    Hello Jiankang,

    The OPTEE OS is built and is incorporated into the A72 U-Boot build flow alongside ATF (Arm Trusted Firmware).

    Please see the generic build instructions in the TI U-Boot source code. The actual tree and versions used in SDK is a downstream ti-optee-os tree, and the version used is exactly equivalent to upstream OPTEE 3.12 version.

    The TI K3 platforms reserve and use 24 MB of DDR memory at 0x9e800000. The same is reserved in the board dts file under the reserved-memory node.

    The OPTEE memory reservation is provided through couple of config variables in the TI K3 platform specific configuration file in OPTEE OS source code. If you want to customize, you can build OPTEE OS by passing these to the make command. Please make sure your board dts file reserves the corresponding memory.

    regards
