SOM Power Enable (SOMPWR_EN) Implementation: The SOMPWR_EN signal is an active-high input signal that controls the SOM’s internal power sequencing. It must be driven to a logic-high state for the system to initialize; it should never be left floating or grounded.
Leaving this pin floating may result in indeterminate voltage levels, leading to inconsistent power-on behavior or failure to boot. To ensure reliable startup, the carrier board should implement a firm pull-up resistor or be driven by a dedicated power-supervisor IC. Please refer Power Input Sequencing from the SOM Hardware User Guide.
