Hi,

I previously used imx8mm which has support for CAAM. However,  when switching to imx93 this is no longer supported. What alternatives are there on the imx93 when wanting to store data on emmc, and reading it out in an secure manner?

In u-Boot.

Hi,

The alternative is ELE for i.MX93. What size the data will be. Please share scenarios and more details.

Hi Harvey,

It's only a few bytes, less than 32B. Ideally I would like to read it out early in the boot process, in the SPL. And I would also like to be able to change the data from both u-boot and the Linux kernel.

Please let me know if there is anything else that is unclear.
