MIPI SyS-T is a common data format for transmitting software trace and debug information between a test system and a device, such as a system-on-chip (SoC) or platform. MIPI Alliance offers the specification to developers as part of the Open Source Initiative. An accompanying implementation library is available to the GitHub community.

MIPI SyS-T addresses a very real need in the debug and test industry for a universal data format that can be used to exchange debug information across software, firmware or hardware implementations. It provides a convenient, vendor- and OS-agnostic approach to alleviate fragmentation caused by solutions associated with specific vendors or operating systems. It complements the MIPI Alliance debug and test portfolio because it can be used with any MIPI Alliance debugging tool or transport protocol.

Developers will find that MIPI SyS-T makes it easier to integrate their embedded software with underlying hardware. It enables hardware vendors to use software solutions from more organizations. Debug and test tooling vendors can use the specification to offer generic testing products for developers and manufacturers.

The specification includes the trace formatting method as well as an optional MIPI SyS-T Instrumentation Library, which includes APIs and documentation that developers can use to jumpstart their use of the specification rather than starting from scratch.

MIPI Alliance encourages GitHub developers to use, modify and share the specification and library, provide feedback and interact with others in the user community.
