No booting to Nemo.
I had run Nemo with multiboot before, so I thought it would be easier than to try NITDroid, but couldn't make it. Tomorrow will try NITDroid manual install.

Question - uboot+kernel boots before /sbin/preinit runs when booting into Maemo 5, correct?

I tried to add ITEM_USEATAG="1" to nemo bootmenu file and nemo kernel booted :-)

indeed now the Nemo kernel boots but i'm getting a kernel panic due to "cannot open root device "mmcblk1p1" and it gives a list of possible partition options but those are the mtdblock0 to mtdblock5 partitions ??? Not the 3 partitions on the SD card.
So the kernel looks at the wrong device to find the root. Any idea ?
EDIT: Maybe the syntax for the discovered external SD card partitions is different than the syntax for the internal ones or due to newer kernel version the names are different ?
Over to Carsten again ?
Thanks everyone for trying to crack this thing. After the hopefully very close successfull Nemo boot we only have Nitdroid left.
Or maybe (k)Ubuntu and Archlinux, but the followers for those are less in numbers and I guess/hope by then all knowledge and experience will be in the open so it's less painful.

Question, if you boot into the u-boot console, don't boot into any O.S., but kick the watchdogs over enough to keep the system from shutting down, if you wait long enough, will the screen shut-off?
I noticed that from the /sbin/preinit shell, if you leave the N900 in it for a while 5-10 min, never timed it, the screen will shut off. Interacting with the keyboard, however, brings it back on.
I'm just wondering if that's the Maemo 5 kernel, one of the bare minimum of drivers loaded in my /sbin/preinit boot-shell (I haven't tested with the one you have in your git repo), or something lower down in the hardware having a built-in screen shut-off-when-idle feature.

For SD the correct device is mmcblk0p1

just tried it with mmcblk0p1 as well, same issue. the kernel still only shows the mtdblock0 to mtdblock5 partitions and panics.
Am I the only one who has a starting/booting Nemo kernel but non-completing all the way to Nemo itself ?
BTW, it's on the SD card.

Command line (bootargs) for MeeGo/Nemo is :
Code:
root=/dev/mmcblk0p1 rootwait rw console=ttyO2,115200n8 console=tty0 omapfb.vram=0:2M,1:2M,2:2M mtdoops.mtddev=2
I tried to add ITEM_USEATAG="1" to nemo bootmenu file and nemo kernel booted :-)
