AM623: OSPI Secure boot with HS-SE Part

Part Number: AM623
Other Parts Discussed in Thread: AM2432

Tool/software:

Hello,

We're looking to use an HS part with OSPI flash as the boot mode. It seems like currently only SD/MMC is supported for HS-SE because of the Kernel Image needing to be in a FIT Image format, and OSPI has dtb and kernel image in separate partitions. I found this related post talking about the AM2432. Is this feature supported, or if not, will/when would it be available?

Thank you,

David

    While this isn't currently part of the SDK out-of-the-box experience, how about changing the OSPI layout such that you can place and boot such a FIT image? There shouldn't be anything preventing you going down this path to get authenticated boot to work.

    Hi Andreas,

    Thank you for responding. Ok, that's good to know that there isn't a limitation with an OSPI part vs MMC/SD. We will work on repartitioning the flash to get the FIT image to work.
