the latest LSDK:08_02_00_23

compile cmd:

Getting the OP-TEE Source Code
$ git clone https://github.com/OP-TEE/optee_os.git

Getting Security Dev Tool

$ git clone git://git.ti.com/security-development-tools/core-secdev-k3.git -b master
$ export TI_SECURE_DEV_PKG=`pwd`/core-secdev-k3

Building OP-TEE
on GP
$ make CROSS_COMPILE64=aarch64-linux-gnu- PLATFORM=k3-am65x CFG_ARM64_core=y

out:./out/arm-plat-k3/core/tee-pager_v2.bin

then:
A53
$ make ARCH=arm CROSS_COMPILE=aarch64-none-linux-gnu- am64x_evm_a53_defconfig O=<output directory>/a53
$ make ARCH=arm CROSS_COMPILE=aarch64-none-linux-gnu- ATF=./bl31.bin TEE=./tee-pager_v2.bin  O=<output directory>/a53

copy tispl.bin, u-boot.img from output/a53 to sd part

then power on the board:

    Hello,
    Please let us know which board and SoC (GP or HS) you're testing with?
    There's an early e2e post on OPTEE to see if it helps.
