Thanks to the expert assistance of Vaibhav, I can now successfully boot Angstrom on the CraneBoard. If anyone else needs assistance, please don't hesitate to contact me at feinstei@frontier.com.
I am having a problem however... The Angstrom sample load created by Mistral (supplied here: http://www.mistralsolutions.com/pes-downloads/software-downloads/angstrom-download-for-craneboard.html ) seems to default to 640x480 at 60 Hz. Thus, the desktop appears perfectly on my Samsung HDMI television set, but does not appear on my computer monitor (which I don't think sync's that low).
I have tried the following:
1) Plug CraneBoard into 5V power supply while attached via serial port to terminal emulator running on a Windows XP computer (using HyperTerm).
2) When boot code prompts me to stop the booting by hitting any key (and gives me 3 seconds to do so), I halt the booting.
3) I then set the following environment variable "mmcargs" using the setenv program:
#craneboot> setenv mmcargs setenv bootargs console=${console} root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait eth=${ethaddr} ip=dhcp video=omapfb:mode:1024x768@60
Note that I just copied what was already in mmcargs and added the ending: "video=omapfb:mode:1024x768@60" to it
4) I then type "boot" to continue the booting of Angstrom.
The result of this excersize is that:
Angstrom still comes up in 640x480 mode and is still only visible on the HDMI television set. It does not come up in 1024x768 60 Hz mode.....
I'd very much appreciate if someone would tell me (I'm a linux neophyte) what I'm doing wrong! Is typing the "boot" command wrong? Is the syntax of my setenv incorrect? Please help!!!!
