Dropped interrupt for event 64 (TINTLn)

Hi Dongning,

I'm not familiar with INTXERR and I could not it in the main data sheet or the timer64 spru. Where did you find an explanation?

SYS/BIOS does use the lower half of timers 0-7 (one for each core) by default. How did you create timer 8? What other interrupts are you using? Can you insert a snapshot of the Tools->ROV->Hwi and Timers into this thread?

Hi Todd,

Thank you for your prompt reply.

INTXERR is documented in CorePack user guide section 9.2.3.2.

My timer instance is created by the following code:

enum eTIMER {  

TIMER_INST_NUM = 8,  

TIMER_ADDR_BASE = 0x02200000 + 0x00010000*TIMER_INST_NUM,  

 TIMER_64BIT_COUNTER_ADDR = TIMER_ADDR_BASE + 0x10,  

TIMER_FREQUENCY = 1000000 };

void ConfigTimer()

{  

volatile sTimer* timer = (volatile sTimer*) TIMER_ADDR_BASE;  

 timer->tcr = 0;  

timer->cntLo = 0;

timer->cntHi = 0;

timer->prdlo = 0xffffffff;  

 timer->prdhi = 0xffffffff;  

timer->tgcr = 3; // 64-bit GP timer  

timer->rello = 0xffffffff;  

timer->relhi = 0xffffffff;

  timer->tcr = (2 << 6); // (3 << 22) | ;

}

Core0 has teh following HWI usage:

enum eHARDWARE_INT {  

HW_INT_INPUT_MSG             = 4, // PCIE MSI used by master C6678  

HW_INT_INPUT_DATA            = 6, // EDMA  

HW_INT_LOCAL_FRAME_JOB_DONE  = 7, // To interrupt by CpIntc_postSysInt(0, 58). Here our code does not uses I2C 

HW_INT_REMOTE_FRAME_JOB_DONE = 8, // Hyperlink used by master C6678  

HW_INT_CFG_UPDATED           = 8, // PCIE MSI used by slave C6678  

HW_INT_OUTPUT_MSG            = 9, // EDMA  

HW_INT_LOG_MSG               = 10, // EDMA  

HW_INT_HYPLINK_MSG_SENT      = 12, // EDMA  

HW_INT_OUTPUT_DATA           = 15 // EDMA

};

The HWI ROV basic view for core0 is as follows:

 The ROV basic view of the Timer is as follows:

Do I have to use CSL or BIOS to create timer?
