I am trying to debug a test project compiled with Linaro v4.9.3. The compilation completes successfully but when I debug the program it never makes it into main().
The source code I am debugging is: (it's one of the the typical templates)
/*
* ======== main.c ========
*/
#include <xdc/std.h>
#include <xdc/runtime/Error.h>
#include <xdc/runtime/System.h>
#include <ti/sysbios/BIOS.h>
#include <ti/sysbios/knl/Task.h>
/*
* ======== taskFxn ========
*/
Void taskFxn(UArg a0, UArg a1)
{
System_printf("enter taskFxn()\n");
Task_sleep(10);
System_printf("exit taskFxn()\n");
System_flush(); /* force SysMin output to console */
}
/*
* ======== main ========
*/
Int main()
{
Task_Handle task;
Error_Block eb;
System_printf("enter main()\n");
Error_init(&eb);
task = Task_create(taskFxn, NULL, &eb);
if (task == NULL) {
System_printf("Task_create() failed!\n");
BIOS_exit(0);
}
BIOS_start(); /* does not return */
return(0);
}
When I debug, it never makes it into main, when I pause the execution is stuck at:
UInt64 Timer_getExpiredCounts64(Timer_Object *obj)
{
ti_catalog_arm_peripherals_timers_TimerRegsM4 *timer;
UInt32 count1, count2;
UInt32 intr1, intr2;
UInt32 wrap;
timer = (ti_catalog_arm_peripherals_timers_TimerRegsM4 *)
Timer_module->device[obj->id].baseAddr;
if (obj->runMode != Timer_RunMode_DYNAMIC) {
count1 = timer->GPTMTAR; <----------------- THIS LINE
wrap = timer->GPTMRIS & 0x1; /* roll-over occurred */
count2 = timer->GPTMTAR;
if ((count1 > count2) && wrap) {
return ((UInt64)(obj->period - count1) + (UInt64)obj->period);
}
else {
return ((UInt64)(obj->period - count1));
}
}
When I use Linaro v4.7.4 compilation and debug works successfully. I am using the Tiva TM4C129x dev board.
Any help would be appreciated in finding out the reason for this.
Thanks
