I am trying to bring up OP TEE in LS1012A FRWY, and have read through LSDK document and manual in
OP-TEE , however, these documents don't solve all the questions. Anyone have detailed steps how to bring up OP TEE ?
1) Do I have to enable secure boot to run OP TEE?
2) From, I learned that I need to generate a ppa.itb file by using
$ flex-builder -c ppa-optee -m ls1012afrwy
which generate flexbuild/build/firmware/ppa/soc-ls1012/ppa.itb.
Then what? the document doesn't complete the puzzle. How do I use that file? Do I need to manually burn it in the Nor flash? and How?
3) I also learned I need to create a OPTEE-OS binary by using
$ flex-builder -c optee_os -m ls1012afrwy
which outputs the bin file to flexbuild/packages/apps/optee_os/out/arm-plat-ls/core/tee_ls1012afrwy.bin
Again, it is confusing how can I use that file, what is next step ?
4) In How to build Trusted Applications for the OP-TEE , I know I have to build client , test and OS to run the tests:
