How many SPI channels available to network core on nrf5340?

[JonasForssell]

Dear nrf5340 experts,

How many SPI channels are accessable from the network core in nrf5340?

I need 2 or more. 

If this is not available, is there a workaround?

Many thanks

There is only a single SPI master peripheral associated with the network core (See SPIM chapter in the product specification).

Regarding workaround, I would first consider using the application core instead. However, while it is not supported, the network core can have access to application core memory and peripherals, so it may be possible to do something. I do not have any specific guidance regarding that though, but you can refer to this old thread.
