Hello,
In my TC399 Triboard project, I have a reset caused by SMU as confirmed by RSTSTAT.SMU = 1 and further confirmed by avoiding the reset if I set RSTCON.SMU = 0.
I have SMU alarms showing in AG0, AG1, AG6, AG7 but I'm not interested in the actual cause right now.
What I don't understand is that all the SMU alarm actions are disabled for groups 0 to 7 (SMU_AGCFx = 0) so, as far I know, that means the SMU cannot/should not request a reset.
Does anybody know how SMU can generate reset request by means other than the configuration registers?
Thank you very much.

Hello,
You could check the Alarm debug(AD) register after the SMU reset, if it indicates any alarms which could be the reason for reset(if anything missed)
