Non-aligned Access: ARM Instruction at XXX, Memory Access at YYY

Terje Bohler

Hi.

I get the following error during runtime (after 8 sec run):
"Non-aligned Access: ARM Instruction at 001042F8H, Memory Access at 00000001H
Data Abort: ARM Instruction at 001042F8H, Memory Access at 00000001H"

The failing code contain debug code:

. . .
unsigned int *dbgPinX, *dbgPin11 ...
. . .
if(ch & 0x01)
{
  dbgPin11 = (unsigned int *)(pinsOledData+i);  // for IO
  if (dbgPin11 > (unsigned int *)0x200000)
    dbgX=2;
  else
    dbgX=1;
 dbgPinX = dbgPin11; // THIS LINE CAUSE THE ERROR !!!

 ((pinsOledData+i)->pio)->PIO_SODR = (pinsOledData+i)->mask;
}
. . .


The statement in question is executed lots of times, but 8 sec after each program-start, this statement will fail (every run), with the above mentioned error-message !

If anyone can give me a clue, I'll apreciate that very much.

Regards Terje Bøhler
