We tried both: attaching HDMI Display on cold boot and cold boot without the
HDMI out. But nothing comes on the display.

We tried on two different HDMI Displays.

We waited for more than 30 minutes, but no message comes.

We have a question. In earlier reply, Paolo told that over kernel is not xenial
kernel.

So is there a way, wherein you can point us to the kernel where the Dragonboard
prebuilt images where built from, so that we can at least get to a point of the
already released prebuilt images, and proceed further.

Awaiting your reply.

Thanks,
Sunny
