Brownout reset reason on Muons?

Hello,

I was wondering if this reset reset would be possible to detect on Muons:

RESET_REASON_POWER_BROWNOUT = 50, ///< Brownout reset.

I do not plan to run the device until the battery is gone, but I'd like to detect when, mostly in extreme low temps during winter, the battery was not able to provide power to the device.

Thanks!

It is not possible because the reset reason is lost on brownout on RTL872x.

So a Muon will see a RESET_REASON_POWER_DOWN in this case? Thanks again
