I'm sure lother devs will modify their solutions to be usable with this U-Boot solution.

Can I have a few requests ?
- Is it possible to auto boot the LAST selected kernel when booting with keyboard closed ? That way it would only be needed to open the keyboard to select a DIFFERENT kernel, and it would allow to boot every time (with keyboard closed) the previously selected non-NAND kernel.
There is problem that saving anything to mmc is not possible yet. But I'd like to implement storing u-boot env to file in MyDocs (and then it is possible to store last boot entry in env variable)

Default timeout is in U-Boot rx51 board code, but can changed by U-Boot variable. I think I will increase default timeout to 30s.

Me too, but without success. NITDroid kernel does not want to boot on my device from U-Boot

so trying to be clever, I tried ITEM_DEVICE=mmc1:2. stil NO GO
all other ITEM_ properties I kept as in the multiboot item file.

Any hint u can give ?

PS. Did I already say I really like booting/playing with kernels this way ?
Syntax is same as for Fanoush bootmenu (I already wrote it ). Here is example config file for booting uImage with uInitrd (with cmdline root=/dev/mmcblk1p2 init=/sbin/init) from second ext3 external mmc partition:

Code:
ITEM_NAME="Test"
ITEM_DEVICE="${EXT_CARD}p2"
ITEM_FSTYPE="ext3"
ITEM_KERNEL"uImage"
ITEM_INITRD="uInitrd"
ITEM_CMDLINE="root=/dev/mmcblk1p2 init=/sbin/init"
Note: seems that U-Boot does not support ext4 (tested: on 1 partition can only list files - not read it, on second see that partition is empty and on third hang up). ext2 is supported (and maybe ext3 too with forward compatibility).
