I have an issue with a custom board based on nrf9160 sip. So the scenario is that I have a battery with 3V cut-off voltage protection. So if there is not enough solar charging and the battery go does below 3V, the battery stop supplying the board. in this case, even though the battery recover, the device doesn't kick off and I cant see any booting messages unless I removed the battery completely and plug it in again. So when I check PIN 32 nReset pin of nrf9160 is in a lockup state with low. I guess this is the brownout reset mode, right?
I had a search about this issue and came across these issues. I'd like to confirm if these are valid for the nrf9160 or not and to see if there is a way to go out of brownout mode and start again with normal device conditions where it left off.
brownout / watchdog reset on voltage drop
It's designed to require user intervention, like the change of a coin cell battery.
nRF52840 Lockup state with reset low
Theoretically also an incomplete power cycle, e.g. that the rise time of VDD is very slow (>100ms) can cause the chip to not start as expected,
1. So these 2 info are valid for the nrf9160?
2. this 1. comment (required user intervention)seems expelanation of that the device doesnt kick off untill plug the battery out and in. So, if it like this how can I disable brownout.
