MIPI offers debug specifications for mobile and IoT: Page 3 of 3

January 20, 2016 //By Jean-Pierre Joosting
Gary Cooper, former chair of the MIPI Alliance Debug Working Group and systems engineer at Texas Instruments, discusses forthcoming specifications that should make debugging mobile phone designs easier, and could be picked up in other mobile equipment and IoT

Expanding the paradigm with NIDnT and High Speed Trace

The MIPI Alliance is also expanding the traditional debug and testing paradigm by developing capability to perform hardware debug and trace on production or near-production terminals using physical ports available on a device. A forthcoming update to the MIPI Narrow Interface for Debug and Trace (NIDnT) will leverage the use of the USB Type-C interface for this function. A first draft should be released by the end of this year.

A standalone MIPI High Speed Trace Interface (HTI), also in development, will support exporting trace data over high-speed serial links, such as digital display interfaces, to an external trace receiver. This interface will be approved by the board in the first quarter of 2016. Figure 2 illustrates how NIDnT 1.1 and HTI are deployed.
