I sell devices that include a DN2800MT motherboard.
Several months ago I had a problem regarding the boot. Process was blocked for minutes on the boot screen. My seller told that it was because of a USB stick joined to the device. Sometimes, some USB sticks have got memory controller problem and the motherboard takes a long time to communicate with. Il manage to solve the problem by changing the USB Stick and all was very good (we sold many devices) until now .
We have a little electronic board that communicates with motherboard via ftdi component (USB <-> RS232). Due to an obsolescence of this component, we had to replace it with the new version and the problem appears. Boot process stays locked on EB code for about 3 minutes and then the device starts. But this time is really too long and I have to find a solution!
My BIOS version is MTCDT10N.86A.0166.2013.0427.1030.
I saw on the forum that I am not alone to face with this issue. I hope I can get a very fast solution.
Thanks a lot.
I am sorry you are having this problems but let me help you.
Checking the website I saw there is new BIOS that fixes some USB issues with this NUC. Please try this update and let me know.
Here is it:
Thanks for your answer.
I saw yesterday these new versions (specially V1.69) and thus downloaded V1.70 to my board.
Now problem is sometimes boot is ok, sometimes I encounter the same problem.
I am now testing with USB legacy disable since (if I did not misunderstood) it should desactivate all USB communication during Boot process... Is this a good idea?
