[gentoo-embedded] GNAP and DOM

[gentoo-embedded] GNAP and DOM

[Robin Bonin]

Hi, I'm using gnap tools 1.2 and I am trying to put my working overlay
onto a 32 meg DOM.
Following the instructions here,
http://www.gentoo.org/proj/en/base/embedded/gnap-userguide.xml
I have installed the MBR, created the primary active partition
and then ran gnap overlay.


when I boot, I get Searching for Boor Record from IDE-0..Not Found

when  I run 
dd if=/home/robin/gnap/gnap-tools-1.2/mbr/mbr.bin of=/dev/hdc bs=512 count=1
I get 
0+1 records in
0+1 records out

any other things I need to check?

I have noticed that DOM's do not like dd very much.  I have a feeling that
it has something to do with how it works with back blocks.  I have found the
only reliable way to put files on a DOM is to tar/gzip them up and explode
them on it.  I do not know how you would go about this with the MBR due to
it's special circumstances.

After running dd and trying it a few times, it seems that it has worked?
I now am getting past that not boot record error and not I'm sitting
at a black screen completley blank with the cursor at the top left.

I created both a standard linux partition and ran gnap overlay and
also a fat32 and ran gnap overlay (Documentation didn't say what type
of partition) I'm didn't get any diffrence in the output, so I'm not
sure what is happening.

I have a working iso, is there anyway I can place those files on the
DOM? and get it to boot up that way?

I tried installing gnap on a hard drive, and it works. when I run the
exact same command to install it on the DOM I get the blank screen w/
flashing cursor. Any thoughts other than using partition magick or
something the copy the data from the workign hard drve to the DOM? I
have several variations I need to create that will take some time.

Have you tried using the flash_write utility from mdt?  I think that might
be the way to go.

It's generally considered rude to top post unless your legally blind and

I was unable to get it booting with syslinux 3.08 but it is working fine with 
2.13 on a CF card/Soekris combo. Though I got just a tiny bit further than 
your black screen, so my problem might be completely unrelated to yours:-)

I got the same symptoms on a CF card for Soekris 4801. Reverting to an
older version of syslinux did also work for me and everything was ok
afterwards.

I must admin I did not test DOMs (wish I had one), I assumed they would
work like a hard drive would... So there may be something wrong in the
commands used by the gnap_overlay script. Like others said, you can try
downgrading syslinux to 2.13, because my CF tests failed (while my HD
tests were still working) until I did that. If you manage to get it
working, please let us know how you did it !

What version did you use?

what exactly does syslinux do? anything I can do manually

	The version I use is SYSLINUX 1.76 2002-08-27 

	Syslinux is a bootloader like LILO or GRUB. It's purpose is to boot the
system, find the linux kernel and launch it. It's a light and
specifically designed for FAT file systems. When you execute 
	syslinux /dev/hdx
	the device is prepared to launch syslinux at boot time. If you want to
do it manually you have to execute that command. Remember that syslinux
uses the file syslinux.cfg (at the root of the msdos partition) as a
boot time configuration.

	Sorry, I don't know more about it and I never quite diagnosed the issue
with it and my soekris. But I had the same issue with LEAF Bering. 
	Alternatively, you can try it's "-s" option.
