UltraZed EG not booting

xlmnsp

I am having some problems getting my UltraZed EG starter kit to boot. 

I've followed all of the quick start steps and inserted the supplied SD card. The fan is working.

 

After turning on the board, D10 on the carried board lights up and D15 on the carried board stays dark.

 

D4 on the SOM flashes and if the boot mode is set to SD, D3 on the SOM lights up continously. If the boot mode is set to one of the QSPI modes the SOM stays dark after the D4 flash. Except in some cases if I leave the board on for a while, D3 turns on.

 

Nothing shows up on the serial connection.

 

I hope this description helps with identifying the problem. I would greatly appreciate any help.

    Hi there,

    One more thought.  With the POWER removed and the power switch set to OFF, you should also try to take the SOM off and reseat it into the carrier card.

    Ensure all connections are firm and the male and female sides are properly touching/seated.  Use firm and nor excessive pressure along each edge of the SOM that has a connector.

    *Note, when doing this, ensure you follow proper static protection methods, like with all electronics, ESD can cause damage to this board!
