The MIPI SneakPeek Protocol (MIPI SPPSM) is used to communicate between a debug test system (DTS) and a mobile terminal target system (TS). This communication facilitates using debug applications (typically software) within the DTS to debug the operation of the TS.
The SneakPeek Protocol abstracts the system designer from dedicated debug communication interfaces such as JTAG and replaces them with the familiar mechanism of address-mapped read and write transactions to enable the debug applications to observe, interrogate and adjust the target system.
These transactions might be addressed to main system memory, special function memories, or address-mapped peripherals within the TS. If the system requires legacy dedicated debug communication interfaces to be used internally within part of a system, then these could be constructed by a dedicated address-mapped peripheral within the target system that is then accessed by the DTS via SneakPeek.
MIPI SneakPeek is developed by the MIPI Debug Working Group. It is available in v1.0 and v2.0. All MIPI debug and trace specifications, including MIPI SPP, 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.
