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

100jwilly
100jwilly over 9 years ago

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?

    Hello John and Abushuev,

    We have determined the issue. This issue lies with the amount of current we were supplying onto the SOMs IR part. We have made a change in the BOM that will take place on our next Production SOM build that will eliminate this issue (Will be available mid-July). Seeing as we currently do not have any UltraZeds currently in stock, we are willing to offer our services in getting the reworks done to eliminate this issue on your boards. Please message me if you would like help with this.

    Thank you,

    Josh

    Hi Josh,

    Are you going to post an errata document like for the PicoZeds so that I can do the rework by myself?

    Thanks,
    - Andy
