Hi TI,
We have two question when testing illegal address access.
1. We found that when test code execute to "*testPtr1 = 0xff;", SW will jump to Trap, but we want to know why it doesn't go to trap at "*testPtr0 = 0xff;"
2. During debug, the behavior is OK, SW will enter trap function once and leave(SUBS PC, R14, #8 at end of trap). But when running without debug mode, it enters trap function twice. Do you have any idea why behavior is different?
Blew is our test code.
uint32* testPtr0 = (uint32*)0xf3000001;
uint32* testPtr1 = (uint32*)0x3000000;
uint32* testPtr2 = (uint32*)0x73000001;
uint32 testVal0;
uint32 testVal1;
uint32 testVal2;
*testPtr0 = 0xff;
*testPtr1 = 0xff;
*testPtr2 = 0xff;
Thank you!
Zhihua
