I saw on product's datasheet that there are a lot of reasons which could cause an SBC reset via RSTB route. That's fine, but I need to know, most generically, if the reset was due to RSTB or POR. How could I do that?
If reset is caused by POR, it is normal power up sequence, MCU will run initialization for SBC.
If reset is caused by low pulse of external RSTB pin, because MCU reset pin is connected to RSTB, so both MCU and SBC would reset. Pls. check below register for external reset of SBC.
