Hello,
i'am trying to implement an STC Runtime check into an AUTOSAR Stack using your SafeTI Diagnostic Library.
This is my function which calls the API:
void stlDrv_STC_RuntimeTest(void)
{
SL_STC_Config stcSelfTestConfig;
SL_STC_FailInfo failInfoSTC; /* STC Failure inforamtion */
__disable_irq();
/* execute the test */
stcSelfTestConfig.stcClockDiv = 1; /* STC Clock divider = 1 */
stcSelfTestConfig.intervalCount = 1;
stcSelfTestConfig.restartInterval0 = TRUE; /* Start from interval 0 */
stcSelfTestConfig.timeoutCounter = 32760; /* Timeout counter */
/* do lock step test and mark it*/
myFaultInjected = 0x12345678;
/* save the core register set */
_CoreRegisterSetSave_(&myCoreRegisterSet[0]);
/* save the stacks of the banked registers */
_CoreBankRegisterSetSave_(&myCoreRegisterSet[16]);
SL_SelfTest_STC(STC_RUN, TRUE, &stcSelfTestConfig);
/* Reentry after CPU Reset */
myFaultInjected = 0x00000000;
/* switch back to System Mode */
__asm( " cps #0x1F" );
/* restore stack pointers */
_CoreBankRegisterSetRestore_(&myCoreRegisterSet[16]);
SL_SelfTest_Status_STC (&failInfoSTC);
if (ST_FAIL == failInfoSTC.stResult)
{
stlDrvErrorCounter++;
}
else
stlDrvPassCounter++;
/* enable the interrupts again, because they have been disabled by the test */
__enable_irq();
}
During my startup code at the very beginning I mask the myFaultInjected variable and jump back into that function. But it seems that there is something wrong because when I connect an debugger after executing I am standing at the Undefined Instruction Exception. Here is the part of the startupcode:
ldr r0, =myFaultInjected
ldr r1, [r0]
ldr r2, =0x12345678
cmp r1, r2
bne no_stc
ldr r0, =myCoreRegisterSet
bl _CoreRegisterSetRestore_
no_stc: // Standard init
I attached the executable for you. Maybe it helps. 7612.exe.zip
The API call is @ 0xBE5C
Thanks and Regards,
Christopher
