[lx2160a] Does lx2160a support emmc secure boot ?

[Jeffrey_Lai]

Hi NXP,

We want to enable secure boot on LX2160ARDB by LSDK.

During building secure system image, we see the following message

nandboot secure on lx2160ardb: unsupported
emmcboot secure on lx2160ardb: unsupported

and get xspiboot_secure.img and sdboot_secure.img finally.

Does LX2160A support emmc secure boot?

If yes, how to enable it ?

Please give us advice. thank you.

LX2160A supports emmc secure boot.

Please define the following in configs/board/lx2160ardb_rev2/manifest

atf_bl2_emmc_sec=$FBOUTDIR/firmware/atf/lx2160ardb_rev2/bl2_emmc_sec.pbl

Then run the following command to get build/firmware/atf/lx2160ardb_rev2/bl2_emmc_sec.pbl.

$ flex-builder -c atf -m lx2160ardb_rev2 -b emmc -s

Please program image sdboot_secure.img to eMMC card, then program bl2_emmc_sec.pbl at block 8 of your eMMC card.
