TC387:SMU: use a software alarm trigger NMI(Non maskable Interrupt)

[oneday]

Dear experts:

SMU test :Configure the software alarm0 to trigger NMI and  set a breakpoint in "void IfxCpu_Trap_nonMaskableInterrupt(uint32 tin)".When trigger software alarm0, MODULE_SMU.AEX.B.NMISTS=1,but can not enter into the "IfxCpu_Trap_nonMaskableInterrupt(uint32 tin)" .Why?

Please see the following pictures to know more detail:

1.Configure the software alarm0 to trigger NMI .

2.trigger software alarm0 to request NMI.

3.can not enter the "void IfxCpu_Trap_nonMaskableInterrupt(uint32 tin)" and stop at this breakpoint

So how can enter the "IfxCpu_Trap_nonMaskableInterrupt(uint32 tin)" when a NMI request is generated?

Looking forward to your reply.

Hello,

Can you check if TRAPDISx.CPUxSMUT is enabled for SMU to generate trap?

Thanks.

The  TRAPDIS0.CPU0SMUT is disabled by default.When I enabled the TRAPDIS0.CPU0SMUT, triggering software alarm0 can enter the NMI handler.

Thanks a lot.
