Thanks for your instructions, Phil.PhilE wrote:You are in luck. The current RPi SPI driver, spi-bcm2835, support GPIO chip-selects. This means that any free GPIO line can be used as another chip select. In fact, as a result of some driver performance optimisations causing the hardware ("native") chip-selects to glitch, the driver will automatically convert native CS's to GPIO CS's.

If you change the config to is2_arm=on I'm assuming it uses 18-21. How does one enable I2S on pins 28-31 rather than the default 18-21?PhilE wrote:I'm sorry, but that isn't possible. If you download the BCM2835 ARM Peripherals documentation from here and turn to pages 102-103 you will see a map of the alternate functions available on each GPIO pin. The I2S functions are labelled as PCM, and appear in two groups - 18-21 and 28-31. Later Models A and B use 28-31 brought out onto a separate header (P5), but the Pluses and Pi 2 use 18-21 for I2S, the other group being used for I2C and as GPIOs to control on-board devices.
So the declarations of pin usage in Device Tree has prevented you from making a configuration error. By not enabling I2S you would be able to use GPIO18, and vice-versa, but you can't have both. (I realise you may know this, but not all readers will.)
