How do I access a second SPI chip select, when using a SPI bus?

Using Torizoncore 6, Verdin Dev board.
I am using the SPI bus with one device, but I need to access another device and therefore need another Chip select. Is this even possible?

Thanks,
Steve

Hey @Evets,

You should be able to add chip select to the existing SPI with a designated GPIO pin of your configuration/choosing… This modification would need to be present in the device tree and can be done via overlays.

Here is information on how to preform overlays.

Here is the driver information for SPI. Which would lead us to the spi-controller docs that describe cs-gpios as chip selects.
