Compiler/TMS570LS0432: sys.start up Fail

Hi Whong,

You said it failed in crcAtInit_StaticRAM = SL_CRC_Calculate((uint64*)static_ram,1). Is the return CRC value not correct? Or you got an data abort or prefetch abort?

Is &static_ram located in the valid SRAM location?

Do you get the correct CRC value of VIM_RAM, FEE or Flash by calling:

1. crcAtInit_VIMRAM = SL_CRC_Calculate(((uint64 *)0xFFF82000), 256);
2. crcAtInit_FEE = SL_CRC_Calculate(((uint64 *)0xF0200000), 8);

Hello

#define BF_SET(y, x, start, len) \
( (y) = ((y) & (~ (BF_MASK((start), (len))))) | BF_PREP((x), (start), (len)) )

#ifdef __TI_COMPILER_VERSION__
#pragma INTERRUPT ( _excpt_vec_udef_instr, UDEF)
void _excpt_vec_udef_instr()
#endif
#ifdef __IAR_SYSTEMS_ICC__
__irq __arm void _excpt_vec_udef_instr()
#endif
{
while(1);

}

Program execution at while（1）,

crcAtInit_StaticRAM = SL_CRC_Calculate((uint64*)static_ram,1);

this function SL_CRC_Calculate execution some times,then dont know where is running,so I suspend, I found in that postion

Hi whong,

It is the UNDEF exception handler. The MCU enters "undefined mode" when it encounters an invalid instruction.

You can add a breakpoint, then step into the function to find which instruction causes the problem.

Thank you

 I am looking for a problem again.

_coreInitRegisters_();

_coreInitStackPointer_();

and 

SL_Init_R4Registers();

SL_Init_StackPointers();

 I use _coreInitRegisters_(); _coreInitStackPointer_(); function,dont use _coreInitRegisters_();_coreInitStackPointer_();

It reported this when  Icompiling. Is this warning influential?#10247-D null: creating output section ".intvecs" without a SECTIONS specification

Hello 

 I have cancel the “crcAtInit_StaticRAM = SL_CRC_Calculate((uint64*)static_ram,1);”

but _enable_interrupt_();  also  run to the 

#ifdef __IAR_SYSTEMS_ICC__
__irq __arm void _excpt_vec_udef_instr()
#endif
{
while(1);

}

why？

Thank you

Hello Whong,

This UNDEF error is not caused by CRC calculation. It is caused by other variable or function used in your code, but those are not defined.
