Hi again,
Thank you for your reply. I actually took a look at the wiki before, and I managed to build the pure AGL (7.99.3) for rpi3 B+. In fact, I'm still stuck at the similar step. As I mentioned before, I followed https://github.com/benhaz1024/raspbian-tee to build OPTEE for AGL. While the build was successful, many of the modules fail to be loaded during the boot time, and I can't even log in. I'm guessing this is because now there are two module directories at /root/lib/modules/ (There are currently 4.14.98 dir from pure AGL build and 4.14.98-v7 from OPTEE build), and all the modified u-boot and uImage files are looking at 4.14.98-v7 directory. If this is the case, what would be a possible approach? Should I find a way to build OPTEE stuff along with AGL instead of building separately and combining? FYI I've attached the current boot log.
I'd really appreciate if you can help me a bit.. I've been working on putting OPTEE on AGL for RPI3 B+ over the last two weeks. Please let me know if there's any unclear explanation.NOTICE: Booting Trusted Firmware
