I have been following instructions on link to setup AOSP on the Hikey 620 board.
When I finish compiling the code, I notice that the installer folder contains a fip.bin file. My understanding is that fip.bin contains the TEE OS code. When AOSP + OPTEE manifest is used, the OPTEE compilation will be put in fip.bin. Now in the case of a clean AOSP compilation (when no OPTEE code is added), what is present in the fip.bin file ?
Thanks.
