It depends a bit on the type of SoC you are using.
So possibly you need to use GPIO lines to for the chipselect between
the two devices.
For each SPI device you can specify which GPIO line to use to select
the connected SPI device.
But as said all but the last question depend on the type of SoC.
Dears:
Due to limit hardware platform SPI port, we are considering to share one SPI
port for two devices, such as WiFi and GPS.
Has someone done like that?
Do you have estimated workload?
Is there any risky?
Many thanks for sharing your information on SPI.
