BKK19-419 - Debugging with OP-TEE

Session Abstract

Debugging trusted applications (and OP-TEE itself) can be difficult because, for very good reasons, secure software is often reluctant to disclose information about its operation to the non-secure world, meaning is does not have access to the rich facilities in operating systems such as GNU/Linux that would normally be used for system level debug.

In this session we will discuss the common debug techniques used to debug secure applications. We will also look at how it is possible to implement function tracing to help solve problems, especially on platforms where JTAG debug is unavailable.
