Rio Chan

In this doc:

file:///C:/Rio_Shared_Folder_2014/AM64_HS_FS_Stuffs/AM64x-Processor-SDK-08_04_01_04-Documentation/08_04_01_04/linux/Foundational_Components_OPTEE.html#foundational-components-optee

Q1.

There are 2 sections:

Building OP-TEE

Building u-boot with OP-TEE OS

Do we must perform those 2 actions? Building OP-TEE + Building u-boot with OP-TEE OS ?

Q2.

I need to perform those steps for HS-FS evm?

make CROSS_COMPILE64=aarch64-none-linux-gnu- PLATFORM=k3-am64x CFG_ARM64_core=y CFG_TEE_CORE_LOG_LEVEL=2 CFG_TEE_CORE_DEBUG=y
$ {TI_SECURE_DEV_PKG}/scripts/secure-binary-image.sh ./out/arm-plat-k3/core/tee-pager_v2.bin ./out/arm-plat-k3/core/tee-pager_v2.bin.signed


Q3.
Following Q2, 
where is the output built files?
What are the files' name?

Hello Rio,
A1: Yes, both steps are neccesary once OP-TEE is rebuilt.
A2: Yes, to sign for HS after OP-TEE is rebuilt
A3: It is noted online "Binary saved saved in: <path-to-optee>/out/arm-plat-k3/core"
Best,
-Hong

I'm curious to know any build error was observed in your OPTEE build?
