Try to use just 2 partitions first, a 40MB FAT32 partition, and a 512MB
ext3 partition.
On the FAT boot partition, you should first copy MLO, u-boot.bin and uImage.
While creating the bootable rootfs partition (disk-1), you can merge the outputs of the
android root and system folders as follows:
# su
# cd /media/disk-1
# rm -Rf *
# cp -a /tool/android-rowboat-2.2/out/target/product/beagleboard/root/* .
# cp -a /tool/android-rowboat-2.2/out/target/product/beagleboard/system/* system/
# chown -R root.root *
# chmod -R 777 data system
You should also check your init.rc file, to ensure that you comment out the
sections relating to mounting the nand partitions.
## mount rootfs rootfs / ro remount
# mount mtd partitions
# Mount /system rw first to give the filesystem a chance to save a checkpoint
## mount yaffs2 mtd@system /system
## mount yaffs2 mtd@system /system ro remount
# We chown/chmod /data again so because mount is run as root + defaults
## mount yaffs2 mtd@userdata /data nosuid nodev
chown system system /data
chmod 0771 /data
Also check your bootargs. The ones that I use are as follows:
# printenv
# setenv defaultdisplay lcd43
# setenv dvimode 480x272MR-16@60
# setenv vram 12M
# setenv mmcargs setenv bootargs console=${console} vram=${vram} omapfb.vram=0:4M omapfb.mode=dvi:${dvimode} omapfb.debug=y omapdss.def_disp=${defaultdisplay} root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait
# saveenv
# boot

Are you able to boot a standard linux omap console image, with the TI DevKit 2.2 kernel
without specifying the init=/init boot args?
This is to try to narrow the issue to being either with the x-load, u-boot, kernel combination
with standard rootfs (which should boot properly first), versus trying to load the android
root file system.
Which version of android are you using?

Could you paste the output of the entire boot process, leading upto the panic?
