C6678 code image protection

murad qahwash

Hello all,

We are using the C6678 EVM in one of our products and we store our code in NOR. C6678 boots from NOR using the IBL. My question is how to secure our code in NOR or other boot options?. I read about the Secured ROM but very little details out there!

Regards,

Hi Murad,

The documentation and secure boot overview is not publicly available so please get in touch with your local TI contact in order to obtain this information.

Thanks.

Hi Murad,

Secure boot and secure storage is not supported on the C6678 or any other devices in the Keystone I device family.

We currently support secure boot only on K2H and K2E devices which are part of the Keystone II family.

Rahul

Thank you Rahul for the update,

This is really bad news since when we looked at the C6678 datasheet it made it sounds like "secured ROM" is supported. we are using the C6678 EVM with our own adaptor and we are about start building our own DSP board based on the C6678!...looking at the K2H, it doesn't seem an easy migration (pin count, price, requirements, etc)

You may want to explore a solution with an external chip managing the secure boot in your system wherein it authenticates the boot image and establishes a root of trust before getting the C6678 out of reset.
