[U-Boot] verified boot of beaglebone black

[Srinivasan S]

Hi Simon,

Hi Simon,

As you suggested earlier am using u-boot-2014.07 & Am using ~/ti-sdk-am335x-evm-07.00.00.00/bin/create-sdcard.sh for creating the partitions, 
After creating the partitions I tried implementing step 7. Put U-Boot and the kernel onto the board & step 8. Try it,  by the following steps,
And when I tried to boot I am facing the below error for which am not able to get the uboot prompt

U-Boot SPL 2013.10-g78d8ebd (Mar 30 2014 - 20:46:34)                                       
reading args                                                                               
spl: error reading image args, err - -1                                      
reading u-boot.img                                                           
reading u-boot.img                      
No valid FDT found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d <file.dtb>
initcall sequence 808511ec failed at call 80833f84
### ERROR ### Please RESET the board ###

Steps followed by me
1.
As tmp directory was unavailable while mounting /dev/sdc1, so I created tmp directory while mounting /dev/sdc1 & executed the commands as below
sudo mount /dev/sdc1 /mnt/tmp
sudo cp ~/ti-sdk-am335x-evm-07.00.00.00/board-support/u-boot-2014.07/b/am335x_boneblack_vboot/u-boot.img /mnt/tmp/u-boot.img 
sleep 1
sudo umount /dev/sdc1

sudo mount /dev/sdc2 /mnt/tmp
sudo cp ~/ti-sdk-am335x-evm-07.00.00.00/board-support/linux-3.12.10-ti2013.12.01/work/image.fit /mnt/tmp/boot/image.fit
sleep 1
sudo umount /dev/sdc2

2.

I have even tried copying MLO & u-boot.img of as below, but still the same error where unable to get uboot prompt

sudo cp ~/ti-sdk-am335x-evm-07.00.00.00/board-support/u-boot-2014.07/b/am335x_boneblack_vboot/MLO /media/boot/
sudo cp ~/ti-sdk-am335x-evm-07.00.00.00/board-support/u-boot-2014.07/b/am335x_boneblack_vboot/u-boot.img /media/boot/

am335x-boneblack.dtb  am335x-boneblack-pubkey.dtb  Image  image.fit  Image.lzo  keys  sign.its  u-boot-dtb.img
appusony at appusony-laptop:~/ti-sdk-am335x-evm-07.00.00.00/board-support/linux-3.12.10-ti2013.12.01/work$ sudo image.fit /media/rootfs/boot/

Please do the needful in resolving the above issue as this is the last steps 

Many Thanks in Advance again,

Did you mkdir keys?
