On Lairds SOM 8M Plus System on Module, how is the radio connected to the host processor?

Answer

The interface the 60-series radio on the SOM 8M Plus system on module connects to the iMX8MP host processor is selectable in software to allow for choosing between lower power consumption and higher performance.

There are 5 options:

Description                             Radio Mode Parameter Value (set-radio-mode )  PCIe and UART(default                   pcie-uart  SDIO and UART                           sdio-uart  SDIO and UART (Stop upon shutdown)      sdio-uart-stop  SDIO and UART (Suspend upon shutdown)   sdio-uart-susp  SDIO and SDIO                           sdio-sdio

The command to set the interface option is:
