This Application Note is associated with [https://www.dave.eu/en/news-and-media/news/multicore-debug-and-trace-su-nxp-imx8 this webinar] organized by [https://www.lauterbach.com www.lauterbach.it Lauterbach Italy], [https://www.dave.eu DAVE Embedded Systems], and [https://www.nxp.com NXP ] in May 2021.

The webinar showed advanced techniques used to debug , trace, and trace energy profile the code executed by the NXP i.MX8M SoC powering the [[MITO_8M_SOM|Mito8M system-on-module (SoM)]] with the aid of Lauterbach tools. Basically, the hardware platforms used for this demonstration consists of the [[MITO_8M_SOM/MITO_8M_Evaluation_Kit|MITO 8M Evaluation Kit]]. This kit comprises three different boards:

In this regard, it is worth remembering that Mito8M SoM '''is electrically and mechanically compatible with i.MX6-based [[AXEL_Lite_SOM|AxelLite SoM]]'''. Therefore, '''Mito8M can be mated with the SBCX carrier board directly'''. Nevertheless, to fully leverage all the functionalities it providsprovides, an adapter board is required. Namely, the adapter board allows to access physical interfaces that are used for the purposes here discussed.

For what regards the software configuration, a typical Linux SMP setup was used. Specifically, the kernel TBD was used utilized in tandem with a root file system built with Yocto TBD.

In essenceWith respect to tracing, three topics will be different strategies are illustrated:* Onchip trace* Offchip trace via Trace Port Interface Unit (TPIU)* Offchip trace via PCIe.
