Unable to forward reset request to SCU after triggering alarm

[User22805]

Alarm configuration:
SMU_AG10CF2 = 1
SMU_AG10CF1 = 1
SMU_AG10CF0 = 0
to forward a reset request to SCU
Triggering Alarm:
Once the error condition is true we are doing the below things
1. Check the state of SSM is in Run or Fault
2. Verifies the alarm is triggered from alarm group dedicated for SW alarm (in our case Alarm 10)
3. Writes the below value in the CMD registers
CMD = 0x06 (SMU_Alarm)
ARG = Alarm 10 (from Alarm Grp 10)
Problem: SW breakpoints hits function to set the alarm status (i.e SW can trigger Alarm) but not able to forward reset request to SCU
Question: Could you please let me know on whether anything further need to be configured?
Also, it would be helpful if you can check that whether am I following correct steps to trigger alarm upon error and forward the reset request to SCU
Thanks for your time in advance

Hello,

Did you configure the SCU_RSTCON (Reset Configuration Register) to define which reset is generated by a reset request trigger from the SMU ?

By writing in the RSTCON.SMU bitfield (7:6), you can choose:

• 0x01: System reset
• 0x10: Application reset

Give it a try, I hope it fixes your issue 🙂
