Hi experts,
I'm wondering do you compile the OPTEE_OS in this instruction as arm32 or AArch64? In which script do you set the compiler for the secure OS? ( I checked the file build-optee-os.sh while I find the file exports both compilers so I'm not sure which one is used for compiling OPTEE_OS actually.)
Also, if it's still using 32-bit architecture, is it possible for me to compile the secure OS as 64-bit OS to access entire DRAM address?
Thank you.
