HDMI is not connected

Former Member over 9 years ago

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?

So, I want to share with you my current "progress".

Yesterday it's only DS8 (power) switch on. SOM was dead. But later I changed P8 (that gives 1.8V default) to give 3.3V and it worked (other LEDs switch on, see first post), but HDMI not connected.

Today SOM is not working again.

Probably SD image is reason of this problem but I'm not sure. The fact is that I many times changed and rewriting SD card but now original state of card is restored and it's not working.

New information. When I checked the resistor R250 all the LEDs switch on as it is necessary. But when I turn off and turn on the board only red LED DS8 (power) switch on again. When I checked again this resistor the board is working again as it is necessary, but no HDMI.

Sorry but I'm still waiting for an answer. I saw the related post and didn't saw there the solution to my problem. I followed the instructions of https://wiki.analog.com/resources/tools-software/linux-software/zynq_images (updated Linux image on SD card). It didn't helped me.
