We found a problem. when nrf52832 is working, after the core power supply is sudden short and release, the power supply mode is LDO and the current is about 2mA, we can judge that the core of the chip has stopped and there are peripheralsen-USTelligent Community 13Tue, 28 Jul 2020 14:29:27 GMThttps://devzone.nordicsemi.com/thread/262031?ContentTypeID=1Tue, 28 Jul 2020 14:29:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a604a14d-6983-4bfb-ba01-84771dd0d469Adong<p>except power on reserve，no other way to recover? such as watch dog</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/261931?ContentTypeID=1Tue, 28 Jul 2020 09:57:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:304904ef-3e15-49b5-8f3d-5b4c8b1d8792Turbo J[quote userid="92273" url="~/f/nordic-q-a/64252/systemp-core-voltage-is-short"]when nrf52832 is working, after the core power supply is sudden short and release[/quote] <p>That<em> should</em> trigger POR.</p> <p>The chip will consume the 2mA (or even more with peripherials) until it it fully initalized and running again.
