 Put the kernel into another partition than the root FS is located.
 Reason: In case the root FS partition is flagged "inconsistent" after a system crash or sudden SD card removal, uBoot won't be able to boot from that partition anymore. But the file system cleanup routines can only be run, once the kernel has been booted. Hence it's safer to put the kernel on a different partition.

 Holding START while switching it on will only work if you have a bootable SD Card with a special MLO bootloader in the left SD slot, as this forces the Pandora to boot from SD.

 Both boot.txt's assume you are booting from the left SD card slot, first partition. You can change "mmcblk0p1" to "mmcblk1p1" if you want to boot from the right slot (but boot.txt must still be on a card on the left slot).

 An alternative approach to using an SD card to increase the space accessible to the system is [[Extend_Utils#OS_Extends | OS Extend]]. This allows the root filesystem to exist on more than one physical device.

		+	Easiest way is to place your new uImage to root of SD (FAT or ext2, ext2 may need a bootloader update) along with a file named 'autoboot.txt', which contains u-boot commands such as:
