Hi Simon, Thanks for the help.
There is an update. I experimented with the two options. Option 1 ===== Like you mentioned, I tried putting all the RSA boot options to configs/omap3_overo_defconfig. but surprisingly, the board was not able to boot. it stucks after printing one line of junk characters. So I think, putting definitions in include/configs/omap3_overo.h is also fine ? Option 2 ==== 1. changed u-boot-dtb.img name to u-boot.img . 2. then board is able to boot, but gives the below message when I tried to use bootm. Overo # ## Loading kernel from FIT Image at 82000000 ... Using 'conf@1' configuration Verifying Hash Integrity ... sha1,rsa2048:my_keyRSA: Can't find Modular Exp implementation RSA: Can't find Modular Exp implementation - Failed to verify required signature 'key-my_key' Bad Data Hash ERROR: can't get kernel image! Overo # As mentioned in doc/uImage.FIT/beaglebone_vboot.txt, I tried the script - tools/fit_check_sign, and its output is normal. Able to verify the signature. So still dont know, what is the exact issue, why I am getting the above error message. I searched for UCLASS_MOD_EXP, /* RSA Mod Exp device */, but couldn't get much info. What is RSA Mod Exp device and how to make sure that I have that ? Any input to debugging will be greatly helpful.
