Beaglebone Secure Boot

[Rohit Pai]

Hello Anil and Team, 

I am trying to implement secure boot sequence on Beaglebone black. 

I need information on how the ROM code inside AM335x verifies the MLO it finds in the bootable device. 

The TRM and some blogs from TI claim that the ROM code is capable of booting a HS (High Security) device but there is no information about how to  configure / achieve this. 

If you know how its done please share it with me. 

Any other pointers also will help. 

thanks

Is secure boot really supported on BBB? Please share those links.

Thanks & Regards
Anil

AM335x does not support secure boot.

Hi Abhilash,

May I know what exactly you mean by secure boot. Is it from hardware side or from software like password mechanism in uboot ?
