FWIW, I added the /etc/fstab entry provide (for /dev/loop2) but I
still get this at the end (from build/tmp-angstrom_2010_x-eglibc/work/beaglebone-angstrom-linux-gnueabi/cloud9-image-1.0-r0/temp/log.do_rootfs

Are you familiar with makebootfat?

FWIW, there's a new patchset published in OE-Core ML to address memory issues 
of genext2fs...

Interesting... I think I looked at it before, just need time to try to 
integrate it, time permitting.

Yeah, that was just because i wasn't in the 'disk' group in
/etc/groups.  Thank you to the interwebs for digging that one up for
me.

The compile is finishing for me currently, but I still can't get it to
boot, built on debian/unstable.  The MLO I build doesn't seem to get
recognized by my A4 beaglebone.  The ROM code spits C's at me as if
the microSD card wasn't there.  The microSD card is okay though (an 8
gig Kingston class 10 thing), because I can /sbin/dd the online
angstrom cloud9 demo image[1] on it and that boots.

Then you can't build this image.

Simply put: because the tools suck. A this point in time there is no tool (or tools plural) that allows creating 2 partitions (vfat and extX) and concatenating them into a valid image with an MBR. The biggest lack is something like 'genfatfs', mcopy is a step in the right direction but is too limited to work in this scenario.
And genext2fs will likely OOM on a lot of buildmachines.

Correct, it's the gift that keeps on giving :(

Anyway, why are you posting this to the angstrom list? The cloud9 recipe and offending bbclass live in meta-ti.

But this is just to be able to generate a packed image that can be
copied directly to media?  Maybe that should be a different image
type, like the .u-boot images?  Then it would be obvious what's
being done and why.  In my case, I'm more than happy running a script
to copy the appropriate files to my SD card, etc. and I don't care
(nor especially want) a packed image.

Fair enough, I'll try to keep the discussions where they are most relevant.

Just for reference, the directdisk stuff that was in OE-Core did
something like this (create an MBR with a couple of partitions following
it). It was removed as having some minor bugs and being unneeded but the
code might prove an interesting starting point to addressing this
problem. To come back, it would need to be a proper IMAGE_FSTYPES entry.

When I last tried to use that code it created images incompatible with the boot ROM used in TI SoCs :(
