InterruptId has to be set in the IRQ handler
// to identify the active interrupt.
