Hi Diwakar,

1.Currently we are using general purpose device which is available online, it is mentioned that general purpose device won't support secure boot if I'm right. If so please let us know which device is available to order to check secure boot.

2.We are using custom board and not any SDK for testing

Secure boot is supported on HS devices. On GP there is no provision to fuse the root trust keys that is the reason secure boot is not supported on that.

On HS-FS device keys are blown to the effuses using keywriter tool , once that is done the device get converted to HS-SE (High Secure Security Enforced device ).To understand more on this please refer app note.

Let me loop other expert for ordering process.

By means of SDK is it Linux sdk or RTOS sdk.
