    Booting from the SD-card: Uboot stuck at I2C:


      Hi Everyone,


      I'm doing a manual build for the Ultrazed-EV-SOM board and When I try to boot the message queue stops at I2C:

      By absence of the defconfig of the board I used the  Xilinx ZynqMP ZCU102 revA defconfig like I've encountered on the old Avnet forums.

      Has someone an idea how to get past this or what might be wrong?

          It seems odd that it is stopping at that location.  The first thing that comes to my mind is to reseat the SOM on the carrier.  The connectors are rather stiff due to the signal integrity they were designed for.  Make sure to carefully disconnect the SOM.  Then after aligning it, press it back in following the perimeter of the board pressing every 1 inch or so.  Visually look along the edge of the connector and ensure that the top and bottom are mating properly.


          Of course follow all ESD safety when doing this as you will be touching the bare board during this process.
