I have purchased a Hikey board to test out OPTEE with Android. My board is set to arrive today and I have gone through tutorials for setting up OPTEE and Android independently but not together. Has any one tried this combination before and can someone share the steps for the same. Also will I require a uart cable to view the secure world console debugger? All my past development was done on QEMU, this is the first time I have purchased a physical board.
