    I would like to be able to just use the Udoo as a computer. It would be nice to be able to dual boot and compare operating systems. Using the SD card is slow, so putting it on SATA is so much better. I am also experiencing other problems that need to be ironed out, so seeing it working on one operating system helps narrow the problem to software and keeps me from bothering you.

    Having Uboot stored on the sd card doesn`t alter the boot speed , or stop you from dual booting etc , or change anything , and stop you doing anything which you would be able to do if the uboot was stored on the sata drive , in fact it adds things which you would not be able to do if it was stored on the sata.
    HOW TO BOOTS , it reads the first few sectors stored on the sd card which take a few milliseconds and waits 5 seconds for you press a key just in case you have a serial connection , then starts using the sata drive to load the kernel and the rootfs .
    To me it`s easier to dual boot with a sd card on uboot , because how it boots is now controlled by the sd card and all the uboot environment variables are stored on the sd card .

    So if you have 2 sd cards , one can be made to boot from partition 1 and the other partition 2 , so with a simple swop of the sd card to can make to multi-boot .

    This issue was discussed on the IRC channel several months ago (around December IIRC). As others have said, there's a certain kind of NAND that (again, going from memory here) uses SPI interface to store the Uboot data. the pads DO exist for that chip on the bottom of the udoo board, but I don't know if all the supporting circuitry is also there or not. A few folks were supposedly looking into it though. Not sure what ever happened with it though.

    Like Peter said though, there are ways around this - just get a couple cheap 2GB microSD's to do what he suggested... I believe you also have the ability to change the timeout from 5 seconds to something shorter in the uboot environment variables.

    Hi,

    First, thanks a lot for this guide!!
    Second, I am having issues and can't get it working for some reason...
    I have attached a sata hdd and made a dd copy of the mmc partition to /dev/sda2 (so there is an ext3 partition holding all the data from the sdcard of the latest lubuntu on /dev/sda2 and I am expecting it to be on sata 0:1). It works fine when I boot from the sata using my old sdcard (which contains also the full fs). After that, I took an empty card and installed there the uboot. Following your guide, I have set up everything but can't boot from this minimal setup:

    Code:

    You say to copied the mmc to sda2 , so you have set satapart=2 .. ?

    Are you able to mount your SATA partition two after booting from MMC SD card?

    Have you run FSCK on partition two?

    Hi and thanks for reply!
    The partition is ok and I found the problem. For some reason, the partition table was not mbr but gpt - the lubuntu itself can mount gpt without any issue so I was so confused because I was able to mount the partition from lubuntu but not from the uboot which needs it to be mbr.
    After converting it, it boots fine and I am good to go!

    thanks for help guys and remember - MBR :)

    This is simply driving me insane. I've tried several methods of "making" a Samsung EVO 120GB SSD my main drive to include copying files to a single ext3 and ext4 partition on the drive. I've followed the Uboot 2013 directions and everything looks good until I get the following error,

    Code:
    VFS: Cannot open root device "sda1" or unknown-block(0,0)
    [    3.229056] Please append a correct "root=" boot option; here are the available partitions:

    [    3.250314] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
    
    Here is the beginning of my boot process,

    I can flip back to the SD card and everything runs fine, but EVERY FREAKING TIME I switch to the SSD I get this stupid error. I've mounted the drive and see that everything looks fine. It's on sda partition 1. What am I missing?

    Yeah, the booting from sata and the fact that it found AND loads the kernel is what is throwing me off. It's like it forgets that the sata drive is mounted when it tries to mount it. I should add that I've successfully loaded and booted off of a 750GB spinning hard drive using the same set of procedures. It looks like it's something related to my SSD type.
