Over the past three weeks, I have been searching on how to get an image
installed on an SD card that is not the demo image that came with my
board. I have been able to goto Narcissus and Download an image, install
it on the SD Card and run it in console mode without any problems.
My problem is now I want to use an X11 Image from Narcissus which I have
created one image for each of the X11 Desktop Environments that are
listed. When I follow the same steps from Trey Weaver's Blog on creating
the SD card, each time I boot the SD card in the BB xm device, I get
only console output.
Someplace I have missed a step or two on how to take this image from
Narcissus and enable the HDMI Output to be displayed on the screen. Does
anyone have references on how this can be done. Once I get this part
working successfully, then I need to duplicate the steps some 200 times
for a specific project I am working on.
Well I will research how to do this as I do not have a boot.scr or
uEnv.txt file on the boot partition. In the instructions from Trey
Weaver it does not say anything about doing the boot.scr or uEnv.txt
files. So I will google and make modifications to my instructions.
Thanks for the direction to look at.
As I work through learning this new technology from trials and errors,
how does one locate specific to them variables regarding ones own setup.
I have taken the following information and created my own uEnv.txt file
which is placed on the /media/boot of my host machine.
When I view the console as it is booting, I see the following information:
In: serial
Out: serial
Err: serial

Which my bootm command has address_uimage of 0x80300000 and from the log
it tells me wrong image format. So I presume that my uImage address is
not located at the 0x8030000 location. How can I find this location?

That address is just where u-boot loaded the 'uImage' and then tried
to boot it..
but didn't like it:

What does mkimage -l show for your uImage on the sd card:
voodoo@voodoo-e6400:~$ mkimage -l /media/boot/uImage
Image Name: 3.2.0-x1.1
Created: Mon Jan 9 11:53:39 2012
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 3006544 Bytes = 2936.08 kB = 2.87 MB
Load Address: 80008000
Entry Point: 80008000
I will get the output of the command listed, but wanted to send a
message as to where I am at. After I got the wrong Image format message,
I restarted BB and got to the prompt. I was trying in commands to see
what it would give and found the printenv command. Upon running it, I
saw a variable of loadaddr which was 0x80200000 which I then made this
change in my uEnv.txt file from the original 0x8030000 to 0x8020000 and
tried to boot again.
During this second boot, I got the point og where it had many periods on
the screen and all of a sudden it quit outputting to the serial port and
on the HDMI monitor I only received the Beagleboard graphical image. I
then plugged the sd card back into my host computer and commented out
the mmcroot mmcrootfs optargs mmc_load_uimage mmcargs and loaduimage
lines with a ; I also made a change to the dvimode which now reads
1280x720-16@60. When I boot with this change, I get output on my Monitor
in console mode.
I then tried to enable all of the options that I previously commented
out and the device would only boot to:
adding dns 192.168.1.1
done.
Starting portmap daemon: portmapportmap: fork: No such device.

where it would stop and does not get to the login prompt. I am working
on this new issue.
However, this seems to boot the “2010” and not “2011” version… I also have the same issue with X11 as you are facing. I dont have any good solutions because I am a beginner (and hobbyist) so my learning/testing pace is slower…
To move forward, I’ve discovered Rob’s Ubuntu Demo image at http://elinux.org/BeagleBoardUbuntu#Demo_Image The download, SD card setup, and “install” is very smooth and I would suggest starting there. The only issues I have are some intermittent USB/Ethernet problems…which others seem to have problems with as well from other recent posts.
Hope that helps,
Please post what you find out,
