I have a question about spi.

When setting GPIO of cns of spi, Are only certain GPIOs available as CNS?

Or can I configure the CNS with any GPIO?

Hi Kim,

You can use any pin as CSn. This is configured in the board file in the SPI part there. If you wish you can also control a pin directly with the PIN or GPIO drivers. In that case you must leave the SPI-config's CSN pin as unassigned.

You can also find some driver usage examples in the documentation: dev.ti.com/.../

Best regards,
Aslak
