Update U-boot

Hi everybody,

I have an issue to update u-boot on a sabrelite board.

The u-boot version is :

U-Boot 2009.08 (Aug 16 2012 - 10:06:42)

I want to use last release of yocto. I f I well understand, I need a more recent version of u-boot to take into account new kernel with device tree.

I prepare a SD card with jethro image using dd.

zcat boundary-eval-image-nitrogen6x-jethro.sdcard.gz | dd of=/dev/mmcblk0 bs=1M

I update the 'upgradeu' command to take the script 6x_upgrade into account in place of 6q_upgrade. And I copy u-boot.nitrogen6s and 6x_upgrade script to boot partition.

I also define 'uboot_defconfig':

upgradeu=for disk in 0 1 ; do mmc dev ${disk} ;for fs in fat ext2 ; do ${fs}load mmc ${disk}:1 10008000 /6x_upgrade && source 10008000 ; done ; done
uboot_defconfig=nitrogen6s

When I launch command 'upgradeu', I have the following message:

MX6Q SABRELITE U-Boot > run upgradeu

mmc0 is current device

reading /6x_upgrade

1559 bytes read

## Executing script at 10008000

Please set uboot_defconfig to the appropriate value

Loading file "/6x_upgrade" from mmc device 0:1 (xxa1)

Failed to mount ext2 filesystem...

** Bad ext2 partition or disk - mmc 0:1 **

Card did not respond to voltage select!

mmc1(part 0) is current device

MMC: block number 0x1 exceeds max(0x0)

** Can't read from device 1 **

** Unable to use mmc 1:1 for fatload **

** Bad partition 1 **

Can someone explain me how to upgrade u-boot correctly ?
