Beagle board booting issues

Quick info: I can’t get my beagleboard to run using various instructions i have seen online.

Detailed info and background:

I have inherited a Beagleboard C4 with Zippy ethernet combo board (currently not connected) from another project. It comes with a custom rolled OE operating system on a 4GB MMC. In an effort to understand how the beagelboard works, I have attempted to install my own OS on the beagleboard without much success.

Referring to the manual BB_SRM, I attempted to follow the steps in section 12.2 “Out of the Box”. I received no output in the terminal window, (which is configured correctly as 115200 8N1).

Not dwelling to long on that, I moved on to 12.3 “SD Card Configuration”. The link on page 131 of the manual,

led me to

http://code.google.com/p/beagleboard/wiki/BeagleboardRevC3Validation

which led me to

http://www.angstrom-distribution.org/demo/beagleboard/

Using the instructions found on the last link above, i generated a 2 GB MMC with boot partition containing MLO and u-boot.bin, and Angstrom partition with a seemingly standard linux root filesystem. Booting the beagleboard with this MMC, this is the output i receive before it stops (this is also effectively the result with the USER button held down):

Wrong Image Format for bootm command
ERROR: can’t get kernel image
!
OMAP3 beagleboard.org #

I have also tried to use a Ubuntu image with instructions from https://wiki.ubuntu.com/ARM/OmapNetbook and http://elinux.org/BeagleBoardUbuntu#NetInstall_Method, both of which resulted in similar results, namely “Wrong Image Format for bootm command ERROR: can’t get kernel image”

Any help would be most appreciated.

thanks,

just a couple of things...

drop "mmc init" from your boot.scr/uEnv.txt it's already taken care of
your version of u-boot.. (that'll clear that error ^ )

I've seen this error before, what version of "mkimage" do you have?
since there is no version info, queried directly, it's easier if you
tell us the exact specs of your host os..

i’m not sure where i will find the file boot.scr/uEnv.txt. As far as i can tell, my SD/MMC doesn’t contain that/those. Per the instructions (as i understood them) from http://www.angstrom-distribution.org/demo/beagleboard/, my boot partition just had MLO and u-boot.bin. (I have since copied uImage.bin to the boot partition with no apparent change.)

As far as mkimage, i tried mkimage --version and -h, but didn’t see any info. I’m running 32-bit Ubuntu 10.10. I checked synaptic for mkimage and found the following package installed: uboot-mkimage 0.4build1.

I missed the C4 mention, so I bet it's saved in your nand, (printenv
would show the "mmc init"..)

As far as mkimage, i tried mkimage --version and -h, but didn't see any
info. I'm running 32-bit Ubuntu 10.10. I checked synaptic for mkimage and
found the following package installed: uboot-mkimage 0.4build1.

Yeah, the other user was running mint which used that same version
(ubuntu 10.10) for all the generic packages.. Please retry running
mkimage with a different sd card/reader if available and make sure to
run sync/eject on the drive to make sure it's written.. (odly for him
using a different laptop worked just fine..)

Thanks for the info. In the end, i used “nand erase” to erase the nand on the board, and everything started to work. I tested it with the Ubuntu minimal install and the Angstrom validation image, and am now using the net install to install ubuntu 11.04. So far everything seems to be working great.

Thanks again for the help and info,
Sascha
