startup problem, no graphical screen

system doesn't start properly I guess, nothing is showing but this message:
"EFI Shell version 2.40 [21793.17]
Current running mode 1.1.2
Device mapping table
blk0... to blk5
Press ESC in 1 seconds to skip startup.nsh, any other key to continue
"

only power cable, hdmi cable and keyboard (working) is plugged to the board.

 

Have you installed an OS? If so, which one? Are you currently trying to install an OS?

 

I haven't installed an OS yet, it's just the very first boot, I expected to see the drives selection as showed in the video tutorial

 

nevermind, I just typed "exit" and accessed to device and boot management

 

To get directly into BIOS without that shell you need to press ESC sooner. Try pressing ESC repeatedly starting immediately when UDOO is powered.

 

pressing ESC didn't work, maybe because I'm using a wireless keyboard.
Anyway, now Udoo is working like a charm

 

Yes, others have reported in forum that wireless keyboards can be so slow to start up that they can't be used to press ESC quickly enough.

 

I don't have a way of testing this myself, but you can set the UDOO logo to display for X number of seconds within the bios. This might provide enough of a delay for wireless keyboards. Maybe someone else can test this and post the results?

 

thanks, I'll try it
