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 ?
