Ubiboot.config seems to have a problem due to my partition mess. What will happen if I change so: G_EXPORTED_PARTITONS="/dev/mmcblk0" # This exports all partitons of the device #G_EXPORTED_PARTITONS="/dev/mmcblk0p1" # this exports just the Mydocs partiton #G_EXPORTED_PARTITONS="/dev/mmcblk0p2" # this exports just the root (nemo) partition #G_EXPORTED_PARTITONS="/dev/mmcblk0p3" # this exports just the home (root) partiton #G_EXPORTED_PARTITONS="/dev/mmcblk0p4" # this exports just the nemo (home) partition #G_EXPORTED_PARTITONS="/dev/mmcblk0p5" # some people have more than 4 partitions #G_EXPORTED_PARTITONS="/dev/mmcblk0p6" # some people have more than 5 partitions #G_EXPORTED_PARTITONS="/dev/mmcblk0p7" # this is the last supported partition I guess #G_EXPORTED_PARTITONS="" # this turns off partition exporting And then change partitions number due to that in the section stating with: # The first OS is usually Nitdroid. # This section lists the Nitdroid specific switches and kernels G_OS1_NUM=3 G_OS1_AUTOBOOT=0 G_OS1_PARTITION=2 (to 3 for Harmattan and Firefox too.) And the Nemo now 4 to 2 But what about : "It's important that the versions of the kernel, config and cpio are compatible or else you will run into no end of trouble."
