check out e-yes twitter. He had a link from someon, I think crevetor with nitdroid loading with u-boot and a special kernel (I do not recall if it was some MeeGo one or something like this)

I have read on this forum and some months ago (not too many) that someone (at least two users) has created a u-boot initrd to boot Nitdroid successfully.
It was not completed detached from the usage of rootfs because Nitdroid still wants to load some firmwares from rootfs after booting process, but it was however a big step forward.
Unfortunately they haven't published their works but if I remember correctly their posts were on BackupMenu thread

ammyt (current NITdroid dev) is also trying to get it to work with u-boot, maybe worth getting in touch and get the brains together :

I will stop posting here for a while.
I am converting the whole multiboot NITDroid system to the new DAS Uboot utility, many advantages.

// Edit
Or, placing kernel on *very*small-ish dedicated ext2 partition on SD card would allow it to work, and won't cause any problems with ext4 /home/? As I understand it, u-boot just need supported filesystem to read kernel image from it, and later, it doesn't care about partition types, if kernel support them already?

I tested and on my n900 with default busybox is no problem with command dd.
But if somebody else has problem, I can change that code.

The Pali's binary as default search on first eMMC partition, but it is easy to change behavior on sources and then recompile a binary which searches on other sources

some info not soo long ago in the other big u-boot thread :
Posted by Rob1n :http://talk.maemo.org/showpost.php?p...&postcount=156
The patches created by Rob1n or Mirakels is not in the last version of the u-boot code as delivered yesterday. I checked the git code for /arch/arm/bootm.c
It might not be needed to allow the copying of the existing ATAGS + the new ones as specified during u-boot, if you want to go for a pure port, as Rob1n used a hybrid Maemo FS + Nitdroid FS. But then extra work needs to be done.
Also the following post in the same thread (by Mirakels) might help to get more insight.
Anyway, it's getting too deep for me, for now, I'll let the big boys play
Thanks already for all the effort

Only thing still is the firmware. I'll probably just copy the firmware files tot hte nitdroid partition. Will test later tonight.
Finally got it all working I can now boot into Maemo, Meego or Nitdroid without needing to reflash or change cards. I've attached the patch to u-boot I'm using - it appends the initrd and command line (if set) to the atags instead of just ignoring them when atagaddr is set.
For Nitdroid, I'm using multiboot as normal, but fooling it into thinking it's already done the reflash, so it just loads Nitdroid straight away. If anyone's interested, I can also post my initramfs and u-boot scripts.

I found the problem with my crapola not working.
fatls mmc 1 was listing down my Music folder off my eMMC. What the actual ****? It might be because of damaged fat32 though.
Moved bootmenu files to ~/MyDocs/Music/ and it worked.
Would probably still be banging rocks together if not for the Gumstix wiki.
On a side note, it doesn't boot last selected entry, which may be undesirable for those who have ext4 /home who want to use this as daily part of booting. EDIT2: fixed that last part. Made a kp49+fmg's SR fixes COMBINED.BIN image. Anybody else want it?
