Cortex M7 pinout on Verdin i.MX8M plus board

I would like to use SPI and GPIO directly on the cortex M7 using RTOS.
Could you please help me with the pin-out diagram of the Verdin i.MX8M Plus board that shows the pins of the cortex M7?

First of all iMX8mm SOC has no cortex M7 only M4. Second - Cortex M4 has no dedicated SPI or GPIO pins. The signal-to-pin and pin-to-signal options are selected by the input-output multiplexer
called IOMUX. Then some peripheral blocks like Enhanced Configurable SPI are separate from Core entity and can be accessed by any ( M4 or A53) core . Please check the i.MX 8M Plus Applications Processor Reference Manual for details

I’m referring to the i.MX8M plus, not the i.MX8mm.

In the reference manual you provided, I discovered that the i.MX8M Plus has M7.

Yes, you are right iMX8M plus has a M7 core. However it has no dedicated SPI or GPIO pins. The signal-to-pin and pin-to-signal options are selected by the input-output multiplexer called IOMUX.
