How to determine cause of reset for MIMXRT685

[pcpro1789]

How can the cause of reset for MIMXRT685 be determined in software?  For example, whether it was POR, soft reset, invalid instruction, etc.?

Hi @pcpro1789,

To determine the cause of the last reset, you would have to take a look into the System configuration (SYSCON), specifically the RSTCTL0_SYSRSTSTAT register, as described on section "4.5.3.1 System reset status (RSTCTL0_SYSRSTSTAT)" of the User Manual.
