HDMI is not connected

Former Member

Hi everyone! 

 

I have a PicoZed Development Kit and when I connect the HDMI cable the DS1 is not switch on. Other LEDs are switch good.

 

The leds that are on are:

DS8 (power) - red;

DS7 - blue;

D3 (SOM) - green;

D4 (SOM) is switch off, so Zynq PL is configured.

 

I'm connecting a monitor (VGA) through HDMI-VGA adapter. 

 

What could be the problem?

    Initially, you were able to power up and power the SOM:

    DS8 (power) - red;
    DS7 - blue;
    D3 (SOM) - green;
    D4 (SOM) is switch off, so Zynq PL is configured.

     

    But now, you don't even see D3 (SOM) light up, indicating that it's not powering up successfully.

     

    Is that correct?

     

    P8 position should not matter. Are you saying that when Vadj is set for 3.3V the system powers up? (D3 SOM illuminates?)

     

    Thanks for clarifying. I want to make sure we debug first things first.
