Hi guys, I'm facing a strange problem concerning the boot behaviour with my UDOO quad. I installed Linaro Ubuntu 12.04 on a 2.5 inch harddisk by using dd and I set the root to sda1 in U-Boot as you can see below. Nevertheless UDOO still keeps booting from the SD card. Did I miss something??? The harddisk is working properly - i can mount sda1 without any problems after that I've booted from the SD card ... Any ideas ?

[solved] Re: SATA problem - not booting from harddisk Hi everybody, I found the solution to my problem by playing around with the environment variables in UBOOT. So if you got the same problem as I did you might want to try the following: Don't mess around with setenv root root=/dev/sda1 (or whatever your harddisk device might be) instead try seting setenv mmcroot root=/dev/sda1 rootwait rw In my case that was the solution!!! Now root gets mounted from my SATA disk! Cheers!
Steve, Does this boot without a micro SD card installed? Once I get my disk recognized, I plan on booting from it.
Hi DangerousThing, no, sorry I forgot to mention that ... the SD card is still needed. So you still have the kernel on the SD card but the linux root file systems on the SATA disk which should give you a better performance. I don't know why the 'official' way to enable SATA was not workinging for me. Apparently I am the only one experiencing this problem which is indeed quite curious ...
Thanks. I have a few more questions if you don't mind: What do you really need on the SSD card, or did you not experiment? In other words, can I just have a /boot with the kernel on it and forget the rest? Currently I have a 64 GB micro SSD that will pretty much be doing nothing shortly. I guess i could go back to my 8 gig card. To get my drive recognized I used the ubuntu image at Udoo and the win32 imager, and then expanded the base partition and added a swap partition with gparted, but to do that I had to drag a monitor, mouse, keyboard and such to my bedroom (yes, I have my Udoo in a box on my bed at the moment). I'm planning to run headless, so I was hoping I didn't need to do anything with a windowing system. I strongly suspect that the parted that comes with Udoo's Ubuntu is extremely outdated. I'm hoping that swap works because I did put a 2.2 gig swap partition. Now all I have to do is to figure out how to get wireless networking working without the windowing system (it works fine when I dragged all that stuff back here...). Thanks much for the start. I about to put about 800 GiB of SSD drive on my machine. Have a nice day!
Hi again, I haven't yet tried to remove most of the files from the SDcard because I have only used a 8GB card .... so it is going to stay in UDOO anyway. But I think you're right - the only thing that is needed on the SDcard is the /boot containing the kernel. I think I read that somewhere either in the manual of in the forum. Adding a swap partition should work. I haven't tried it 'cause I'm using my UDOO as a NAS server running the OpenMediaVault distribution (with a custom kernel) and memory consumption has never been higher that 50% so there was no need to add swap space. I'm also running my UDOO headless which makes sense for a NAS server. In case I need to access UDOO I'm connecting via ssh or even sometimes using the USB connection and a terminal emulation, e.g. when I was playing around with the boot parameter of U-Boot13.
I'm running from the disk now. I'd like the swap partition because I want to compile everything from scratch, including the kernel. It's how I've run every Linux system I've ever run. Since I'm using this board purely as an experimental system, I don't think it will matter much. I'm doing the main programming on the Udoo board so that I can transfer what I am doing to my Raspberry Pi later if the project will fit there. Mostly I'm using ssh to log in, but I want a windowing system available to me, I want to run a media panel that will tailor its media based on facial recognition and some basic like/don't like inputs from the user. That's project 1. After I get my 3d printer, I will build a few robots. I'll start with a couple of small wheeled ones, then go for a dog-sized hexapod if I can get the funds. . Otherwise, a larger dog-sized wheeled robot that I can use as an experimental platform to see if I can build something to help my wheelchair bound wife.
Did you have any other issues? This is the part I'm stuck at, but it's still not booting. I used the linaro 12.04 image to get u-boot 2013. flashed it to the micro, same with the sata drive. Used gparted to expand the sata drive to full, adding swap. Hooked it up to the drive. just changing root in setenv, disk showed up in fdisk but wasn't being booted from. Did your method (changing mmcroot), it just hangs at: Code: [ 2.876063] Waiting for root device root=/dev/sda1...
