How to port OP-TEE for SABRESD-6DQ android?

[Sun1z]

Currently I want to port a fingerprint to sabresd-6dq board, with android 7.1.1 installed, as which requires a TEE OS, I wonder anyone have ported optee for it? or NXP have other available TEE OS for it? so far I have tried optee source from github but failed that the compiler for AOSP doesn't support compiling optee-client.

Best regards,

Sun

Hi, I am working on Linux, boot.img is booted by code in ROM, and I use bootm to boot tee.bin.

Hi,Yiling Xu 

   Thanks for your apply,I do not understand the meaning of "boot.img is booted by code in ROM",  the ROM means u-boot or another bootloader? because I used u-boot to boot boot.img. so can you describe more details about how to boot both boot.img and tee.bin?Thanks a lot!

Hi, ROM containing startup scripts (that is, boot code), the code in ROM is executed first after power on, and  we can not change the code in ROM. We can only configure "SW6-Boot Mode" to boot the smart device from different storage, eg. SD card or MMC.
