PROCESSOR-SDK-DRA8X-TDA4X: Secure boot on PROCESSOR-SDK-LINUX-DRA8X-TDA4X release 7

Hi Amit,

Can you elaborate a bit more on what you want to accomplish? When you say secure boot
do you have a HS(High secure) device for TDA4?

Hi Keerthy,

We want to enable the integrity check on linux as we are using the PSDLA release. DM-verity is enabled in Android for same.

We can create the hash with dm-verity. But in current TI bootflow we want to know how this verification can be done. 

If you have some different solution for the same do let us know.

Best regards

Amit

Hi Amit,

In case of Android, the Android framework by default has the support for generating file system images (system.img, etc..) suitable for using with dm-verity. The support for dm-verity in kernel is also standard component.
Only support needed from TI SDK was crypto support in Linux kernel for SHA operations.

I am not sure which components are needed on the Linux filesystem to generate images that can be used with dm-verity enabled Kernel.
We have not looked in to this.

But secure device boot flow till you reach to Kernel is a separate topic.

Hi Karan,

Can you point me to documentation for secure boot till kernel load. I will close the issue after that.

Best regards

Amit

Hi Amit,

Are you having HS samples? We do not have any documentation of SDK 7.0 for that right now.
