SP1ML-915 custom firmware

I'm wanting to load a custom firmware onto the SP1ML-915, as I'd like to implement abilities I can't get through the existing AT command set. 

Where can I find documentation about how the STM32L151RB is connected to the Spirit1 chip?  i.e. which spi on what pins? 

Also, does STM32CubeMX offer any help in setting up a base for a this type of firmware?  Would appreciate any pointers, as I'm fairly new to all of this.

I'm also interested about the possible answers to this question. 

That would be a huge benefit to use the stm32 inside the module for our own application (gather some simple acquisitions from a sensor) rather that including another mcu only for that purpose. 

Thank you.

Simply use the P2P example included in STM32CubeExpansion_SUBG1_V1.0.0.

Then you should know that:

PA5     ------> SPI1_SCK

PA6     ------> SPI1_MISO

PA4     ------> SPI1_NSS

PA7     ------> SPI1_MOSI 

PA1     ------> SPIRIT_SDN

PC4      ------> SPIRIT_IRQ0
