hello mwesigwa.guma,
got it, thanks for confirmation.
as you can see..
here’s Random fixed vector, which MUST match the ‘fv’ vector used for EKB binary.
$public_sources/r35.6.x/Linux_for_Tegra/source/public/atf_and_optee/optee/optee_os/core/pta/tegra/jetson_user_key_pta.c
// Random fixed vector for EKB
static uint8_t fv_for_ekb[] = {
0xba, 0xd6, 0x6e, 0xb4, 0x48, 0x49, 0x83, 0x68,
0x4b, 0x99, 0x2f, 0xe5, 0x4a, 0x64, 0x8b, 0xb8,
besides update op-tee binaries, you should also update tos.img for using customize FVs.
you may see-also Topic 263994 for reference.
