Can't get CPU PC / LR register value at exception
Configuration in the syscfg file:
m3Hwi.enableException = false;
m3Hwi.excHandlerFunc = "&execHandlerHook";
Use the following function:
volatile uintptr_t *excPC = 0;
volatile uintptr_t *excCaller = 0;
void execHandlerHook(Hwi_ExcContext *ctx)
{
excPC = (uintptr_t*)ctx->pc; // Program counter where exception occurred
excCaller = (uintptr_t*)ctx->lr; // Link Register when exception occurred
while(2);
}
The obtained excPC and excCaller cannot confirm the location where the exception occurred.
Observed values:
Name : *(excPC)
Default:2817851392
Hex:0xA7F50000
Decimal:2817851392
Octal:024775200000
Binary:10100111111101010000000000000000b
Name : excCaller

Hex:0x00000000
Decimal:0
Octal:00
Binary:00000000000000000000000000000000b
Is there any way to locate where the exception occurred?
