[U-Boot] u-boot hangs after enabling secured boot : gumstix-overo

[Arun Kuttiyara Varghese]

Hi All,

I was trying to enable the secured boot in u-boot for gumstix overo storm.

based on http://www.denx-cs.de/doku/?q=m28verifiedboot

After I prepared by SD cards, u-boot is not able to boot
and gives the below error message.


U-Boot SPL 2015.07 (Apr 28 2016 - 13:53:06)
SPL: Please implement spl_start_uboot() for your board
SPL: Direct Linux boot not active!
reading u-boot.img
spl_load_image_fat: error reading image u-boot.img, err - -1
SPL: Please implement spl_start_uboot() for your board
SPL: Direct Linux boot not active!
Failed to mount ext2 filesystem...
spl_load_image_ext: ext4fs mount err - 0

================

This is the u-boot.dts file that I am using.


/dts-v1/;

/ {
        model = "Keys";

        signature {
                key-dev {
                        required = "conf";
                        algo = "sha1,rsa2048";
                        key-name-hint = "my_key";
                };
        };
};

compilation using :
dtc -p 0x1000 /work/u-boot.dts -O dtb -o /work/u-boot.dtb

And these are the conf that I have added to include/configs/omap3_overo.h

 #define CONFIG_OF_CONTROL
 #define CONFIG_OF_SEPARATE
 #define CONFIG_FIT
 #define CONFIG_FIT_SIGNATURE
 #define CONFIG_RSA
 #define CONFIG_FIT_VERBOSE

and I am compiling u-boot by using below line :

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- EXT_DTB=/work/u-boot.dtb all
-j4

Please let me know if you have any ideas on how to debug this issue.

Thanks & Regards,
Arun
