The firmware reset

Tanuki44

Irregularly, the firmware restarts stopping the printer.
Is there a way to display the origin of the reset?
What are the possibilities apart from perhaps the watchdog if temperature loop is not called every second.
In the case of the temperature loop, does this concern the bed and the hotend?
I mounted a BambuLab A1 compatible hotend, I configured the sensor as follows:
EXT0_TEMPSENSOR_TYPE 14
could this be the origin? It is possible that it was from this moment that the problem appeared...
This also happens when the printer is idle.

When you are connected with a host in console you see the first message on restart which shows reset reason if it was watchdog or power or reset.

What sensor is type 14? Normally if temperature reading works it is ok and would not crash firmware. Only if something hangs infinite time waiting for a response this could trgger a timeout. Reading any analog value would not do it.

I used 100K NTC 3950 for the HotEnd sensor...
It can work for several hours without problem, but also have resets after a few minutes...
I will monitor via the Host and I will say
Thanks

If you see brown out message in host on restart you likely produced a short that happens at some positions only. When voltage then drops from it the board restarts. But there are always a lot of possible reasons especially after modifications.
