Handle crashdump

[dkerr64]

The ESP32 does not have a crash callback like ESP8266 but it does have crash dump... a 64KB block of flash into which process data is dumped at time of crash.

The firmware currently detects that a crash dump exists, and allows for erasing it. But does not yet provide any way to view or download the contents of the crash dump.

I am noticing the esp32 crashes a few times per day, I suspect it happens when the push button detects motion.

Is there a way I could capture the crash logs to facilitate debugging?

[dkerr64]

ok, so it is concerning that you are seeing this... mine has been very stable. As you probably can tell from this issue, the ESP32 is saving the crash information (and the web page should note this at the very bottom). But we have not implemented any way to retrieve the saved crash data.

If you are seeing frequent crashes, then that is motivation for us to work on that.

In the meantime, if you can figure out a way to reliably recreate the crash, I can try it here.

Oh... and are you using Sec+ 2.0, 1.0 or dry contact?

Thanks.

I’m using sec+ 2.0

I will keep trying to figure a consistent repro. But right now it’s been running 7+hours without issue. So that’s promising.

Support for retrieving crash log data is added in PR #26

Fixed in v3.0.5
