Errate 2.17.4 says: > Upon enabling the RTC tamper detection feature, a false tamper > detection *can* be reported by the RTC. It turns out that this spurious event is not always generated. If RTC alarm is used and the CPU was previously woken from hibernate by RTC, it *can* happen that the false tamper event is *not* generated. In this case, we will block indefinitely on the mutex. To solve this, add a timeout to the event. Also poll the event instead of using a mutex, as we have already set `PM->SLEEPCFG.bit.SLEEPMODE` at this point. |
