Re: [U-Boot] verified boot of beaglebone black

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/

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

When I was generating the keys ie., Step 4: Create a key pair

Am facing one more error while generating private key & certificate containing public key used for verification when I execute the below openssl commands it is saying can't open config file:

Did you mkdir keys?
