Hi,
I'm currently developing a certain product having limitted power source (about avg. current < 100 uA).
main SoC is nRF52840, and SDK version is nRF5 SDK 17.
There are no problem in normal cases, but sometimes there is a really "weird phenomena".
When the product operates such a high power modules (such as motor, buzzer, .etc),
the program (might be main SoC) is totally stopped.
(I think, this caused when main power source is unstable...)
In this state, GPIO pin level is not changed and just maintaining the last state.
This problem is only resolved by hard-reset (by battery exchangement)
Above all, I want to know about that "it could be possible this phenomena is happening."
Thank you for all your helps...
Best regards,
Daewoong Kim
