Hello World - **DEPRECATED**

2018-01-01: This standalone Hello World TA has been deprecated

We have just recently created another git called optee_examples. The code from this Hello World application has been moved into that optee_examples git, so Hello World resides there as one standalone example together with a few other standalone example host/ta pairs. We will keep this git here as a reference in case someone needs it for historical reasons (links pointing here etc).

Description

This is a reference template to start writing a Trusted Application

Presentation

This example has been presented at the Linaro Connect USA 2014. The slides are available here.
