Just to add to what I have said, I created my SD Card using sakoman instructions from http://www.sakoman.com/category/7-gnome-daily-builds-r12.html.

NB: I ran "sudo ./mksdcard.sh /dev/sdb overo console" for console-image instead of "sudo ./mksdcard.sh /dev/sdb beagleboard gnome".

Daniel,

Things are looking much better now; but I am not really familiarized with the overo# environment since I am a beginner.

I have attached the screen shot of what I got after following what you suggested. Since I don't want to do any mess up, I will leave my Gumstix ON then wait for any suggestion before continuing. 

Any help from anyone please,
Gutembert.

PS. Daniel, in order to compile that script (default-overo-boot) into a boot.scr and place the boot.scr in the boot partition of my SD card, I first made it executable (chmod 775 default-overo-boot) then run "mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n default-overo-boot -d default-overo-boot /media/boot/boot.scr".

Hi Gutembert,

Scott Ellis from JumpNowTek has provided some excellent resources for developing on Gumstix. 

Especially check out the "default overo boot" script available here: https://github.com/scottellis/boot-scripts/blob/master/default-overo-boot

You can either 
  • Enter those commands manually at the u-boot command line, followed by 'saveenv' and 'reset'
  • Compile that script into a boot.scr, place the boot.scr in the boot partition of your SD card, and 
If you restore these default u-boot settings, you should be back in business! (provided your SD card is properly created)

Best of luck

Daniel,

Thank you for the hint; I truly believe that I messed up my boot environment. First of all, my root partition is at /dev/sdc2 and not at /dev/mmcblk0p2, I am not sure if my bootcmd variable is right, my mpurate variable etc.

I have tried to edit using setenv <var> <value> then saveenv; after saveenv, it reboots automatically and indefinitely; when I break into boot, I verify with print command but still my changes haven't been saved.


Here is my boot environment screen shot attached.

Any help is greatly appreciated,
Gutembert.

PS. I am very sorry for asking too much from this Gumstix users group; I am really passionated about Gumstix technology and looking forward to learn although I just get started.

Gutembert,

Your problem (that u-boot repeats indefinitely at boot time) is almost certainly the result of u-boot environment variables that you have saved to NAND. This will not be fixed by recreating your build environment from scratch. You must fix these settings on your gumstix, and save them to NAND.

If you enter the u-boot prompt at boot time, you can use the following commands to investigate/modify your u-boot settings.

'print' - will print the value of every u-boot variable
'print <var>' - will print the value of var ( for example 'print bootcmd' )
'setenv <var> <value>' - will set the value of var to value for the current u-boot session
'saveenv' - will save the current values of every u-boot variable to NAND

Correct u-boot settings will depend strongly on your setup, and it will take effort on your part to determine what these settings should be (it's unlikely anyone on this list knows exactly what settings you need to work with your current setup). See (http://docwiki.gumstix.org/index.php/Uboot) for  more detailed information. 

----
Alternatively, you can create a boot.scr u-boot script to set your u-boot variables. U-boot will execute boot.scr at boot time if it exists (otherwise it will continue with variables loaded from NAND). This approach requires some additional knowledge, however, and I recommend learning by the above approach before creating a boot.scr. (http://wiki.gumstix.org/index.php?title=U-Boot

Creating a boot.scr is particularly useful if you have a Gumstix Overo Tide, which doesn't have any NAND for storing u-boot variable values. 

I highly recommend that you spend some time reading the u-boot documentation, experimenting, and troubleshooting on your own. You will learn a lot this way!

Best of Luck!

Dear Gumstix users,

As J suggested, I'd really love to build my gumstix environment from scratch. But before doing so, I would like to take your advices before buy a new machine (Mac Pro). Will it be okay to have a Mac Pro (Apple) then install Ubuntu 10.04 in it so that I could choose which OS to use during the boot system? I'd really like to use Ubuntu on Mac Pro (Apple) for the overo build environment if possible.

I am looking forward hearing from you,
Gutembert.

Yes J,

I believe that will be the right way! I will buy a new Laptop then install Ubuntu 10.04 and start from scratch. More advices on Laptop's make, Ram, Processor, etc and Ubuntu 10.04 32/64 bits are welcome.

Thanks J,
Gutembert.

Just a quick verification: did you also follow the steps from here: http://gumstix.org/how-to/70-writing-images-to-flash.html or http://wiki.gumstix.org/index.php?title=U-Boot ?

In my case, I did not; is it part of preparing for the SD Card booting process?

Thank you,
Gutembert.

hmmm I did not run into anything like that..but I guess when I did it I started from scratch. I followed pretty much all the steps on the gumstix.net tutorial but checked out a different open.embedded. Did you make mods to the angst-2008-perf-versions before hand? I made changes to the 2010 one I think..for the TI stuff.also why are you changing autoconf? what does that do? The only mod I made was to the local.conf adding the preferred version of 2.6.34..what i would do is check the recipes folder under linux folder and see if there is a linux-omap3-2.6.24 folder. If the checkout went well there should be one.

- On a side note I have not yet been able to boot the 2.6.34 image..its driving me mad! I just deleted my tmp folder and rebuilt it again to see if it will work..I'll let you know how it goes. I might revert back to the 3.0 kernel

I personally find Ubuntu 10.04 to work the smoothest for the overo build environment.

I did not mean to literally buy a new machine, just start from scratch on your efforts :p It is not a machine issue at least from what you have shared it does not sound like it. But me personally would avoid Apple like a plaque.
