SOB has a uefi bios, and would not boot anything I tried. So I went trolling thru the bios looking for a way to turn that crap off. The only thing I could find was to disable the tcp chip. Bricked it. According to their web site, a $400 jtag programmer and an 80 dollar adapter are needed to rewrite the bios in that event. Questions beyond that on the forum have been ignored. IOW, that board, while seemingly have great specs, has a windows only attitude. UP is otherwise totally unresponsive to users problem.
As far as I'm concerned, I got screwed out of a 100 dollar bill and a week. The last price I saw for a Udoo was in the neighborhood of 150 dollars. I can get a std mobo, with cpu and enough memory for that. So 4 questions now that its shipping: 1. Udoo X86 Ultra, $267.00 on the Udoo site today. Thats not even close to realistic. The dual/quad is $135 but I can't find any other data on it quickly. Ah, its an arm, claims to be an rpi3 performance wise. 2. can any UEFI bios BS be turned off w/o bricking it? 3. Does it have a working spi driver so I don't have to throw away $250 in interfacing hardware and start writing my configs all over again? The spi must be clocked at at least 25 mhz. Alternatively, can it emulate an EPP port at equ of 5 megabytes a second both ways? 4. How big is it? Their site is slow, and has this annoying pop-over asking where you are nearly everytime you switch pages. All the specs are buried in a pdf download which is near impossible to read as they chose a very light color on a white background for the text. That tells me they have something to hide. I did find the size, about an inch bigger than the pi, both ways. All of this is why I'll be watching the rock64 board at $44 fully stuffed, Claims it doesn't have the pi's i/o bottleneck. And that would be huge. Thanks Erik. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
