Pinout of OSM-S i.MX8M Mini
The pinout described here is the default pinout of the SoM in comparison to the OSM pinout. One can use
Pins Tool for i.MX Application Processors
multiplexing.
The tool can be downloaded from nxp homepage.
Changing the multiplexing creates the need of changing the device tree too.
