Hi, I have a custom MX8M-PLUS-based board and we are going to use this SOM with a custom Yocto-based Linux distribution. We need to use also the M7 MCU in order to manage few peripherals. The question is, where can I find a documentation explaining which pins can be used by the M7 MCU? How can I communicate with Yocto (maybe using a UART?). It seems that such documentation is not out yet, can you confirm that?
One may check the SDK available, for the peripheral available for the M7,regarding pads you may look into the Reference Manual Chapter 31 External Signals and Pin Multiplexing.
