Power fails on AES-ZU3EGES-1-SK-G  boards

100jwilly

After running I/O carrier board and module for about 4 hours the power to the boards failed.

This has occurred on another board set we using for development. Jumpers on IO carrier boards are in the correct positions and JP1 on SOC module is removed.

Led D10 VIN-HDR is on and led D9 PG-MODULE is off.

Tried cycling the power off and on but will not power up.

Has this been observed on other UltraZed boards? Any way to get this working?

    Hi Josh,

    FWIW this is not easily done. The components are close together and it makes it very difficult to probe with the
    potential of shorting to another component. Each power rail was measured at least 3x.

    These are the measurement on the SOM module.

    L1 :         0.030V

    L2:          0.045V

    L3:          0.005V

    L4:          0.004V

    L5:          0.364V

    L6:          0.004V

    L7:          0.046V

    L8:          0.000V

    I would say this SOM module is dead.
