MIPI Alliance has a family of specifications that can be used to debug components in mobile devices as well as any device that is “smart” or connected, such as an end-point on the Internet of Things. Components that can be debugged with the tools include application processors, modems, device controllers, power management devices, and others.
All of these specifications are available for download and use by the public and the open source community.
MIPI Debug for I3CSM is a bare-metal, minimal-pin interface for transporting debug controls and data between a debug and test system (DTS) and a target system (TS). The specification uniquely handles the network topology in a dynamic fashion, making it perfectly suited as a flexible and scalable debug and test specification for systems that enable mobile, the Internet of Things (IoT), automotive and other use cases.
MIPI Debug for I3C allows system designers to efficiently and dynamically debug and test application processors, power management integrated circuits, modems and other power-managed components across a system of any size via the low-bandwidth MIPI I3C® interface, which requires a minimal set of pins.
MIPI Debug for I3C was developed by the MIPI Debug Working Group. All MIPI debug and trace specifications, including MIPI Debug for I3C, are available for download and use by the public and the open-source community. Members of the MIPI Alliance enjoy benefits including access to relevant licenses and opportunities to participate in development activities, interoperability workshops and other events.

Legacy debug solutions that are statically structured—such as JTAG/cJTAG, I2C and UART—lead to limited scalability for the accessibility of debug components/devices—for example, when they’re in low-power mode. MIPI Debug for I3C overcomes these restrictions by building on key MIPI I3C v1.1 features. MIPI Debug for I3C delivers multi-component connectivity across either dedicated debug or shared bus topologies, requires only two wires, supports multiple entry points, and maintains a network even as components power down and off a network and then rejoin after powering back up.
