Moderator · February 6, 2026, 6:51am

The G35M, G30M and G36S SBC SOM features three LEDs to monitor system power and the functional state of the Zynq UltraScale+ MPSoC.

Power-Good Indicator: The Red LED serves as the primary power status indicator. It is tied to the final stage of the SOM’s internal power-up sequence and illuminates only when all internal voltage rails have stabilized. This LED provides a visual confirmation that the SOM’s internal power management system is operating correctly and is stable.
PS_ERROR_OUT: A green coloured LED is provided. It is asserted for accidental loss of power, a hardware error, or an exception in the PMU.
PS_ERROR_STATUS: A green coloured LED indicates a secure lockdown state. Alternatively, it can be used by the PMU firmware to indicate system status.

Note: LED colours are different in G36S SBC SOM but its functionalities remain same for G35M, G30M & G36S SBC SOM.
