I have a problem that SRTC is not Enabled at cold start.


I checked the status register. It seems that SRTC has shifted to the Failure state, because it detected some alarms.

LPSR (Status Reg) = 0x00000065

- EAD bit = 1: Security alarm detected

- TR bit = 1: Counter has reached its maximum value

- CTD bit = 1: Clock Tampering Detected.

- TRI bit = 1: Time read is invalidated.


LPGR (General Purpose Reg) = 0x82400000

- SW_ISO = 1: SRTC is isolated from the rest of the SoC.


Is it able to be enabled when SRTC is in a Failure state?


Best Regards,
