there’s CA, “hwkey-app” that is intended to work with the TA, “hwkey-agent”.
so, you’ll need to build the CA sample on the target device, i.e. Jetson AGX Xavier.
please moving on and submit another thread,
let’s see how to help you out and what’s we’ll need to improve with the current JetPack release. (i.e. JetPack-4.5.1)
thanks
