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
