what am I doing wrong?

of course NitDroid root is unpacked in that partition

The default .item file for NITDroid from archive http://atrey.karlin.mff.cuni.cz/~pal...12.04-1.tar.gz is:

Code:

ITEM_NAME="NITDroid"
ITEM_KERNEL="uImage"
ITEM_DEVICE="${EXT_CARD}p2"
ITEM_FSTYPE="ext4"
ITEM_CMDLINE="snd-soc-rx51.hp_lim=42 snd-soc-tlv320aic3x.hp_dac_lim=6 console=tty1 root=/dev/mmcblk1p2 rw rootdelay=10 init=/init panic=20 debug"
ITEM_REUSEATAGS="1"

So you may want to add lines with ITEM_CMDLINE and ITEM_REUSEATAGS - i guess ITEM_CMDLINE may be your issue as it finds kernel and gets stuck at starting kernel

Thanks very much. The .item file was generated by installing the nitdroid kernel .deb so I assumed it was correct. I also tried with a simple ITEM_CMDLINEthat just sets the root but with the same result.

I will try the .item file you suggested and report back.

unfortunately no change, I have to recreate that partition in ext4 and unpack NitDroid again to rule out any problems in the filesystem

Hi i have the same problem. I'm trying to install nitdroid by this method : http://forum.nitdroid.com/index.php?....msg135#msg135 , but i stuck on Starting Kernel.. and then the phone powers off.

This is my post at nitdroid forum:

Hi all,
I try to install nitdroid, but when i try to boot from sdcard i get the screen and line "Starting kernel" and after ~ 15 seconds the phone powers off. Any ideas why?

Android is on mmcblk1p5 - i've updated boot.scr
Boot.scr and uImage is on mmcblk1p1

what I would try is:
1. place kernel in /boot of Maemo rootfs, name it zImage-2.6.28.NIT.07 and kernel modules in /lib/modules/2.6.28.NIT.07 of Maemo rootfs and check if it boots
2. do the same but in Android rootfs and check if it boots

I know uboot is better, but I remember multiboot required kernel and modules to be in maemo rootfs while the rootfs was on sd/emmc, so I would give it a try (I didn't boot nitdroid with uboot, didn't have time to play with it yet).

I tried that, but I forgot the modules. Now my N900 is over at nokia care for a clock battery change (I was told to wait 2-3 weeks).

Now I just hope I don't get an E7

U-Booters,

in the last few days I have installed Pali's u-boot with bootmenu. No problems booting pr-1.3 kernel or kp50.

I have not been able to boot the latest nemo image, though. I have tried both with 'run sdboot' at u-boot's console, and using the following .item file:

Code:

ITEM_NAME="Nemo"
ITEM_KERNEL="uImage"
ITEM_DEVICE="${EXT_CARD}p3"
ITEM_FSTYPE="vfat"
ITEM_CMDLINE="root=/dev/mmcblk0p1 rootwait ro console=ttyO2,115200n8 console=tty0 omapfb.vram=0:2M,1:2M,2:2M mtdoops.mtddev=2 quiet"
ITEM_REUSEATAGS=1

as suggested previously in this thread.

Both attempts load the kernel, but it panics with

Code:

mmc0: error -110 whilst initializing sd card

and says that root partition cannot be found.

For the record, I am using a SanDisk uSDHC 4Gb, class 4 (I know it will be slow as hell :-( )

Any suggestions to workaround this issue (besides buying another sd card)?

.item files from http://atrey.karlin.mff.cuni.cz/~pal...12.04-1.tar.gz (linked in first post of this thread) suggests (changes in bold):

Code:

ITEM_NAME="Nemo"
ITEM_KERNEL="uImage"
ITEM_DEVICE="${EXT_CARD}p1"
ITEM_FSTYPE="ext4"
ITEM_CMDLINE="root=/dev/mmcblk0p1 rootwait ro console=ttyO2,115200n8 console=tty0 omapfb.vram=0:2M,1:2M,2:2M mtdoops.mtddev=2 quiet"

and no "ITEM_REUSEATAGS=1" line... I haven't tried to boot Nemo yet, so this is just a tip which values you should double check. Are you sure your ITEM_DEVICE is p3, not p1 on memory card? and that it is vfat formatted, not ext4?

Thanks for the tip!

I tried to create another item file with the proposed changes, but the boot failed with 'no uImage found' or something like that.

For the record, the sd card is partitioned as follows:

Code:

   Device Boot Start     End   #cyls    #blocks   Id  System
/dev/mmcblk1p1          0+  57599   57600-   3686399+  83  Linux
/dev/mmcblk1p2      57600   57727     128       8192   82  Linux swap / Solaris
/dev/mmcblk1p3      57728   58239     512      32768    c  W95 FAT32 (LBA)
/dev/mmcblk1p4          0       -       0          0    0  Empty

which is the standard nemo image.
