I follow the directions on github and then loaded the kernel drivers. Next, I tried to run
tee-supplicant &and got the error message below.
armv7sec armv7sec.0: shm service not available: FFFFFFFF misc opteearmtz00: tee_get: opteearmtz00::start() failed, err=-22
Then tee-supplicant exits. If try to run tee-supplicant again I get the following error.
misc opteearmtz00: tee_get: opteearmtz00::start() failed, err=-22 armv7sec armv7sec.0: tee_supp_open: ERROR Only one Supplicant is allowed
Which would imply the tee-supplicant is still running. But all of my xtest fail. Did I miss something in the directions?
