Building AOSP + OPTEE for Hikey 960



I build AOSP+OPTEE using , and run android successfully, but I couldn’t find way to run xtest.

The kernel driver are already there–/dev/tee0,/dev/teepriv0;
dmesg | grep tee
[ 6.442064] optee: probing for conduit method from DT.
[ 6.450743] optee: initialized driver

And when I ran tee-supplicant&, the information is listed below.
[1] 4416
/system/bin/sh: tee-supplicant: not found
