Die root key in imx93

[RDSIMARIA]

Hello Team,

We need to use unique key for each device in our application. We came to know about Die root key from imx93 SRM.

How can we use Die root key on OS level?

Hi 

To use Die root key, at present, you can refer to imx-optee-os/core/drivers/crypto/ele/ele.c at lf-6.1.36-2.1.0 · nxp-imx/imx-optee-os · GitHub

Hello team ,

1. We are using kernel version "lf-6.1.1_1.0.0". in my "imx-optee-os" i don't have ele (Edgelock Enclave) in it and we don't want to upgrade kernel. How we can use ele (Edgelock Enclave) in same kernel version (lf-6.1.1_1.0.0) or how can we incorporate ele (Edgelock Enclave) in our.

2. How to check driver is successfully added in file system

3. How to read or test the die root key using command line, after ele (Edgelock Enclave) support added. Or can we have any end to end document available for ele (Edgelock Enclave).
