How? In orde to use diferent partition on eMMC, is it just matter of modifying:

Code:

ITEM_DEVICE="${EXT_CARD}p1"

...to contain INT_CARD and correct partition number?

This whole ITEM_DEVICE just tells u-boot on which partition to look for bootmenu.src file and bootmenu.img.d directory, yep? Or is it important for something else, too?

Bootmeny entry for other system on SD card:

ITEM_NAME="My name"
ITEM_KERNEL="uImage"
ITEM_INITRD="uInitrd"
ITEM_DEVICE="${EXT_CARD}p1"
ITEM_FSTYPE="ext4"
ITEM_CMDLINE="kernel cmdline"
This means that you have SD card with first partition ext4. On that partition is kernel image with name uImage and initrd/initramfs file with name uInitrd (both generated by mkimage, see below

If I want to have entry for booting uImage of certain name from SD card, as kernel for Maemo (no matter what kernel I actually put there, under that filename), do I still need to use those ITEM_INITRD and ITEM_CMDLINE, just because I'm using SD card? or is it required only for non-Maemo systems?

If yes, what is diferent on non-Maemo systems, that they need it? May it be, that in case of Maemo, ITEM_OMAPATAG make it read all those things from hardcoded place, and it is why we need to specify them manually, in case of non ITEM_OMAPATAG=1?
